一般說明
Calpain-1 catalytic subunit is a protein encoded by the CAPN1 gene in humans. Calpains are calcium dependent proteases constituting a family of proteins. They share a homologous cysteine-protease domain and an E-F hand Ca2+-binding domain. The calpain system consists of two ubiquitous forms of calpain (m-calpain and μ-calpain), a tissue specific calpain (n-calpain) and a calpain inhibitory protein (calpastatin).
特異性
Epitope mapping studies indicate the epitope is between amino acids 245-265 (domain II) of human μ-calpain. The antibody reacts specifically with μ-calpain. It does not cross-react with m-calpain, n-calpain, calmodulin or calpastatin. It is not recommended for immunoprecipitation. By immunoblotting, reactivity is observed with human platelets and erythrocytes, bovine platelets, heart and skeletal muscle and with rat myoblasts, kidney, liver and spleen. By immunofluorescence on pig LLC-PK1 cells, diffuse cytoplasmic staining is observed.
免疫原
μ-calpain from bovine skeletal muscle.
應用
Monoclonal Anti-μ-Calpain (Domain II) antibody produced in mouse is suitable for indirect immunofluorescence at a dilution of 1:25 and western blotting at a dilution of 1:1000.
生化／生理作用
Calpain is involved in calmodulin-independent pathway for the activation of calcineurin. Endogenous calpain I forms active calcineurin in the human heart by proteolysis of calcineurin A, which may lead to pathogenesis of myocardial disease. μ-calpain, on overexpression, may have relationship with intractable epilepsy as well as the clinicopathological characteristics in such patients. Its activity may increase in skeletal muscle of gastric cancer patients.

Limited proteolysis by calpain (Ca(2+)-activated protease; EC 3.4.22.17) is believed to regulate the function of membrane enzymes and modify the behavior of membrane structural proteins. Calpain is activated by autolysis. The degradation of band 3 protein by mu-calpain is known

Proteolytic degradation of numerous calpain substrates, including cytoskeletal and regulatory proteins, has been observed during brain ischemia and reperfusion. In addition, calpain inhibitors have been shown to decrease degradation of these proteins and decrease postischemic neuronal death. Although these observations
