Summaries for SYT8 Gene

Entrez Gene Summary for SYT8 Gene

  • This gene encodes a member of the synaptotagmin protein family. Synaptotagmins are membrane proteins that are important in neurotransmission and hormone secretion, both of which involve regulated exocytosis. Expression of the encoded protein in human pancreatic islets has been connected to activity of the promoter for the insulin gene, on the same chromosome several hundred kilobases away (PMID: 21336277 and 22928559). This association would link response to gluclose to insulin secretion. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2014]

GeneCards Summary for SYT8 Gene

SYT8 (Synaptotagmin 8) is a Protein Coding gene. GO annotations related to this gene include calcium ion binding and syntaxin binding. An important paralog of this gene is SYT5.

UniProtKB/Swiss-Prot for SYT8 Gene

  • Isoform 4 may play a role in the trafficking and exocytosis of secretory vesicles in non-neuronal tissues. Mediates Ca(2+)-regulation of exocytosis acrosomal reaction in sperm. May mediate Ca(2+)-regulation of exocytosis in insulin secreted cells (By similarity).
