Scientific background
KCNQ1 (KV7.1) is part of a voltage-gated K+ family that includes 5 other members (KCNQ1-5).
The channel has been intensively studied since it was found that together with MinK (Isk) it is responsible for the cardiac Iks current that controls the duration of the action potential of the human heart. Indeed, mutations in either KV7.1 or MinK can be responsible for long QT syndrome, a cardiac disorder that causes arrhythmias and sudden death1-3.
Although KV7.1 expression and function have been mainly investigated in relation with cardiac function the channel is widely distributed in epithelial tissues where it is involved in physiological functions such as the regulation of acid secretion in the stomach and Cl- secretion into the colon1-3.
