1.MECHANISM OF ACTION

Mastoparan functions primarily through its amphipathic α-helical structure that enables interaction with cell membranes and G-protein coupled receptors (GPCRs). The peptide inserts into lipid bilayers, forming transient pores and increasing membrane permeability. More significantly, Mastoparan directly activates heterotrimeric G proteins (particularly Gi/Go subtypes) by mimicking the intracellular loop of activated GPCRs, leading to GDP-GTP exchange and downstream signaling activation. This G-protein activation occurs independently of receptor engagement, making it a valuable tool for studying G-protein signaling pathways. Additionally, Mastoparan can stimulate phospholipase C activity, modulate ion channels, and induce calcium influx, contributing to its diverse biological effects including mast cell degranulation, hormone secretion, and antimicrobial activity through membrane disruption.
