Inhibition of chicken calpain II by proteins of the cystatin superfamily and alpha 2-macroglobulin was investigated. Human liver cystatins A and B, human cystatin C, chicken cystatin and rat T-kininogen were found not to be inhibitory. Inhibition was, however, observed

Homogeneous porcine calpain (Ca2+-dependent cysteine proteinase) was found to hydrolyze a variety of peptides and synthetic substrates. Leu-Trp-Met-Arg-Phe-Ala, eledoisin-related peptide, alpha-neoendorphin, angiotensin I, luteinizing hormone-releasing hormone, neurotensin, dynorphin, glucagon, and oxidized insulin B chain were cleaved with a general preference

Detecting calpain activity in Drosophila tissues is a fundamental tool to study calpain function. We use differential centrifugation to prepare membrane- versus cytosol-enriched fractions for measuring calpain activity with the fluorogenic substrate N-LY-AMC. With this method one can measure calpain
