Antibacterial peptide active against Gram-positive bacteria, but not on Gram-negative bacteria (By similarity). Has also weak blocking activity on Kv1.1/KCNA1, Kv1.2/KCNA2, Kv1.3/KCNA3, KCa3.1/KCNN4/IK, KCa2.3/KCNN3/SK3 and Kv11.1/KCNH2/ERG1 channels (tested at 1 uM) (By similarity). It inhibits potassium channel current by interacting with the pore region (By similarity). Highly expressed in non-venom gland (hemolymph) and moderately expressed in venom gland. Belongs to the invertebrate defensin family. Type 2 subfamily.
