Cationic amphipathic alpha-helical peptide with antimicrobial activities against E.coli (MIC=6.2 uM), S.aureus (MIC=6.2 uM), and S.cerevisiae (MIC=50 uM). Also shows histamine-releasing activity (30.1% at 10 uM) and a weak hemolytic activity (10.4% at 50 uM). Expressed by the venom gland. Truncated sequences of this peptide have also been found in the venom. It is possible they have been cleaved in the venom. Monoisotopic mass. Belongs to the formicidae venom precursor-01 superfamily.
