Summaries for ST3GAL5 Gene

Entrez Gene Summary for ST3GAL5 Gene

  • Ganglioside GM3 is known to participate in the induction of cell differentiation, modulation of cell proliferation, maintenance of fibroblast morphology, signal transduction, and integrin-mediated cell adhesion. The protein encoded by this gene is a type II membrane protein which catalyzes the formation of GM3 using lactosylceramide as the substrate. The encoded protein is a member of glycosyltransferase family 29 and may be localized to the Golgi apparatus. Mutation in this gene has been associated with Amish infantile epilepsy syndrome. Transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for ST3GAL5 Gene

ST3GAL5 (ST3 Beta-Galactoside Alpha-2,3-Sialyltransferase 5) is a Protein Coding gene. Diseases associated with ST3GAL5 include Amish Infantile Epilepsy Syndrome and Epilepsy Syndrome. Among its related pathways are Glycosphingolipid biosynthesis - ganglio series and Transport to the Golgi and subsequent modification. GO annotations related to this gene include sialyltransferase activity and lactosylceramide alpha-2,3-sialyltransferase activity. An important paralog of this gene is ST3GAL4.
