One substrate, Junctophilin-2 (JP2), is essential for maintaining junctional cardiac dyads and excitation-contraction coupling.

WebCalpains are intracellular Ca (2+)-regulated cysteine proteases that are essential for various cellular functions. Mammalian conventional calpains (calpain-1 and calpain-2) modulate the structure and function of their substrates by limited proteolysis. Thus, it is critically important to determine the site (s) in proteins at which calpains cleave. WebJul 19, 2016 · Calpain (EC 3.4.22.17, Clan CA, family C02) has a substrate specificity that is relatively restricted, and most of oligopeptides are not efficiently hydrolyzed. Casein is the most popular substrate for in vitro assays, and it is used either as the natural protein or modified with various chromophores, fluorescent reagents or isotopes.
