The human KCNQ3 and KCNQ5 genes encode the pore-forming subunits of Kv7.3 and Kv7.5, respectively. These subunits form heteromeric voltage-gated potassium channels that underlie M-current that regulates repetitive activity in neurons. Mutations in KCNQ3 that reduce M-current are responsible for some forms of benign familial neonatal seizure. Kv7.3/Kv7.5 channels expressed in neurons are therapeutic targets in seizure and cognitive impairment.
