UNC13B - unc-13 homolog B Gene
Also Known as UNC13; MUNC13; Unc13h2; munc13-2
Species: Homo sapiens
About UNC13B
This gene has 10 transcripts (splice variants), 200 orthologues and 2 paralogues. Broad expression in lung (RPKM 12.8), kidney (RPKM 6.6) and 23 other tissues.
Summary
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]
