3.4.22.52 | Ca2+ |
dependent on (0.002-0.02 mM). At resting [Ca2+], mu-calpain is present predominantly in its full-length, unautolysed/unactivated forms. Once activated, mu-calpain appears in its autolysed form. Endogenously expressed mu-calpain is activated within a physiological [Ca2+] range in a Ca2+- and time-dependent manner. Autolysed mu-calpain isoforms have a greater Ca2+ sensitivity than the full-length 80000 Da isoform |

3.4.22.52 | Ca2+ |
dependent on, 100% activity at concentrations higher than 0.04 mM |
732676 |
3.4.22.52 | Ca2+ |
dependent on, dysfunctional mitochondria increase cytosolic calcium, thereby inducing calpain activation |
710069 |
3.4.22.52 | Ca2+ |
dimeric calpain I requires 0.002 mM for half-maximal activation and 0.01 mM for maximal activation. The 70000 Da monomeric calpain I requires only 0.001 mM Ca2+ for half-maximal activity |
