Descripción

General description

Calpeptin inhibits the Ca²⁺-stimulatedcleavage of p35 to p25 by calpain. It regulates the processing of β-amyloidprecursor protein to β-amyloid (Aβ). Calpeptin alleviates neurite elongation indifferentiating PC12 cells. In platelets, it prevents Ca²⁺-ionophore-induceddegradation of actin binding protein and P235. It blocks the myosinlight chain phosphorylation in platelets stimulated by collagen, ionomycin, orthrombin. Calpeptin inhibits the growth of estrogen receptor positive breast cancer cells. Calpeptin is a cell permeable calpain blocker. It also blocks theactivation of T-cells in the immune system. It has been observed that calpeptininduces secondary inflammatory responses and apoptosis in muscle cells.
