Poorly competes with (125)I-kaliotoxin binding on rat brain synaptosome (IC(50)>100 nM). Is a poor Kv1.3 ligand (PubMed:23523531). May have as real target KCa1.1/KCNMA1 channel (By similarity). Shows weak toxicity on mice (PubMed:23523531). Expressed by the venom gland. Has the structural arrangement of an alpha-helix connected to a beta-sheet by disulfide bonds (CSalpha/beta). LD(50) is >25 ug/kg by intracerebroventricular injection into mice. Belongs to the short scorpion toxin superfamily. Potassium channel inhibitor family. Alpha-KTx 16 subfamily.
