Antimicrobial peptide with activities against E.coli (MIC=1.3 uM), S.aureus (MIC=3.1 uM), and S.cerevisiae (MIC=50 uM). Also shows histamine-releasing activity (32.9% at 10 uM). Does not show hemolytic activity, even at 50 uM. It is a short peptide for which no alpha-helical region has been predicted. 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. Belongs to the formicidae venom precursor-01 superfamily.
