    Cell death-inducing p53-target protein 1 (CDIP1) is a proapoptotic protein that is normally expressed at low levels and is upregulated by genotoxic and endoplasmic reticulum stresses. CDIP1 has been reported to be localized to endosomes and to interact with several proteins, including B-cell receptor-associated protein 31 (BAP31) and apoptosis-linked gene 2 (ALG-2). However, the cellular and molecular mechanisms underlying CDIP1 expression-induced apoptosis remain unclear. In this study, we first demonstrated that CDIP1 was upregulated after treatment with the anticancer drug adriamycin in human breast cancer MCF-7 cells but was degraded rapidly in the lysosomal pathway. We also demonstrated that treatment with the cyclin-dependent kinase 5 (CDK5) inhibitor roscovitine led to an increase in the electrophoretic mobility of CDIP1. In addition, a phosphomimetic mutation at Ser-32 in CDIP1 resulted in an increase in CDIP1 expression-induced apoptosis. We also found that CDIP1 expression led to the induction of autophagy prior to apoptosis. Treatment of cells expressing CDIP1 with SAR405, an inhibitor of the class III phosphatidylinositol 3-kinase VPS34, caused a reduction in autophagy and promoted apoptosis. Therefore, autophagy is thought to be a defense mechanism against CDIP1 expression-induced apoptosis.

    Environmental factors are important regulators of cell growth and proliferation. Mechanistic target of rapamycin (mTOR) is a central kinase that maintains cellular homeostasis in response to a variety of extracellular and intracellular inputs. Dysregulation of mTOR signaling is associated with many diseases, including diabetes and cancer. Calcium ion (Ca2+) is important as a second messenger in various biological processes, and its intracellular concentration is tightly regulated. Although the involvement of Ca2+ mobilization in mTOR signaling has been reported, the detailed molecular mechanisms by which mTOR signaling is regulated are not fully understood. The link between Ca2+ homeostasis and mTOR activation in pathological hypertrophy has heightened the importance in understanding Ca2+-regulated mTOR signaling as a key mechanism of mTOR regulation. In this review, we introduce recent findings on the molecular mechanisms of regulation of mTOR signaling by Ca2+-binding proteins, particularly calmodulin (CaM).

    We previously reported that hepatitis C virus (HCV) infection activates the reactive oxygen species (ROS)/c-Jun N-terminal kinase (JNK) signaling pathway. However, the roles of ROS/JNK activation in the HCV life cycle still remain unclear. We sought to identify a novel role of ROS/JNK signaling pathway in the HCV life cycle. Immunoblot analysis revealed that HCV-induced ROS/JNK activation promoted phosphorylation of Itch, a HECT-type E3 ubiquitin ligase, leading to activation of Itch. The siRNA-knockdown of Itch significantly reduced the extracellular HCV infectivity titers, HCV RNA, and HCV core protein without affecting intracellular HCV infectivity titers, HCV RNA, and HCV proteins, suggesting that Itch is involved in release of HCV particles. HCV-mediated JNK/Itch activation specifically promoted polyubiquitylation of an AAA-type ATPase VPS4A, but not VPS4B, required to form multivesicular bodies. Site-directed mutagenesis revealed that two lysine residues (K23 and K121) on VPS4A were important for VPS4A polyubiquitylation. The siRNA-knockdown of VPS4A, but not VPS4B, significantly reduced extracellular HCV infectivity titers. Co-immunoprecipitation analysis revealed that HCV infection specifically enhanced the interaction between CHMP1B, a subunit of endosomal sorting complexes required for transport (ESCRT)-III complex, and VPS4A, but not VPS4B, whereas VPS4A K23R/K121R greatly reduced the interaction with CHMP1B. HCV infection significantly increased ATPase activity of VPS4A, but not VPS4A K23R/K121R or VPS4B, suggesting that HCV-mediated polyubiquitylation of VPS4A contributes to activation of VPS4A. Taken together, we propose that HCV-induced ROS/JNK/Itch signaling pathway promotes VPS4A polyubiquitylation, leading to enhanced VPS4A-CHMP1B interaction and promotion of VPS4A ATPase activity, thereby promoting the release of HCV particles. IMPORTANCE ROS/JNK signaling pathway contributes to liver diseases, including steatosis, metabolic disorders, and hepatocellular carcinoma. We previously reported that HCV activates the ROS/JNK signaling pathway, leading to the enhancement of hepatic gluconeogenesis and apoptosis induction. This study further demonstrates that HCV-induced ROS/JNK signaling pathway activates the E3 ubiquitin ligase Itch to promote release of HCV particles via polyubiquitylation of VPS4A. We provide evidence suggesting that HCV infection promotes the ROS/JNK/Itch signaling pathway and ESCRT/VPS4A machinery to release infectious HCV particles. Our results may lead to a better understanding of the mechanistic details of HCV particle release.

