CC   -!- FUNCTION: A beta-galactoside alpha2-3 sialyltransferase primarily
CC       involved in terminal sialylation of ganglio and globo series
CC       glycolipids (PubMed:8920913, PubMed:9266697). Catalyzes the transfer of
CC       sialic acid (N-acetyl-neuraminic acid; Neu5Ac) from the nucleotide
CC       sugar donor CMP-Neu5Ac onto acceptor Galbeta-(1->3)-GalNAc-terminated
CC       glycoconjugates through an alpha2-3 linkage (PubMed:8920913,
CC       PubMed:9266697, PubMed:25916169). Sialylates GM1/GM1a, GA1/asialo-GM1
CC       and GD1b gangliosides to form GD1a, GM1b and GT1b, respectively
CC       (PubMed:8920913, PubMed:9266697). Together with ST3GAL3, primarily
CC       responsible for biosynthesis of brain GD1a and GT1b that function as
CC       ligands for myelin-associated glycoprotein MAG on axons, regulating MAG
CC       expression and axonal myelin stability and regeneration (By
CC       similarity). Via GT1b regulates TLR2 signaling in spinal cord microglia
CC       in response to nerve injury (By similarity). Responsible for the
CC       sialylation of the pluripotent stem cell- and cancer stem cell-
CC       associated antigen SSEA3, forming SSEA4 (PubMed:12716912). Sialylates
CC       with low efficiency asialofetuin, presumably onto O-glycosidically
CC       linked Galbeta-(1->3)-GalNAc-O-Ser (PubMed:9266697, PubMed:25916169).
