Amphipathic peptide with antibacterial activities (By similarity). Shows antiviral activities against the herpes simplex virus type-1. It potently inhibits the initial infection by provoking the rupture of viral envelop and the dissociation of proteins from the virions (EC(50) is 0.43 uM). It also effectively inhibits viral attachment (EC(50) is 2.87 uM), viral entry (EC(50) is 4.29 uM) and viral proliferation after infection (EC(50) is 7.86). Morever, it enters mammalian tested cells (Vero) and reduces the intracellular infectivity. Forms an alpha-helical membrane channel in the prey. Expressed by the venom gland. Belongs to the non-disulfide-bridged peptide (NDBP) superfamily. Short antimicrobial peptide (group 4) family.
