| 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 {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. Secreted {ECO:0000250}. Note=Membrane-bound form in trans cisternae of Golgi. Secreted into the body fluid (By similarity). {ECO:0000250}.
|
| Tissue Specificity |
Highly expressed in skeletal muscle and heart and to a much lesser extent in brain, placenta, liver and pancreas. Scarcely detectable in lung and kidney. {ECO:0000269|PubMed:8920913, ECO:0000269|PubMed:9266697}.
