Antimicrobial peptide that acts by breaking the cell wall. Is active against Gram-positive bacteria, fungi and antibiotic-resistant pathogens: S.aureus (MIC=5 ug/ml), M.luteus (MIC=5 ug/ml), B.thuringiensis (MIC=10 ug/ml), B.subtilis (MIC=10 ug/ml), C.albicans (MIC=20 ug/ml), methicillin-resistant S.aureus (MIC=5-10 ug/ml), and penicillin-resistant S.epidermidis (MIC=10 ug/ml). Is efficient in curing staphylococcal skin infection in mice, when externally applied. Forms a helical membrane channel in the prey. Expressed by the venom gland. Has no activity against Gram-negative bacteria (E.coli and P.aeruginosa) (PubMed:21876042). Inhibits hepatitis B virus replication in the HepG2.2.15 cell line by about 30% (PubMed:22791717). Belongs to the non-disulfide-bridged peptide (NDBP) superfamily. Short antimicrobial peptide (group 4) family.
