|
| Function |
It may be responsible for the synthesis of the sequence NeuAc-alpha-2,3-Gal-beta-1,3-GalNAc- found on sugar chains O- linked to Thr or Ser and also as a terminal sequence on certain gangliosides. 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 |
Highly expressed in submaxillary gland and to a much lesser extent in liver, lung, kidney, heart and brain.
