The M-current regulates the subthreshold electrical excitability of many neurons,
determining their firing properties and responsiveness to synaptic input. To date, however,
the genes that encode subunits of this important channel have not been identified. The
biophysical properties, sensitivity to pharmacological blockade, and expression pattern of
the KCNQ2 and KCNQ3 potassium channels were determined. It is concluded that both
these subunits contribute to the native M-current.
