Target Details

Target: ST8SIA4 (ST8 alpha-N-Acetyl-Neuraminide alpha-2,8-Sialyltransferase 4 (ST8SIA4))

Alternative Name: ST8SIA4

Background: CMP-N-acetylneuraminate-poly-alpha-2,8-sialyltransferase (EC 2.4.3.-) (Alpha-2,8-sialyltransferase 8D) (Polysialyltransferase) (Polysialyltransferase-1) (Sialyltransferase 8D) (SIAT8-D) (Sialyltransferase St8Sia IV) (ST8SiaIV),FUNCTION: Catalyzes the transfer of a sialic acid from a CMP-linked sialic acid donor onto a terminal alpha-2,3-, alpha-2,6-, or alpha-2,8-linked sialic acid of an N-linked glycan protein acceptor through alpha-2,8-linkages (PubMed:10766765, PubMed:11279095, PubMed:9774483, PubMed:28810663). Therefore, participates in polysialic acid synthesis on various sialylated N-acetyllactosaminyl oligosaccharides, including NCAM1 N-glycans, FETUB N-glycans and AHSG (PubMed:10766765, PubMed:11279095, PubMed:9774483, PubMed:28810663). It is noteworthy that alpha-2,3-linked sialic acid is apparently a better acceptor than alpha-2,6-linked sialic acid (PubMed:9774483). {ECO:0000269|PubMed:10766765, ECO:0000269|PubMed:11279095, ECO:0000269|PubMed:28810663, ECO:0000269|PubMed:9774483}.
