G-protein-coupled receptors (GPCRs) have central roles in intercellular communication. From left to right, Rhodopsin activated by light, T-cell receptor activated by MHC and antigen (green), dopamine receptor activated by dopamine (red), GABA B receptor activated by the agonist baclofen. G alpha proteins (light blue) activate the phosphodiesterase 6 (left), which degrades cGMP, and  adenylyl cyclase (right), which produces cAMP.  cAMP activates the protein kinase C.