  4. Amino Acid-Mediated Intracellular Ca2+ Rise Modulates mTORC1 by Regulating the TSC2-Rheb Axis through Ca2+/Calmodulin. Reviewed International journal

    Mechanistic target of rapamycin complex 1 (mTORC1) is a master growth regulator by controlling protein synthesis and autophagy in response to environmental cues. Amino acids, especially leucine and arginine, are known to be important activators of mTORC1 and to promote lysosomal translocation of mTORC1, where mTORC1 is thought to make contact with its activator Rheb GTPase. Although amino acids are believed to exclusively regulate lysosomal translocation of mTORC1 by Rag GTPases, how amino acids increase mTORC1 activity besides regulation of mTORC1 subcellular localization remains largely unclear. Here we report that amino acids also converge on regulation of the TSC2-Rheb GTPase axis via Ca2+/calmodulin (CaM). We showed that the amino acid-mediated increase of intracellular Ca2+ is important for mTORC1 activation and thereby contributes to the promotion of nascent protein synthesis. We found that Ca2+/CaM interacted with TSC2 at its GTPase activating protein (GAP) domain and that a CaM inhibitor reduced binding of CaM with TSC2. The inhibitory effect of a CaM inhibitor on mTORC1 activity was prevented by loss of TSC2 or by an active mutant of Rheb GTPase, suggesting that a CaM inhibitor acts through the TSC2-Rheb axis to inhibit mTORC1 activity. Taken together, in response to amino acids, Ca2+/CaM-mediated regulation of the TSC2-Rheb axis contributes to proper mTORC1 activation, in addition to the well-known lysosomal translocation of mTORC1 by Rag GTPases.

    ALG-2 is a penta-EF-hand Ca2+-binding protein and interacts with a variety of proteins in mammalian cells. In order to find new ALG-2-binding partners, we searched a human protein database and retrieved sequences containing the previously identified ALG-2-binding motif type 2 (ABM-2). After selecting 12 high-scored sequences, we expressed partial or full-length GFP-fused proteins in HEK293 cells and performed a semi-quantitative in vitro binding assay. SARAF, a negative regulator of store-operated Ca2+ entry (SOCE), showed the strongest binding activity. Biochemical analysis of Strep-tagged and GFP-fused SARAF proteins revealed ubiquitination that proceeded during pulldown assays under certain buffer conditions. Overexpression of ALG-2 interfered with ubiquitination of wild-type SARAF but not ubiquitination of the F228S mutant that had impaired ALG-2-binding activity. The SARAF cytosolic domain (CytD) contains two PPXY motifs targeted by the WW domains of NEDD4 family E3 ubiquitin ligases. The PPXY motif proximal to the ABM-2 sequence was found to be more important for both in-cell ubiquitination and post-cell lysis ubiquitination. A ubiquitination-defective mutant of SARAF with Lys-to-Arg substitutions in the CytD showed a slower degradation rate by half-life analysis. ALG-2 promoted Ca2+-dependent CytD-to-CytD interactions of SARAF. The ALG-2 dimer may modulate the stability of SARAF by sterically blocking ubiquitination and by bridging SARAF molecules at the CytDs.

