GKFSGFAKILKSIAKFFKGVGKVRKQFKEASDLDKNQ - Function:Disrupts biological membranes, particularly those rich in phosphocholine. Has antimicrobial activity against Gram-negative bacterium E.coli, Gram-positive bacteria B.subtilis and S.aureus, and hemolytic activity against sheep, pig and guinea pig red blood cells. Has insecticidal activity against S.frugiperda ovarian cells by opening non-selective ion channels. Enhances the insecticidal activity of spider venom neurotoxic peptides.
