GaTx1: Toxin Properties
The GaTx1 peptide was originally isolated from the venom of Leiurus quinquestriatus hebraeus. This peptide is a potent and selective inhibitor of CFTR, an anion selective channel belonging to the ABC transporter superfamily. It was shown to block CFTR channels in a state dependent manner by acting from the internal face of the channel and it is supposed to be a non competitive inhibitor of ATP-dependent channel gating. GaTx1 is a valuable tool to explore the function of CFTR.
