Membrane proteins are proteins found in cell membranes, either at the surface or on intracellular organelles. Integral membrane proteins such as receptors and ion channels span the membrane. Peripheral membrane proteins, for example some signalling proteins, are tethered by an anchor, via a fatty aci...
Nearly one-third of all proteins in living beings are firmly embedded in abiomembrane—either in a cell's outer membrane or in the boundaries of internal cellular compartments. There, thesemembrane proteinsperform important tasks, serving, for instance, as molecular channels for transporting metabolite...

Cholesterol, an essential component of the eukaryotic plasma membrane, influences the diffusion of lipids (and proteins) but cannot be the only factor responsible for the difference. In addition, lateral diffusion of membrane proteins is cell and compartment-specific. Secondly, transverse diffusion (...
