abstract：:Hormones and cytokines regulate many cellular functions by activating the ubiquitous cAMP-dependent protein kinase (A kinase) system. Newly synthesized cAMP molecules bind to regulatory (R) subunits in A kinase holoenzymes, causing them to release their catalytic (C) subunits. These free C subunits then phosphorylate ...
