Insecticidal, cytolytic and antimicrobial peptide. Has insecticidal activity against the flesh fly S.carnaria. Has antibacterial activity against the Gram-negative bacteria E.coli. Forms voltage-dependent, ion-permeable channels in membranes. At high concentration causes cell membrane lysis. Expressed by the venom gland. Both the N-terminus (61-94) and the C-terminus (99-129) of the mature peptide form alpha-helices which probably disrupt target cell membranes. The linker region (95-98) probably derives from a processing quadruplet motif (PQM), found in propeptides of many zodatoxins, hinting at a fusion of two originally separate membrane-active peptides. Cleavage of the propeptide depends on the processing quadruplet motif (XXXR, with at least one of X being E). Belongs to the cationic peptide 06 (cytoinsectotoxin) family.
