The function of KCNA10 (potassium voltage-gated channel subfamily A member 10, ENSG00000143105) is as follows. Voltage-gated potassium ion channel that mediates K(+) permeability of excitable membranes. When opened in response to the voltage difference across the membrane, KCNA10 channel selectively allows the flow of potassium ions across the membrane down their electrochemical gradient. .
