Potent antimicrobial peptide against most of Gram-negative bacteria, some Gram-positive bacteria (Bacillus) and some fungi. Adopts an amphipathic alpha helical conformation, that may allow to partition into the target membrane. No hemolytic and cytotoxic activities have been observed on mammalian cells. Forms a helical membrane channel in the prey. Expressed by the venom gland. Belongs to the cathelicidin family.
