delayed rectifier channels
The potassium-selective ion channels of axons, so called because they change the potassium conductance with a delay after a voltage step. The name is used to denote any axon-like K channel. Various roles eg. regulation of pacemaker potentials, generation of bursts of action potentials or generation of long plateaux on action potentials.