    The mechanistic target of rapamycin complex 1 (mTORC1) is an essential regulator of cell growth and metabolism through the modulation of protein and lipid synthesis, lysosome biogenesis, and autophagy. The activity of mTORC1 is dynamically regulated by several environmental cues, including amino acid availability, growth factors, energy levels, and stresses, to coordinate cellular status with environmental conditions. Dysregulation of mTORC1 activity is closely associated with various diseases, including diabetes, cancer, and neurodegenerative disorders. The discovery of Rag GTPases has greatly expanded our understanding of the regulation of mTORC1 activity by amino acids, especially leucine and arginine. In addition to Rag GTPases, other factors that also contribute to the modulation of mTORC1 activity have been identified. In this review, we discuss the mechanisms of regulation of mTORC1 activity by particular amino acids.

    <p>Adenosine 5’-triphosphate (ATP), the major energy currency of the cell, is involved in many cellular processes, including the viral life cycle, and can be used as an indicator of early signs of cytopathic effect (CPE). In this study, we demonstrated that CPE can be analyzed using an FRET-based ATP probe named ATP indicator based on Epsilon subunit for Analytical Measurements (ATeam). The results revealed that as early as 3 hr, the virus infected cells showed a significantly different Venus/cyan fluorescent protein (CFP) ratio compared to the mock-infected cells. The ATeam technology is therefore useful to determine the early signs of ATP-based CPE as early as 3 hr without morphology-based CPE by light microscopy, and enables high throughput determination of the presence of microorganisms in neglected samples stored in laboratories.</p>

    Ubiquitinated membrane proteins such as epidermal growth factor receptor (EGFR) are delivered to early endosomes and then sorted to lysosomes via multivesicular bodies (MVBs) for degradation. The regulatory mechanism underlying formation of intralumenal vesicles en route to generation of MVBs is not fully understood. In this study, we found that SH3YL1, a phosphoinositide-binding protein, had a vesicular localization pattern overlapping with internalized EGF in endosomes in the degradative pathway. Deficiency of SH3YL1 prevents EGF trafficking from early to late endosomes and inhibits degradation of EGFR. Moreover, we show that SH3YL1 mediates EGFR sorting into MVBs in a manner dependent on its C-terminal SH3 domain, which is necessary for the interaction with an ESCRT-I component, Vps37B. Taken together, our observations reveal an indispensable role of SH3YL1 in MVB sorting and EGFR degradation mediated by ESCRT complexes.

    Apoptosis-linked gene 2 (ALG-2) is a Ca2+-binding protein with five repetitive EF-hand motifs, named penta-EF-hand (PEF) domain. It interacts with various target proteins and functions as a Ca2+-dependent adaptor in diverse cellular activities. In the cytoplasm, ALG-2 is predominantly localized to a specialized region of the endoplasmic reticulum (ER), called the ER exit site (ERES), through its interaction with Sec31A. Sec31A is an outer coat protein of coat protein complex II (COPII) and is recruited from the cytosol to the ERES to form COPII-coated transport vesicles. I will overview current knowledge of the physiological significance of ALG-2 in regulating ERES localization of Sec31A and the following adaptor functions of ALG-2, including bridging Sec31A and annexin A11 to stabilize Sec31A at the ERES, polymerizing the Trk-fused gene (TFG) product, and linking MAPK1-interacting and spindle stabilizing (MISS)-like (MISSL) and microtubule-associated protein 1B (MAP1B) to promote anterograde transport from the ER.

    Luciferase reporter gene systems based on the NFAT-response element (RE) have been used to monitor intracellular Ca2+ elevation. However, Ca2+ mobilization agent (e.g., ionomycin) alone is not adequate to activate the currently often employed reporter gene that contains the NFAT-RE found in the IL2 promoter. In addition to activation of NFAT through the Ca2+-calmodulin/calcineurin pathway, activation of AP-1 as a partner transcription factor is essential for the IL2-based NFAT-RE system. Here, we describe a detailed method for the recently developed new reporter gene system containing the NFAT-RE from the IL8 promoter. This system enables us to monitor endpoint effects of Ca2+-mobilizing agonists independent of AP-1 activation.

