alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase 3 isoform 8 [Homo sapiens]

Protein Classification

glycosyltransferase family 29 protein( domain architecture ID 690)

glycosyltransferase family 29 protein catalyzes the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds; uses a nucleotide monophosphosugar as the donor (CMP-NeuA) instead of a nucleotide diphosphosugar

alpha-N-acetylneuraminide alpha-2,8-sialyltransferase 4; ST8Sia4 is a polysialyltransferase that can synthesize polysialic acid on neural cell adhesion molecules (NCAMs). ST8Sia4 catalyzes longer polysialicacid formation of NCAMs than ST8Sia2. ST8Sia family members are alpha-N-acetylneuraminide alpha-2,8-sialyltransferases that catalyze an alpha-2,8-linkage between sialic acid and the terminal sialic acid residues of glycochains, by transfering sialic acid from CMP-Sia and they belong to the glycosyltransferase family 29 (GT29).

alpha-N-acetylneuraminide alpha-2,8-sialyltransferase 1; Alpha-N-acetylneuraminide alpha-2,8-sialyltransferase 1 (also known as ganglioside GD3 synthase) adds sialic acids to GM3 ganglioside. ST8Sia family members are alpha-N-acetylneuraminide alpha-2,8-sialyltransferases that catalyze analpha-2,8-linkage between sialic acid and the terminal sialic acid residues of glycochains, by transfering sialic acid from CMP-Sia. The ST8Sia family belongs to the glycosyltransferase family 29 (GT29).

alpha-N-acetylneuraminide alpha-2,8-sialyltransferase 6; alpha-N-acetylneuraminide alpha-2,8-sialyltransferase 6 (also known as alpha-2,8-sialyltransferase 8F) prefers O-glycans to N-glycans or glycolipids as acceptor substrates. ST8Sia family members are alpha-N-acetylneuraminide alpha-2,8-sialyltransferases that catalyze an alpha-2,8-linkage between sialic acid and the terminal sialic acid residues of glycochains, by transfering sialic acid from CMP-Sia. The ST8Sia family belongs to glycosyltransferase family 29(GT29).
