Summaries for UNC13B Gene

Entrez Gene Summary for UNC13B Gene

  • This gene is expressed in the kidney cortical epithelial cells and is upregulated by hyperglycemia. The encoded protein shares a high level of similarity to the rat homolog, and contains 3 C2 domains and a diacylglycerol-binding C1 domain. Hyperglycemia increases the levels of diacylglycerol, which has been shown to induce apoptosis in cells transfected with this gene and thus contribute to the renal cell complications of hyperglycemia. Studies in other species also indicate a role for this protein in the priming step of synaptic vesicle exocytosis. [provided by RefSeq, Jul 2008]

GeneCards Summary for UNC13B Gene

UNC13B (Unc-13 Homolog B) is a Protein Coding gene. Diseases associated with UNC13B include Hyperglycemia and Masa Syndrome. Among its related pathways are Transmission across Chemical Synapses and Effects of Botulinum toxin. GO annotations related to this gene include signal transducer activity and diacylglycerol binding. An important paralog of this gene is UNC13A.

UniProtKB/Swiss-Prot for UNC13B Gene

  • Plays a role in vesicle maturation during exocytosis as a target of the diacylglycerol second messenger pathway. Is involved in neurotransmitter release by acting in synaptic vesicle priming prior to vesicle fusion and participates in the activity-depending refilling of readily releasable vesicle pool (RRP). Essential for synaptic vesicle maturation in a subset of excitatory/glutamatergic but not inhibitory/GABA-mediated synapses (By similarity).
