subject Description
Ion channels are pore-forming membrane proteins whose functions include establishing a resting membrane potential, shaping action potentials and other electrical signals by gating the flow of ions across the cell membrane, controlling the flow of ions across secretory and epithelial cells, and regulating cell volume. Ion channels are present in the membranes of all cells. Ion channels are considered to be one of the two traditional classes of ionophoric proteins, with the other class known as ion transporters (including the sodium-potassium pump, sodium-calcium exchanger, and sodium-glucose transport proteins, amongst others).

Statistics
Shown below are histograms for all MemProtMD entries in grey and for this collection only in blue. Densities for all entries and for this collection are individually normalised. Publication date, resolution and experimental_method are taken directly from the PDB record, whilst membrane thickness is derived from MemProtMD simulations.
