Primary antibody notes
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. Calpastatin, a specific endogenous inhibitor of calpain, has a predicted molecular weight of ~77 kDa and an internal repeat of four homologous domains which allow it to inhibit multiple calpain molecules simultaneously. It functions by binding to calpain when calpain binds calcium. When calpastatin is subjected to proteolytic digestion, fragments of calpastatin as small as 15 kDa still retain inhibitory activity.

WB
ICC
Application notes
ICC: 1/200.
WB: 1/5000. Detects bands of approximately 150, 125, 90 and 70 kDa (predicted molecular weight: 85 kDa) proteins from bovine skeletal muscle extract, which have been suggested to be proteins translated from different start sites of the calpastatin gene.
Immunocytochemical staining of calpastatin in porcine LLC-PK1 cells with ab5582 results in diffuse cytoplasmic staining.
Not tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
Target
Function
Specific inhibition of calpain (calcium-dependent cysteine protease). Plays a key role in postmortem tenderization of meat and have been proposed to be involved in muscle protein degradation in living tissue.
Sequence similarities
Belongs to the protease inhibitor I27 (calpastatin) family.
Domain
Has four inhibitory domains.
Post-translational
modifications
The N-terminus is blocked.
