Antimicrobial peptide (PubMed:27917162, PubMed:29848960). Shows antibacterial activity against all M.massiliense bacterial strains tested (PubMed:29848960). Has antifungal activity against Candida spp. and two Cryptococcus neoformans strains with MICs values ranging from 6.25 to 200 uM (PubMed:27917162). Also shows an inhibitory activity on C.albicans biofilms at high concentrations (PubMed:27917162). Exhibits chemotactic activity for monocytes, neutrophils, and eosinophils (PubMed:29848960). Shows low cytotoxic activity and has weak hemolytic activity on human erythrocytes (PubMed:27917162, PubMed:29848960). In vivo, treatment of infected mice with M.massiliense reduces the bacterial load in the liver, lung, and spleen (PubMed:29848960). Has an amphipathic alpha-helical conformation. Expressed by the venom gland. Belongs to the non-disulfide-bridged peptide (NDBP) superfamily. Medium-length antimicrobial peptide (group 3) family.
