Potassium voltage-gated channel subfamily KQT member 1 is a potassiumchannelprotein encoded in the human by the KCNQ1gene. Its mutation causes long QT syndrome, K_v7.1 is a voltage and lipid-gated potassium channel present in the cell membranes of cardiac tissue and in inner ear neurons among other tissues. In the cardiac cells, K_v7.1 mediates the I_Ks (or slow delayed rectifying K) current that contributes to the repolarization of the cell, terminating the cardiac action potential and thereby the heart's contraction. It is a member of the KCNQ family of potassium channels.
