| 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. |
| 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. |
| Top Pathways | Mucin type O-Glycan biosynthesis, Glycosaminoglycan biosynthesis - keratan sulfate, Glycosphingolipid biosynthesis - globo series, Glycosphingolipid biosynthesis - ganglio series |
