Description

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.

Enantiomer-specific bioactivities of peptidomimetic analogues of mastoparan and mitoparan: characterization of inverso mastoparan as a highly efficient cell penetrating peptide.

Sarah Jones et al.

Bioconjugate chemistry, 23(1), 47-56 (2011-12-14)

Retro-inverso transformation has commonly been employed as a strategy both for the synthesis of proteolytically stable peptide analogues and for the detailed investigation of structure activity relationships. Herein, we adopted a similar strategy to probe the structure activity relationships of

Statin drugs inhibit 3-hydroxy-3-methylglutaryl CoA reductase, which reduces the synthesis of both cholesterol and isoprenoids (geranylgeranyl pyrophosphate and farnesyl pyrophosphate), with the latter being lipid molecules responsible for the posttranslational modification of small GTP-binding proteins such as Rho.
