3.4.22.52 2-mercaptoethanol required for maximal activity 643967 3.4.22.52 angiotensin II 1.2-fold increased activity of calpain-1, influence in expression of calpain-1 700880 3.4.22.52 Ca2+ required for activation of mu-calpain. Membrane-binding of mu-calpain is Ca2+-dependent. Membrane binding of mu-calpain is due to the exposed hydrophobic surface of the active site conformation and does not reduce the Ca2+ requirement for activation 667872 3.4.22.52 endotoxin treatment with 12 mg/kg endotoxin increases diaphragm calpain activity and active calpain I protein 707082 3.4.22.52 additional information HRSP12 (UK114) stimulates the hydrolysis activity of Calpain1 717053 3.4.22.52 additional information no influence on expression of calpain-1 by mechanical stimulation 697162 3.4.22.52 NS5A protein the nonstructural hepatitis C virus protein NS5Ais sufficient to activate a calpain 1 708643
