Potassium voltage-gated channel subfamily KQT member 4 also known as voltage-gated potassium channel subunit K_v7.4 is a protein that in humans is encoded by the KCNQ4 gene.^[1]^[2]^[3]

Function

The protein encoded by this gene forms a potassium channel that is thought to play a critical role in the regulation of neuronal excitability, particularly in sensory cells of the cochlea. The encoded protein can form a homomultimeric potassium channel or possibly a heteromultimeric channel in association with the protein encoded by the KCNQ3 gene.^[3]

Clinical significance

The current generated by this channel is inhibited by muscarinic acetylcholine receptor M1 and activated by retigabine, a novel anti-convulsant drug. Defects in this gene are a cause of nonsyndromic sensorineural deafness type 2 (DFNA2), an autosomal dominant form of progressive hearing loss. Two transcript variants encoding different isoforms have been found for this gene.^[3]