    MAP1B (microtubule-associated protein 1B) binds to microtubules and regulates microtubule dynamics. Previously, we showed calcium-dependent interaction between MAP1B and a calcium-binding protein ALG-2 (apoptosis-linked gene 2), which is involved in regulation of the protein secretion pathway. Although ALG-2 generally binds to proteins through two consensus binding motifs such as ABM-1 and ABM-2, the absence of these motifs in MAP1B suggests a unique binding mode between MAP1B and ALG-2. Here, we identified the region of mouse MAP1B responsible for binding to ALG-2, and found point mutations that abrogated binding of MAP1B to ALG-2. Furthermore, interaction between MAP1B and ALG-2 selectively prevented ALG-2 from binding to proteins with ABM-2 such as Sec31A, suggesting competition between MAP1B and ABM-2-containing proteins for binding to ALG-2. Consistently, in MAP1B knockout cells, co-localization of ALG-2 with Sec31A was increased. Moreover, overexpression of wild-type MAP1B, but not the MAP1B mutant defective in ALG-2 binding, altered localizations of ALG-2 and Sec31A into dispersed distributions, suggesting that MAP1B regulates localizations of ALG-2 and Sec31A in the cells. Finally, we found two cancer-associated mutations of human MAP1B located near ALG-2 binding sites. The introduction of the corresponding mutations in mouse MAP1B dramatically reduced the binding ability to ALG-2. Thus, these results suggest that MAP1B plays a role in regulation of ALG-2 and Sec31A localizations, and that dysregulation of calcium-dependent binding of ALG-2 to MAP1B might influence pathological conditions such as cancers.

    NFAT is a cytoplasm-localized hyper-phosphorylated transcription factor that is activated through dephosphorylation by calcineurin, a Ca2+/calmodulin-dependent phosphatase. A non-palindromic NFAT-response element (RE) found in the IL2 promoter region has been commonly used for a Ca2+-response reporter gene system, but requirement of concomitant activation of AP-1 (Fos/Jun) often complicates the interpretation of obtained results. A new nanoluciferase (NanoLuc) reporter gene containing nine-tandem repeats of a pseudo-palindromic NFAT-RE located upstream of the IL8 promoter was designed to monitor Ca2+-induced transactivation activity of NFAT in human embryonic kidney (HEK) 293 cells by measuring luciferase activities of NanoLuc and co-expressed firefly luciferase for normalization. Ionomycin treatment enhanced the relative luciferase activity (RLA), which was suppressed by calcineurin inhibitors. HEK293 cells that stably express human STIM1 and Orai1, components of the store-operated calcium entry (SOCE) machinery, gave a much higher RLA by stimulation with thapsigargin, an inhibitor of sarcoplasmic/endoplamic reticulum Ca2+-ATPase (SERCA). HEK293 cells deficient in a penta-EF-hand Ca2+-binding protein ALG-2 showed a higher RLA value than the parental cells by stimulation with an acetylcholine receptor agonist carbachol. The novel reporter gene system is found to be useful for applications to cell signaling research to monitor biological endpoint effects of cellular Ca2+ mobilization.

    Mobilization of intracellular calcium is essential for a wide range of cellular processes, including signal transduction, apoptosis, and vesicular trafficking. Several lines of evidence have suggested that apoptosis-linked gene 2 (ALG-2, also known as PDCD6), a calcium-binding protein, acts as a calcium sensor linking calcium levels with efficient vesicular trafficking, especially at the endoplasmic reticulum (ER)-to-Golgi transport step. However, how ALG-2 regulates these processes remains largely unclear. Here, we report that MAPK1-interacting and spindle-stabilizing (MISS)-like (MISSL), a previously uncharacterized protein, interacts with ALG-2 in a calcium-dependent manner. Live-cell imaging revealed that upon a rise in intracellular calcium levels, GFP-tagged MISSL (GFP-MISSL) dynamically relocalizes in a punctate pattern and colocalizes with ALG-2. MISSL knockdown caused disorganization of the components of the ER exit site, the ER-Golgi intermediate compartment, and Golgi. Importantly, knockdown of either MISSL or ALG-2 attenuated the secretion of secreted alkaline phosphatase (SEAP), a model secreted cargo protein, with similar reductions in secretion by single- and double-protein knockdowns, suggesting that MISSL and ALG-2 act in the same pathway to regulate the secretion process. Furthermore, ALG-2 or MISSL knockdown delayed ER-to-Golgi transport of procollagen type I. We also found that ALG-2 and MISSL interact with microtubule-associated protein 1B (MAP1B) and that MAP1B knockdown reverts the reduced secretion of SEAP caused by MISSL or ALG-2 depletion. These results suggest that a change in the intracellular calcium level plays a role in regulation of the secretory pathway via interaction of ALG-2 with MISSL and MAP1B.

    Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder. We screened 751 familial ALS patient whole-exome sequences and identified six mutations including p.D40G in the ANXA11 gene in 13 individuals. The p.D40G mutation was absent from 70,000 control whole-exome sequences. This mutation segregated with disease in two kindreds and was present in another two unrelated cases (P = 0.0102), and all mutation carriers shared a common founder haplotype. Annexin A11-positive protein aggregates were abundant in spinal cord motor neurons and hippocampal neuronal axons in an ALS patient carrying the p.D40G mutation. Transfected human embryonic kidney cells expressing ANXA11 with the p.D40G mutation and other N-terminal mutations showed altered binding to calcyclin, and the p.R235Q mutant protein formed insoluble aggregates. We conclude that mutations in ANXA11 are associated with ALS and implicate defective intracellular protein trafficking in disease pathogenesis.

    Apoptosis-linked gene 2 (ALG-2), which is a gene product of PDCD6, is a 22-kDa Ca2+ -binding protein. Accumulating evidence points to a role for ALG-2 as a Ca2+ -responsive adaptor protein. On binding to Ca2+ , ALG-2 undergoes a conformational change that facilitates its interaction with various proteins. It also forms a homodimer and heterodimer with peflin, a paralog of ALG-2. However, the differences in cellular roles for the ALG-2 homodimer and ALG-2/peflin heterodimer are unclear. In the present study, we found that Trk-fused gene (TFG) protein interacted with the ALG-2 homodimer. Immunostaining analysis revealed that TFG and ALG-2 partially overlapped at endoplasmic reticulum exit sites (ERES), a platform for COPII-mediated protein transport from the endoplasmic reticulum. Time-lapse live-cell imaging demonstrated that both green fluorescent protein-fused TFG and mCherry-fused ALG-2 are recruited to ERES after thapsigargin treatment, which raises intracellular Ca2+ levels. Furthermore, overexpression of ALG-2 induced the accumulation of TFG at ERES. TFG has an ALG-2-binding motif and deletion of the motif decreased TFG binding to ALG-2 and shortened its half-life at ERES, suggesting a critical role for ALG-2 in retaining TFG at ERES. We also demonstrated, by in vitro cross-linking assays, that ALG-2 promoted the polymerization of TFG in a Ca2+ -dependent manner. Collectively, the results suggest that ALG-2 acts as a Ca2+ -sensitive adaptor to concentrate and polymerize TFG at ERES, supporting a potential role for ALG-2 in COPII-dependent trafficking from the endoplasmic reticulum.

    ALG-2, a member of the penta-EF-hand protein family, interacts Ca²+-dependently with a COPII component, Sec31A. In this study, we first established HeLa cells stably expressing green fluorescent protein-fused ALG-2 (GFP-ALG-2) and red fluorescent protein-fused Sec31A (Sec31A-RFP). After inducing Ca²+-mobilization, the cytoplasmic distribution of GFP-ALG-2 changed from a diffuse to a punctate pattern, which extensively overlapped with the Sec31A-RFP-positive structures, indicating that ALG-2 is recruited to the endoplasmic reticulum exit sites (ERES) in living cells. Next, overlay experiments with biotin-labeled ALG-2 were done to dissect the ALG-2 binding site (ABS). They revealed that a sequence comprising amino acid residues 839-851 in the Pro-rich region was necessary and sufficient for direct binding to ALG-2. Finally, fluorescence recovery after photobleaching analysis indicated that the ABS deletion reduced the high-affinity population of Sec31A to the ERES, suggesting that the ABS is one of the key determinants of the retention kinetics of Sec31A at ERES.

