Abstract

Brain fast transient K??? channel (A channel) is known to be modulated by PKC activation. We studied, by two-electrode voltage clamp, the molecular mechanism of modulation by PKC activation of A-channels expressed in Xenopus oocytes from the Shaker H4 clone. The modulation is inhibitory affecting primarily the maximal conductance of the channels. A secondary effects is a small change in the voltage-dependence of activation and inactivation of the channel.
