Expressed by the venom gland. Has the structural arrangement of an alpha-helix connected to antiparallel beta-sheets by disulfide bonds (CS-alpha/beta). Has no effect on voltage-gated potassium channels Kv1.1/KCNA1, Kv1.2/KCNA2, Kv1.3/KCNA3 and Shaker IR (with inactivation domain removed) and on intermediate conductance calcium-activated potassium channel KCa3.1/KCNN4. Does not show antimicrobial activity as well. Belongs to the short scorpion toxin superfamily. Potassium channel inhibitor family. Alpha-KTx 10 subfamily.
