General description

Mastoparan is a cationic, amphiphilic, tetradecapeptide amide. It is composed of the restricted amino acid and the repeated sequence. This protein is a nonspecific secretagogue isolated from venom of wasp.

Application

Mastoparan has been used as a calmodulin antagonist.

Biochem/physiol Actions

Mastoparan effectively stimulates exocytosis from diverse mammalian cells. The encoded protein facilitates the secretion of histamine from mast cells, serotonin from platelets, catecholamines from chromaffin cells and prolactin from the anterior pituitary. In addition, it is also involved in activation of Phospholipase A2 and phosphoinositides (Pl) break down. Mastoparan functions as an inhibitor for calmodulin-stimulated phosphodiesterase. Mastoparan helps in mitochondrial permeability transition by enhancing an apparent bimodal mechanism of action.

Mast cell degranulating peptide. Activates phospholipase A₂; inhibits calmodulin. Cell permeable; stimulates exocytosis and phosphoinositide breakdown.

Recombinant heterotrimeric G-protein α(i1), α(i2) and α(i3) subunits were purified in GDP-depleting conditions by affinity chromatography using StrepII-tagged β₁γ₂ subunits. Real-time monitoring of fluorescence anisotropy of Bodipy-FL-GTPγS was used for characterization of nucleotide binding properties and inactivation of the purified
