The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure.

Although membrane proteins play an important role in all organisms, their purification has historically, and continues to be, a huge challenge for protein scientists. In 2008, 150 unique structures of membrane proteins were available, [14] and by 2019 only 50 human membrane proteins had had their structures elucidated. [13]
Single-pass membrane proteins cross the membrane only once, while multi-pass membrane proteins weave in and out, crossing the membrane several times. Single pass membrane proteins can be categorized as Type I, which are positioned such that their carboxyl-terminus is towards the cytosol, or Type II, which have their amino-terminus towards the ...
At the top level are all alpha proteins (domains consisting of alpha helices), all beta proteins (domains consisting of beta sheets), and mixed alpha helix/beta sheet proteins. While most proteins adopt a single stable fold, a few proteins can rapidly interconvert between one or more folds. These are referred to as metamorphic proteins. [5]
Lipid-anchored proteins (also known as lipid-linked proteins) are proteins that are covalently attached to lipids embedded into biological membranes. The lipid-anchored protein can be located on either side of the cell membrane. Thus, the lipid serves to anchor the protein to the cell membrane. [1] [2] Such proteins are a type of proteolipids.

Many hydrolases, and especially proteases associate with biological membranes as peripheral membrane proteins or anchored through a single transmembrane helix. [4] Some others are multi-span transmembrane proteins, for example rhomboid protease.
