ActivationofcAMPdependentproteinkinase,PKA
G-protein coupled receptors (GPCRs) are one of the largest gene families of signaling proteins. Residing in the plasma membrane with seven transmembrane domains, GPCRs respond to extracellular stimuli that include catecholamine neurotransmitters, neuropeptides, larger protein hormones, lipids, nucleotides and other biological molecules. When a GPCR binds its extracellular ligand, it interacts with a G-protein to tran......閱讀全文
