Calpain-1 is a ubiquitous calcium dependent cysteine protease and found in cytoplasm as well as mitochondria. We have earlier reported that active calpain-1 is translocated from cytosol to mitochondria and activates MMP9. Calpain-1 activation is detrimental to the heart in several different ways, but there is little evidence that it can degrade Purkinje cell protein (PCP-4) and impair contractility in diabetes. Our hypothesis is that in diabetes, PCP-4 is degraded by calpain-1, causing contractile dysfunction that can be mitigated by
