Summaries for SV2B Gene

Entrez Gene Summary for SV2B Gene

  • This gene encodes a member of the synaptic vesicle proteins 2 (SV2) family and major facilitator superfamily of proteins. This protein and other members of the family are localized to synaptic vesicles and may function in the regulation of vesicle trafficking and exocytosis. Studies in mice suggest that the encoded protein may act as a protein receptor for botulinum neurotoxin E in neurons, and that this protein may be important for the integrity of the glomerular filtration barrier. This gene shows reduced expression in areas of synaptic loss in the hippocampus of human temporal lobe epilepsy patients. [provided by RefSeq, Sep 2016]

GeneCards Summary for SV2B Gene

SV2B (Synaptic Vesicle Glycoprotein 2B) is a Protein Coding gene. Diseases associated with SV2B include Prostate Small Cell Carcinoma and Temporal Lobe Epilepsy. Among its related pathways are Toxicity of botulinum toxin type F (BoNT/F) and Uptake and actions of bacterial toxins. Gene Ontology (GO) annotations related to this gene include transporter activity and transmembrane transporter activity. An important paralog of this gene is SV2A.
