Potassium voltage-gated channel subfamily KQT member 3 (KCNQ3)

Associates with KCNQ2 or KCNQ5 to form a potassium channel with basically identical properties to the channel underlying the native M-current, a slowly activating and deactivating potassium conductance that plays a vital role in setting the subthreshold electrical excitability of neurons as well as the responsiveness to synaptic inputs. Therefore, it's important in the regulation of neuronal excitability.
