General description

Calpeptin (Z-Leu-nLeu-H) is a cell permeable, peptide aldehyde inhibitor. It is more sensitive to calpain I compared to other inhibitors, such as Z-Leu-Met-H and leupeptin. Calpeptin stimulates neurite elongation in differentiating pheochromocytoma (PC12) cells. Calpeptin decreases microgliosis, astrogliosis, axonal damage and neuron and oligodendrocyte death in experimental autoimmune encephalomyelitis (EAE) spinal cord. Therefore, it can be considered as a potent therapeutic for treating EAE and multiple sclerosis (MS).

Application

Calpeptin has been used as a calpain inhibitor.

Biochem/physiol Actions

Calpeptin is a rho kinase activator and an inhibitor of calpains, a family of calcium-dependent cysteine proteases involved in apoptosis, long-term potentiation in neurons, and cell cycle progression.

The 'phosphate-binding tag' (phos-tag) reagent enables separation of phospho-proteins during SDS-PAGE by impeding migration proportional to their phosphorylation stoichiometry. Western blotting can then be used to detect and quantify the bands corresponding to the phospho-states of a target protein. We
