A G-protein coupled receptor is a membrane receptor that interacts with a special protein called a G-protein.

Extra Note: There are two classes of G proteins. The first function as monomeric small GTPases (small G-proteins), while the second function as heterotrimeric G protein complexes. The latter class of complexes is made up of alpha (α), beta (β) and gamma (γ) subunits.^[1] In addition, the beta and gamma subunits can form a stable dimeric complex referred to as the beta-gamma complex .
