Any process that modulates the frequency, rate or extent of potassium ion transmembrane transport.

Transfer of an organized electrical impulse across the heart to coordinate the contraction of cardiac muscles. The process begins with generation of an action potential (in the sinoatrial node (SA) in humans) and ends with a change in the rate, frequency, or extent of the contraction of the heart muscles.

Any process that modulates the frequency, rate or extent of potassium ion transmembrane transport.

A process in which a protein is transported to, or maintained in, a specific location in the plasma membrane.

A process in which a protein is transported to, or maintained in, a specific location in the plasma membrane.

A protein complex that forms a transmembrane channel through which potassium ions may cross a cell membrane in response to changes in membrane potential.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
