MSH: A group of enzymes that are dependent on CYCLIC AMP and catalyze the phosphorylation of SERINE or THREONINE residues on proteins. Included under this category are two cyclic-AMP-dependent protein kinase subtypes, each of which is defined by its subunit composition.,CSP: nonEC; enzyme is stimulated by intracellular cyclic AMP, and therefore links that important second messenger system to the equally important protein phosphorylation cascade for transducing biological signals.,NCI: Most cellular effects of cAMP are mediated through PKA by serine or threonine phosphorylation of target proteins. Human Protein Kinase A (cAMP Ser/Thr Protein Kinase Family) is an inactive tetrameric cytoplasmic holoenzyme composed of homo- or heterodimeric regulatory subunits associated with two catalytic subunits. cAMP causes dissociation of inactive holoenzyme into a cAMP-bound dimer of regulatory subunits and two free monomeric catalytic subunits that phosphorylate many cytoplasmic and nuclear substrates. In human, regulator
