Potassium ion channel cavity structure. Molecular model showing the structure of a cavity formed by potassium ion channel proteins. Ion channels are membrane-spanning proteins that form a pathway for the movement of inorganic ions across cell membranes. Here, in a high potassium concentration, subunits have formed a square antiprism in a cavity near the intracellular entryway. This cavity can hold a potassium ion. This is the KcsA potassium ion (K+) channel from Streptomyces lividans bacteria. The model includes fragment antigen-binding (Fab) antibodies.
