Weakly inhibits the Kv1.3/KCNA3 channel (1 uM of the toxin inhibits currents by 13.2%) and Kv7.1/KCNQ1 channel (10 uM of the toxin inhibits currents by 27.7%). Expressed by the venom gland. Has the structural arrangement of an alpha-helix connected to antiparallel beta-sheets by disulfide bonds (CS-alpha/beta). Belongs to the short scorpion toxin superfamily. Potassium channel inhibitor family. Alpha-KTx 29 subfamily.
