GaTx1 

Selective blocker of CFTR channels(CFTR通道選擇性阻斷劑)

The GaTx1 peptide was originally isolated from the venom of Leiurus quinquestriatus hebraeus.  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.  is a valuable tool to explore the function of CFTR.
