SIA7D rabbit pAb

catalytic activity:CMP-N-acetylneuraminate + N-acetyl-alpha-neuraminyl-(2->3)-beta-D-galactosyl-(1->3)-N-acetyl-D-galactosaminyl-R = CMP + N-acetyl-alpha-neuraminyl-(2->3)-beta-D-galactosyl-(1->3)-(N-acetyl-alpha-neuraminyl-(2->6))-N-acetyl-D-galactosaminyl-R.,function:Involved in the biosynthesis of ganglioside GD1A from GM1B. Transfers CMP-NeuAc with an alpha-2,6-linkage to GalNAc residue on NeuAc-alpha-2,3-Gal-beta-1,3-GalNAc of glycoproteins and glycolipids. Prefers glycoproteins to glycolipids.,online information:GlycoGene database,online information:ST6GalNAc IV,pathway:Protein modification; protein glycosylation.,similarity:Belongs to the glycosyltransferase 29 family.,tissue specificity:Ubiquitous.,