    損傷したリソソームからは加水分解酵素や水素イオン、カルシウムイオンなどが漏出するため、細胞は損傷リソソームの迅速な修復および修復不能な損傷リソソームの除去とリソソームの再生機能を有する。しかし、これらの細胞応答を惹起する分子メカニズムの全容は明らかとされていない。本研究では、損傷リソソームから漏出するカルシウムイオンに応答し、損傷部位に動員されるカルシウム結合蛋白質に着目し、それらと協調して機能する蛋白質の同定とリソソーム損傷を起点とする細胞応答における役割の解明を目指す。本研究成果は、リソソーム損傷を原因とする疾患の発症予防と病態進行緩和の創薬シーズの発見につながることが期待される。
    リソソームは細胞内消化を担う膜で覆われた細胞小器官である。限界膜が損傷したリソソームからは、加水分解酵素や水素イオン、カルシウムイオンなどが漏出する。研究代表者らは、損傷したリソソームにカルシウム結合蛋白質ALG-2が動員される現象を見出しており、リソソームの損傷を誘発した細胞においてALG-2の近傍に存在する蛋白質を同定している。本年度は、その中でLIP5に着目し以下を解析した。
    (1) LIP5の免疫染色実験により、LIP5がリソソーム損傷を誘導した細胞でリソソームに動員されることを観察した。LIP5のリソソーム動員におけるカルシウムイオンの役割を明らかにする目的で、カルシウムキレータであるBAPTA-AMを処理したところ、LIP5のリソソーム動員が抑制された。一方、ALG-2のノックアウト細胞でもリソソーム損傷刺激後のLIP5のリソソーム局在が観察された。
    (2) LIP5の発現抑制がその相互作用蛋白質であるVPS4A/Bの損傷リソソームへの局在に与える影響を解析した。VPS4A/Bはリソソーム損傷刺激を加えた細胞においてリソソームに局在したが、LIP5を発現抑制するとリソソーム局在が観察されなかった。
    (3)LIP5発現抑制細胞のリソソーム損傷刺激後の細胞死誘導に関して、ウエスタンブロット解析により発現抑制していない細胞と比較した。その結果、LIP5の発現抑制細胞はリソソーム損傷刺激後にカスパーゼ3/7の基質蛋白質の切断断片が多く検出され、アポトーシスが誘導されていると考えられた。
    リソソーム損傷を誘発した細胞においてALG-2の近傍蛋白質として同定された蛋白質が、カルシウム依存的に損傷リソソームに局在することを明らかにし、国内学会で発表できる成果が得られた。
    LIP5を含めALG-2近傍蛋白質として同定した蛋白質の多くは、カルシウム依存的に損傷リソソームに動員されるものの、ALG-2ノックアウト細胞でもリソソームに動員されることから、ALG-2以外のカルシウム結合蛋白質の関与が予想される。損傷リソソームへの動員が報告されている、また予想されるカルシウム結合蛋白質の発現抑制や阻害剤の添加がLIP5などの損傷リソソーム動員に与える影響を解析する。また、LIP5のリソソーム損傷応答における役割の解明を進める。さらに、筋萎縮性側索硬化症の発症に関連するカルシウム結合蛋白質の変異体の発現がリソソーム損傷応答に与える影響を解析する。

    リソソームは細胞内消化を担う細胞小器官であり、その内腔は酸性で多種の加水分解酵素を含んでいる。リソソーム膜が損傷すると、その内包する加水分解酵素やカルシウムイオンが細胞質に流出することで細胞の恒常性が破綻する。一方で、カルシウムイオンは損傷したリソソーム膜の修復や新生リソソームの合成のための遺伝子発現の引き金を引くことが知られている。本研究では、このカルシウムイオンに応答する細胞質の蛋白質に焦点を当て、その生理機能を解明することで、リソソーム損傷が要因となって発症する疾患の治療法および予防の標的となる蛋白質間相互作用の同定を目指している。

    A characteristic lesion of neurodegenerative diseases is the formation of amyloid fiber-like aggregates, exemplified by TDP-43 in amyotrophic lateral sclerosis (ALS). Aggregates are formed when pathological proteins are seeded and sequester normal cytoplasmic proteins. In this study, cell lines were established that can be monitored the formation of aggregates in the cytoplasm by the ALS-associated mutants of annexin A11 and TDP-43 with mutations in its nuclear localization signal and RNA-binding motifs. Using these cells, the mutant proteins were found to form aggregates triggered by lysosomal damage. On the other hand, these mutants were shown to be rapidly degraded by proteasomes in cells where they did not form aggregates.

