Potent antimicrobial peptide against most of Gram-negative bacteria, some Gram-positive bacteria (Bacillus) and some fungi (C.albicans, P.pastoris, A.terreus, A.nidulans, and C.globosum). 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, stomach, trachea, skin, muscle, heart, kidney, lung, brain, intestine, spleen, liver, and ovary. Belongs to the cathelicidin family. A predicted cleavage site is located at position Val-157-158-Lys, giving a peptide of 34 residues instead of the 30 residues found for the purified protein. The 30 residues cathelicidin-BF could result from a further processing.
