Overview

Potassium voltage-gated channel subfamily A member 10 (KCNA10) is a protein encoded by the KCNA10 gene and forms a voltage-gated potassium ion channel, specifically the Kv1.8 subunit. It plays key roles in excitable membranes by selectively mediating potassium ion flow in response to changes in membrane voltage. KCNA10 is involved in regulating a variety of physiological processes, including neuronal excitability, neurotransmitter release, heart rate, insulin secretion, and epithelial electrolyte transport. It is especially critical to the function of vestibular hair cells in the inner ear, where it shapes distinctive outwardly rectifying potassium conductances necessary for normal sensory processing of motion and balance. Its dysfunction has been linked to developmental and epileptic encephalopathies and episodic ataxia. KCNA10 belongs to the shaker-related subfamily of potassium channels and is uniquely regulated by cyclic GMP
