GTP-binding proteins or G proteins are transmitting signals outside the cell which cause changes within the cell. They act as molecular switches which are on when binding GTP and off when binding GDP. GTP-binding proteins belong to two families: heterotrimeric G proteins and small GTPases. The images at the left and at the right correspond to one representative G protein, i.e. the crystal structure of human GTP-binding protein complex with nucleotide (2nzj).
