Toxin that shows weak activity against voltage-gated potassium channels (Kv), and no activity against serine proteases (PubMed:24418069). The recombinant toxin shows a weak inhibition on Kv1.1/KCNA1 (59.2% inhibition at 10 uM) (PubMed:24418069). Expressed by the venom gland. The recombinant toxin does not show activity on Kv1.2/KCNA2, Kv1.3/KCNA3, Kv2.1/KCNB1 and Kv4.3/KCND3 channels, as well as on calcium (Cav) and sodium channels (Nav). It also does not show detectable activity against trypsin, kallikrein, chymotrypsin, and thrombin. Belongs to the venom Kunitz-type family. 02 (native) subfamily.
