LEIUROPEPTIDE II | Product ID | L8233-100UG |
| Name | LEIUROPEPTIDE II |
| Molecular formula | C125H199N39O47S6 |
| Description |
A 29 amino-acids peptide with 3 disulfide bridges , synthetic, initially isolated from the venom of the Palestine yellow scorpion Leiurus quinquestriatus hebraeus. |
| Biological activity | A specific and potent inhibitor of ClC-2/CLCN2 chloride channel. It slows ClC-2/CLCN2 activation by increasing the latency to first opening by nearly 8-fold but is unable to inhibit open channels, suggesting that this toxin inhibits channel activation gating. GaTx2 does not inhibit ClC-0, ClC-1/CLCN1, ClC-3/CLCN3, ClC-4/CLCN4, CFTR chloride channel, GABRR, calcium-activated chloride channel regulator (Cl(Ca)), Shaker, and Kv1.2/KCNA2. It shows sequence similarities with potassium channel inhibitors, but inhibits chloride channels. It is why the systematic name 'Potassium channel toxin alpha-KTx 8.3' has been moved as alternative name. |
