[https://www.uniprot.org/uniprot/TK1C_HADVE TK1C_HADVE] This excitatory toxin inhibits insect calcium-activated potassium (KCa) channels (Slo-type). Pan-neuronal expression in Drosophila is lethal but flies engineered to express the toxin only in clock neurons have defects in circadian rhythm but a normal lifespan.<ref>PMID:10881200</ref> <ref>PMID:17141372</ref> <ref>PMID:18625007</ref> <ref>PMID:18986214</ref>

We have isolated a family of insect-selective neurotoxins from the venom of the Australian funnel-web spider that appear to be good candidates for biopesticide engineering. These peptides, which we have named the Janus-faced atracotoxins (J-ACTXs), each contain 36 or 37 residues, with four disulfide bridges, and they show no homology to any sequences in the protein/DNA databases. The three-dimensional structure of one of these toxins reveals an extremely rare vicinal disulfide bridge that we demonstrate to be critical for insecticidal activity. We propose that J-ACTX comprises an ancestral protein fold that we refer to as the disulfide-directed beta-hairpin.
