Protein Structure
UniProt Annotation
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 Localization 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.
Disease Associations
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.
