Dual-function peptide with antimicrobial and potassium channel-blocking activities (By similarity). Shows inhibitory activity against Gram-positive bacteria such as M.luteus, S.aureus, B.subtilis, and M.luteus as well as methicillin-resistant S.aureus (MIC=0.1-20 uM) (By similarity) (PubMed:8333834). Does not act on bacteria by disrupting membranes (By similarity). Also moderately inhibits Kv1.1/KCNA1, Kv1.2/KCNA2, and Kv1.3/KCNA3 potassium channels (By similarity). Inhibits potassium channels by interacting with the pore region (By similarity). Does not show hemolytic activity (By similarity). Has the structural arrangement of an alpha-helix connected to a beta-sheet by disulfide bonds (CSalpha/beta). Belongs to the invertebrate defensin family. Type 2 subfamily.
