In signalling pathways, G-proteins act as transducers and convert signals from one form to another form, by binding to other proteins in the plasma membrane of a cell. They can bind GTP or GDP. G-proteins can be either trimeric or monomeric. Monomeric G-proteins transduce signals from enzyme-linked receptors whereas trimeric G-proteins transduce signals from G-protein linked receptors [1].
