WebWhen a ligand binds to a G protein-coupled receptor, a guanine nucleotide-binding protein, or G protein, activates a second messenger cascade which can alter gene transcription, regulate other proteins in the cell, release intracellular Ca 2+, or directly affect ion channels on the membrane. WebMay 14, 2024 · How G Proteins Work In the inactive state, Gα has GDP in its binding site. When a hormone or other ligand binds to the associated GPCR, an allosteric change takes place in the receptor (that is, its tertiary structure changes). This triggers an allosteric change in Gα causing GDP to leave and be replaced by GTP. on this day in musical history
