Blocks small conductance calcium-activated potassium channels (KCNN, SK). Weakly inhibits the Kv7.1/KCNQ1 channel (10 uM of the toxin inhibits currents by 23.3%). Low toxicity by intracerebroventricular injection into mice. Expressed by the venom gland. Has the structural arrangement of an alpha-helix connected to a beta-sheet by disulfide bonds (CSalpha/beta). Belongs to the short scorpion toxin superfamily. Potassium channel inhibitor family. Alpha-KTx 09 subfamily.