    Collagens are structural proteins that constitute approximately 25% of human dry body weight and are secreted from the endoplasmic reticulum to the extracellular space via the Golgi apparatus. In this study, we aimed to elucidate the molecular mechanisms by which calcium-responsive regulators, mainly the calcium-binding protein ALG-2, control export of collagens from the endoplasmic reticulum, by searching for target molecules of ALG-2 by its binding motifs and by using proximity-dependent labeling methods coupled with mass spectrometry. The protein-protein interaction networks and subcellular localization of multiple candidate regulators and their functions were elucidated by biochemical and molecular cell biological approaches.

    Ca2+ is a signaling molecule that plays important roles in eukaryotic cells.In order to investigate the physiological functions of Ca2+-binding protein ALG-2, we searched and identified four new ALG-2-interacting proteins.MISSL accumulates at endoplasmic reticulum (ER) exit sites with ALG-2 upon increase in cytosolic Ca2+ concentrations. It cooperates with microtubule associated protein 1B (MAP1B) to regulate vesicular transport of cargoes from the ER to the Golgi apparatus. ALG-2 binds single-pass ER transmembrane protein named SARAF and suppresses ubiquitination of SARAF. CDIP1 localizes at the endomembrane systems and binds a subset of ESCRT-I proteins in the presence of Ca2+/ALG-2 to promote cell death. We analyzed recruitment of ALG-2 to lysosomes upon impairment of lysosomal membranes. We established a new high sensitive Ca2+-response reporter gene assay system to monitor effects of Ca2+. The system is expected to apply to evaluate food constituents and drugs.

    In mammalian cells, proteins destined for secretion are transported from specialized region of the ER, called ER exit site (ERES), by COPII vesicles. The aim of this study was to investigate the role of ALG-2, a calcium-binding protein, in the regulation of COPII-mediated protein transport. ALG-2 directly interacts with Sec31A, an outer coat component of COPII. Firstly, we identified Trk-fused gene (TFG) product as a novel target for ALG-2. Overexpression of ALG-2 enhanced the localization of TFG to the ERES. Secondly, MISSL was shown to be recruited to the ERES by ALG-2 in response to calcium mobilization. We also found that ALG-2 bridged between MISSL and MAP1B. In our co-immunoprecipitation analysis, TFG, MISSL and MAP1B did not form the complex with Sec31A, suggesting that ALG-2 may have divergent functions at the ERES. Finally, we reported that amyotrophic lateral sclerosis (ALS)-associated mutations in annexin A11 caused abnonormality in binding to S100A6.

    In this study, we sought to clarify the role of Ca2+ in the cellular mechanism of amino acids sensing and the cellular response. Addition of amino acids to the amino acid-starved cell induces the Ca2+ entry from extracellular space, leading to the increase of intracellular Ca2+ concentration. By using the several inhibitors that target particular Ca2+ channels, we identified that Amiloride-sensitive Ca2+ channel appears to responsible for the Ca2+ entry. In addition, we also investigated how increased Ca2+ levels affect the mTORC1, which is a central regulator of amino acid sensing pathway. It is known that amino acids activate mTORC1 via two distinct small GTPases, called Rag GTPases and Rheb GTPase. We found that the action of Rheb GTPase but not Rag was affected by Ca2+. These results suggest a novel regulatory mechanism of mTORC1 through the change of intracellular Ca2+ concentration in response to amino acids.

  8. Mechanism of calcium-response regulation of EF-hand protein ALG-2 in the nucleus and membranes

    　 More details

    In the early secretory pathway of proteins from the endoplasmic reticulum to the Golgi apparatus, Ca2+-dependent accumulation of ALG-2 to the endoplasmic reticulum exit sites bridges Sec31A, a component of COPII outer shell, and annexin A11 and retards transport of a model cargo membrane protein, and causes multimerization of the TFG protein. Refinement of the binding sequences by the X-ray crystal structural analysis of ALG-2 and the Sec31A peptide and by mutational analysis of both proteins, we propose a new ALG-2-binding motif. We searched proteins containing the motif and found a novel ALG-2 interacting proteins that passes through the ER membrane. ALG-2 was found to inhibit the activity of the Ca2+-dependent transcription factor NFAT.
