Transmembrane
A transmembrane protein is a protein which is associated with the lipid bilayer in the membrane. The protein runs right through the membrane with both cytosolic and extracellular domains. Transmembrane proteins are amphipathic; the hydrophobic regions interact with lipid tails inside the lipid bilayer and the hydrophillic regions are exposed [1].
