The recombinant peptide moderately increases Kv11.1/KCNH2/ERG1 currents and shifts the voltage-dependence of the channel activation to hyperpolarised potentials (PubMed:31870846). In vivo, induces neurotoxic effects when injected into insects (tested on L.cuprina and A.domesticus) (PubMed:31870846). 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. Monoisotopic mass. Is abundant in venom, since it accounts for 45.2% of precursor counts. The recombinant peptide contains an extra Gly residue at N-terminal position. The recombinant peptide has no effect on Kv1.3/KCNA3, Kv2.1/KCNB1, Kv10.1/KCNH1/EAG1, KCa1.1/KCNMA1, or the drosophila Shaker IR channel. Belongs to the asilidin-12 family.
