Enzyme Function | FUNCTION: Dual-function toxin that completely inhibits the activity of trypsin at a molar ratio of 1:1 (dissociation constant of 107 nM) and that inhibits mKv1.3/KCNA3 potassium channel currents with an IC(50) of 6.2 nM (where 1 uM inhibits 80% of currents). Also has weak inhibitory activity against mKv1.1/KCNA1 (where 1 uM inhibits less than 50% of currents), hKv1.2/KCNA2 (where 1 uM inhibits less than 50% of currents), and hKCa2.3/KCNN3. {ECO:0000269|PubMed:22354971}. |
