... Ga in the off state has GDP bound and does not activate downstream signaling molecules. When a GPCR is activated by ligand, it stimulates Ga subunits to bind GTP instead of GDP and become active, dissociating from the receptor and from the b/g subunits to activate downstream signaling factors like t ...

... Receptors are protein switches that control biochemical processes in a cell. The switches are turned on through the binding of molecules called ligands. Much as a substrate binds an enzyme to trigger a reaction, a ligand reversibly attaches to a binding site on a receptor protein to activate a cellu ...

VLDL receptor
The very-low-density-lipoprotein receptor (VLDLR) is a transmembrane lipoprotein receptor of the low-density-lipoprotein (LDL) receptor family. VLDLR shows considerable homology with the members of this lineage. Discovered in 1992 by T. Yamamoto, VLDLR is widely distributed throughout the tissues of the body, including the heart, skeletal muscle, adipose tissue, and the brain, but is absent from the liver. This receptor has an important role in cholesterol uptake, metabolism of apoprotein-E-containing triacylglycerol-rich lipoproteins, and neuronal migration in the developing brain. In humans, VLDLR is encoded by the VLDLR gene. Mutations of this gene may lead to a variety of symptoms and diseases, which include type I lissencephaly, cerebellar hypoplasia, and atherosclerosis.
