Comments

Comment Type Description
Catalytic Activity CMP-N-acetylneuraminate + beta-D-galactosyl- 1,3-N-acetyl-alpha-D-galactosaminyl-R = CMP + alpha-N- acetylneuraminyl-2,3-beta-D-galactosyl-1,3-N-acetyl-alpha-D- galactosaminyl-R.
Function It may be responsible for the synthesis of the sequence NeuAc-alpha-2,3-Gal-beta-1,3-GalNAc- found in terminal carbohydrate groups of certain glycoproteins, oligosaccharides and glycolipids. SIAT4A and SIAT4B sialylate the same acceptor substrates but exhibit different Km values.
Pathway Protein modification; protein glycosylation.
Ptm The soluble form derives from the membrane form by proteolytic processing.
Similarity Belongs to the glycosyltransferase 29 family. {ECO:0000305}.
Subcellular Location Golgi apparatus, Golgi stack membrane; Single-pass type II membrane protein. Secreted. Note=Membrane- bound form in trans cisternae of Golgi. Secreted into the body fluid.
Tissue Specificity Strongly expressed in brain and liver and to a lesser extent in heart and kidney. Scarcely detectable in lung, pancreas, spleen and submaxillary gland.
