Summaries for ST8SIA2 Gene

Entrez Gene Summary for ST8SIA2 Gene

  • The protein encoded by this gene is a type II membrane protein that is thought to catalyze the transfer of sialic acid from CMP-sialic acid to N-linked oligosaccharides and glycoproteins. The encoded protein may be found in the Golgi apparatus and may be involved in the production of polysialic acid, a modulator of the adhesive properties of neural cell adhesion molecule (NCAM1). This protein is a member of glycosyltransferase family 29. [provided by RefSeq, Jul 2008]

GeneCards Summary for ST8SIA2 Gene

ST8SIA2 (ST8 Alpha-N-Acetyl-Neuraminide Alpha-2,8-Sialyltransferase 2) is a Protein Coding gene. Diseases associated with ST8SIA2 include spastic ataxia, charlevoix-saguenay type and acute diarrhea. Among its related pathways are Transport to the Golgi and subsequent modification and Developmental Biology. GO annotations related to this gene include sialyltransferase activity and alpha-N-acetylneuraminate alpha-2,8-sialyltransferase activity. An important paralog of this gene is ST8SIA1.
