Summaries for CAPN5 Gene

Entrez Gene Summary for CAPN5 Gene

  • Calpains are calcium-dependent cysteine proteases involved in signal transduction in a variety of cellular processes. A functional calpain protein consists of an invariant small subunit and 1 of a family of large subunits. CAPN5 is one of the large subunits. Unlike some of the calpains, CAPN5 and CAPN6 lack a calmodulin-like domain IV. Because of the significant similarity to Caenorhabditis elegans sex determination gene tra-3, CAPN5 is also called as HTRA3. [provided by RefSeq, Jul 2008]

GeneCards Summary for CAPN5 Gene

CAPN5 (Calpain 5) is a Protein Coding gene. Diseases associated with CAPN5 include vitreoretinopathy, neovascular inflammatory. Among its related pathways are ERK Signaling and Apoptosis Pathway. GO annotations related to this gene include calcium-dependent cysteine-type endopeptidase activity. An important paralog of this gene is CAPN9.

Tocris Summary for CAPN5 Gene

  • Calpains are a group of calcium-sensitive cysteine proteases that are ubiquitously expressed in mammals. This family contains 14 members with mu-calpain (calpain 1) and m-calpain (calpain 2) being the most well-characterized. Structurally, calpains contain two subunits; an 80 kDa catalytic subunit and a 28 kDa regulatory subunit that functions as a chaperone to stabilize the 80 kDa structure. Calpains are regulated by Ca2+ concentration, phosphorylation, calpastatin and probably by altering their subcellular localization (limiting access to substrate). These endopeptidases have numerous functions including, but not limited to, remodeling of cytoskeletal attachments to the plasma membrane during cell fusion and cell motility, proteolytic modification of molecules in signal transduction pathways, degradation of enzymes controlling progression through the cell cycle, regulation of gene expression, substrate degradation in some apoptotic pathways, and an involvement in long-term potentiation. Perturbations in calpain activity have been associated in pathophysiological processes contributing to type II diabetes (calpain 10), Alzheimer's disease (calpain 1), gastric cancer (calpain 9) and muscular dystrophy (calpain 3).

  • Vitreoretinopathy, neovascular inflammatory (VRNI) [MIM:193235]: An autoimmune condition of the eye that sequentially mimics uveitis, retinitis pigmentosa, and proliferative diabetic retinopathy as it progresses to complete blindness. Patients present during the second or third decade of life with posterior uveitis and reduction of the electroretinogram b-wave. They become more symptomatic when cataracts, cystoid macular edema, and disk edema diminish visual acuity during the second stage. Severe vision loss begins during the third stage when proliferative retinal neovascularization and epiretinal membranes appear. There is an ongoing pigmentary retinal degeneration and peripheral visual field loss during all stages. In the fourth stage, proliferative vitreoretinopathy causes tractional retinal detachments at the macula and vitreous base. The fifth or end-stage disease is marked by phthisis. {ECO:0000269 PubMed:23055945}. Note=The disease is caused by mutations affecting the gene represented in this entry.
