睡眠覚醒、体温、ホルモン分泌などの様々な生理活性は、約24時間周期の概日リズムを示すことが知られている。このリズムは生物が昼夜の環境変動に適応するために重要であり、体内時計（概日時計）によって駆動されている。概日時計のリズム発振機構は、概日時計遺伝子産物（概日時計タンパク質）が自身をコードするmRNAの転写を抑制する、転写・翻訳のネガティブフィードバックループモデルにより理解されているが、近年このモデルを支持しない現象も報告されている。またこのモデルは、リズムの周期がなぜ約24時間になるかは十分に説明できない。本研究では定量的な実験と数値解析によりモデルの検証と周期決定機構の解明に取り組む。

For target identification by genetic methods, a genome-wide knockout library was introduced into a human diploid cell line, and the rhythms of approximately 3,000 clones were measured in 384-well plates. As a result, changes in the period and amplitude of the circadian rhythm were observed in about 0.5% of the clones. Using this system, target of the circadian clock-modulating compound can be identified by isolating clones whose response to the compound differs from that of wild-type cells. This screening system can also be used to identify novel circadian clock genes.
By derivatization of picrotoxinin, a compound that shortens the circadian rhythm cycle, we have obtained a compound that shows approximately 1,000-fold higher activity. We are going to perform affinity purification using the new derivative to identify the target.

The widely accepted models for circadian clocks are based on transcriptional-translational negative feedback loops composed of circadian clock genes. However, some important aspects, such as how the periods are adjusted around 24 h and how the phase of the rhythms are determined, are not fully incorporated into these models. On the other hand, there are several examples of protein posttranscriptional modification rhythms independent of the feedback loops, though their exact roles in the circadian clock systems are still unknown. In this study we tried to elucidate these points by proteomic and chemical biology approach. We obtained compounds that affect period and phase and the potential candidates of their target proteins. We also set up the system to study posttranslational modification rhythms including phosphorylation. By these bidirectional approaches, we are now trying to understand the whole circadian clock systems.
