KCNQ3 / TRP channels
Name: Potassium voltage-gated channel subfamily KQT member 3
(KCNQ3)
Official Symbol: KCNQ3
provided by HGNC
Function:
Probably important in the regulation of neuronal excitability. Associates with KCNQ2 or KCNQ5 to form a potassium channel with essentially identical properties to the channel underlying the native M-current, a slowly activating and deactivating potassium conductance which plays a critical role in determining the subthreshold electrical excitability of neurons as well as the responsiveness to synaptic inputs.
