Moderately increases Kv11.1/KCNH2/ERG1 currents and shifts the voltage-dependence of the channel activation to hyperpolarised potentials (By similarity). In vivo, induces neurotoxic effects when injected into insects (tested on L.cuprina and A.domesticus) (By similarity). Expressed by the venom gland. Has the structural arrangement of an alpha-helix connected to antiparallel beta-sheets by disulfide bonds (CS-alpha/beta). Monoisotopic mass. Is abundant in venom, since it accounts for 45.2% of precursor counts. Belongs to the asilidin-12 family.
