In the inactive conformation, the a-subunit of the G protein binds to GDP and is bound to a beta-gamma complex (a). Upon receptor activation by its ligand, there is an exchange of GDP for GTP (b).

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 acid ...

GPCRs are integral membrane proteins that span the entire lipid bilayer and are involved in many critical processes, such as responding to adrenaline or other signals. These proteins are also the ...
