GTP-binding protein

  • G protein
German: GTP-Bindeprotein
Japanese: グアノシン三リン酸結合タンパク質

Biochemistry. A regulatory protein that acts as a molecular switch. G proteins control a wide range of intracellular processes such as signal transduction between receptors and second messengers, and protein biosynthesis. G protein is activated by binding GTP. It can stimulate or inhibit the activity of an enzyme, and is then again inactivated by hydrolyzing GTP to GDP.
