Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. These molecules attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins.
Membrane proteins can be integral (I) or peripheral (P), determined by their amino acid structure. Peripheral proteins bind to integral proteins and to cytoskeletal proteins (L). millions of copies per cell. Built into the structure of each of these proteins is molecular information directing the way it sits in its membrane and an address tag targeting it to its home.
