[https://www.uniprot.org/uniprot/TX31A_SCODE TX31A_SCODE] Toxin that acts on KCNE1 and to a lesser extent KCNE3, the auxiliary subunits of potassium channel Kv7.1/KNCQ1 (PubMed:26307551). The toxin reversibly inhibits the slow delayed rectifier potassium currents (IKs) exhibited by the complex KCNQ1-KCNE1 (IC(50)=652 nM) and by the complex KCNQ1-KCNE3 (30% inhibition at 1 uM) (PubMed:26307551). The positively charged part of toxin binds to the negatively charged residues of the N-terminal amphipathic helix from the KCNE1 extracellular region (PubMed:26307551).<ref>PMID:26307551</ref>
