GaTx2 

Selective blocker of ClC2 (CLCN2) chloride channels

氯離子通道蛋白2（CLCN2、CLC2）選擇性阻斷劑

GaTx2 (gating modifier of anion channels 2) was isolated from the venom of Leiurus quinquestriatus hebraeus.  is the most potent peptide inhibitor of ClC-2 (CLCN2) chloride channel ever described. K_d value is close to 20 pM. slows ClC-2 activation but without altering channel conductance. The effect is voltage-dependent. This inhibitory effect was highlighted on rabbit ClC-2 channels expressed in oocytes. It has no effect on ClC-0, ClC-1, ClC-3, ClC-4, CFTR, GABA_C, Xenopus Cl_Ca, Shaker B or Kv1.2 channels. Structurally,  is composed of two β-strands and one α-helix. This peptide is also called Leiuropeptide II. Bears 89, 93 and 96% identity with OdK1, neurotoxin PO1 and leiuropeptide III, respectively.
