Amino Acid Sequence

Ile-Asn-Leu-Lys-Ala-Leu-Ala-Ala-Leu-Ala-Lys-Lys-Ile-Leu-NH2

Description générale

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.

Actions biochimiques/physiologiques

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