Product Description
The calpain (calcium-dependent protease or calcium-activated neutral protease) system consists of two ubiquitous forms of calpain (µ-calpain and m-calpain), a tissue specific calpain (n-calpain), and a calpain inhibitory protein (calpastatin). The calpain system has been detected in every vertebrate tissue examined, and has been suggested to play a regulatory role in cellular protein metabolism. This regulatory role may have important implications in platelet aggregation and pathologies associated with altered calcium homeostasis and protein metabolism such as ischemic cell injury and degenerative diseases. Inhibitors of calpain have been shown to block dexamethasone and low-level irradiation induced apoptosis in thymocytes suggesting that calpain has a regulatory or mechanistic role in apoptotic cell death.
µ- and m-calpains are heterodimers consisting of 28 kDa and 80 kDa subunits. The 28 kDa subunit is identical in the two isoforms, but the 80 kDa subunits differ with ~50% sequence similarity. 28 kDa/80 kDa complexes are thought to be inactive proenzymes which, upon binding of calcium, undergo conformational changes that promotes cleavage of the 28 kDa subunit and results in enzyme activation.
