Integral membrane protein
ID: integral-membrane-protein
An integral membrane protein is firmly incorporated into a membrane, commonly through contact with the hydrophobic interior of the lipid bilayer. Extraction behavior is an operational distinction: it resists treatments that remove many peripheral membrane proteins. Transmembrane proteins are one class; integral does not mean spanning.[ref]
