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.
Integral proteins have transmembrane domains that insert directly into the lipid bilayer. These transmembrane domains consist predominantly of nonpolar amino acid residues and may traverse the bilayer once or several times.roteins with one transmembrane domain may have soluble domains at either or both surfaces. Cytochrome b5 has a single hydrophobic segment that forms a hairpin loop, which acts as an anchor to the cytoplasmic surface but is thought not to penetrate the bilayer totally. It is an example of a monotopic protein.
