KCNQ-Encoded Potassium Channels as Therapeutic Targets
Abstract
Kv7 channels are voltage-gated potassium channels encoded by KCNQ genes that have a considerable physiological impact in many cell types. This reliance upon Kv7 channels for normal cellular function, as well as the existence of hereditary disorders caused by mutations to KCNQ genes, means that pharmacological targeting of these channels has broad appeal. Consequently, a plethora of chemical entities that modulate Kv7 channel activity have been developed. Moreover, Kv7 channels are influenced by many disparate intracellular mediators and trafficking processes, making upstream targeting an appealing prospect for therapeutic development. This review covers the main characteristics of these multifunctional and versatile channels with the aim of providing insight into the therapeutic value of targeting these channels.
Keywords: KCNQ genes; Kv7 channel; arrhythmia; epilepsy; retigabine; smooth muscle contraction.
