Tetrandrine alleviates podocyte injury via calcium-dependent calpain-1 signaling blockade
Background Podocytes have become a crucial target for interventions in proteinuric kidney diseases. Many studies have reported that overexpression of transient receptor potential cation channel protein 6 (TRPC6) in podocyte injury upregulates ...

Proteolysis of mitochondrial calpain-13 in cerebral ischemia-reperfusion injury
Calpains are calcium-dependent cysteine proteases activated by intracellular Ca2+. Although calpains mainly exist in the cytosol, calpain-13 is present in the mitochondria in mouse brains; however, the enzymatic properties and physiological functions of ...

Effect of oxidation, pH, and ionic strength on calpastatin inhibition of μ- and m-calpain [PDF]
The objective of this study was to evaluate the effect of oxidation on μ- and m-calpain activity at varying pH and ionic strength conditions in the presence of calpastatin. In 2 separate experiments, purified porcine skeletal muscle μ- or m-calpain (0.45

Cystatins as calpain inhibitors: Engineered chicken cystatin- and stefin B-kininogen domain 2 hybrids support a cystatin-like mode of interaction with the catalytic subunit of μ-calpain [PDF]
Within the cystatin superfamily, only kininogen domain 2 (KD2) is able to inhibit μ- and m-calpain. In an attempt to elucidate the structural requirements of cystatins for calpain inhibition, we constructed recombinant hybrids of human stefin B (an ...

Increased aortic calpain-1 activity mediates age-associated angiotensin II signaling of vascular smooth muscle cells. [PDF]
Angiotensin II (Ang II) signaling, including matrix metalloproteinase type II (MMP2) activation, has been linked to an age-associated increase in migration capacity of vascular smooth muscle cells (VSMC), and to other proinflammatory features of arterial
