記述言語：日本語

In gametes, embryos, and neural cells, huge glycans with >10 kDa are often attached on glycoconjugates. Of those, the polysialic acid (polySia) modifies the neural cell adhesion molecules and other particular proteins, playing multiple roles in regulation of cell surface phenomena. Underlying mechanisms for the polySia-related functions are twofold. One is due to structural diversity of polySia arisen from differences in the Sia species, the inter-residue linkage, and the degree of polymerization (DP). Significance of the DP has been clarified, and not only lectins but also physiologically active molecules recognize the polymerized structures of Sia in a DP-dependent manner to trigger the different downstream signals. The other is based on the repulsive and attractive interactions of polySia with polySia itself and other binding counterpart molecules including BDNF and FGF2. Here we show that, as a code for cell surface event, the polymerized structures of Sia are expressed and interacted with various decoders, such as Siglecs, BDNF, FGF2, and dopamine, which specifically bind each of their diverse structures, diSia, triSia, oligoSia and polySia. Especially, polySia is shown to display repulsive and attractive fields at the same time to implement integrated functions of various related physiologically active molecules.

ST8 alpha-N-acetyl-neuraminide alpha- 2,8-sialyltransferase 2 (ST8SIA2)

Sato C.

Handbook of Glycosyltransferases and Related Genes, Second Edition 2014年1月（ ISBN:9784431542407, 9784431542391 ）

記述言語：日本語

ST8 α-N-acetyl-neuraminide α-2,8-sialyltransferase 2 (ST8SIA2) is a member of a family of α2,8-sialyltransferases that transfer sialic acid from CMP-sialic acid onto sialic acid residues of other sialoglycans to generate α2,8-linked sialoglycans. ST8SIA2 is characterized by the ability to synthesize polysialic acid (polySia) structure and can therefore be subclassified as a polysialyltransferase. Both ST8SIA2 and the related polysialyltransferase ST8SIA4 (refer to the Chap. ST8SIA4) are capable of synthesizing extraordinary long polySia chains with degrees of polymerization (DP) of up to 400. ST8SIA2 is a type II transmembrane protein, similar to many other glycosyltransferases, and is composed of 375 amino acids with six N-glycans. This enzyme contains sialyl-motif (SM) L, S, VS, and III domains.

Polysialic acid

Sato C.

Sialobiology: Structure, Biosynthesis and Function. Sialic Acid Glycoconjugates in Health and Disease 2013年8月（ ISBN:9781608050673 ）

記述言語：日本語

Sialic acids (Sia) are involved in many biological activities and are commonly present as monosialyl residues at the non-reducing terminal end of glycoconjugates. Occasionally, polymerized structures in the form of disialic acid (diSia), oligosialic acid (oligoSia), and polysialic acid (polySia) appear in glycoconjugates. In particular, polySia is known to be a common epitope from bacteria to humans and is one of the most famous, biologically-important glycotopes in vertebrates. The biological functions of polySia, especially on neural cell adhesion molecules (NCAMs), have been well studied and an indepth body of knowledge concerning polySia has been accumulated. However, considerably less attention has been paid to glycoproteins containing di- and oligoSia groups. As the analytical methods used to detect oligo/polymerized structures have been improved, glycoproteins containing di/oligo/polySia chains have been identified with an increasing frequency in nature. In addition, more sophisticated genetic techniques have helped elucidate the underlying mechanisms of polySia-mediated activities. In this chapter, the recent advances in the study of di-, oligo- and polySia residues on glycoproteins, including their distribution, chemical properties, biosynthetic pathways, and functions are described. © 2013 Bentham Science Publishers.
