Known modulators of PKA activity include factors that either activate or inhibit AC (Adenylate Cyclase), resulting in an increase or decrease in cAMP (Cyclic Adenosine 3',5'-monophosphate) levels. The enzyme occurs naturally as a four-membered structure with two regulatory (R) and two catalytic (C) subunits.KA, once activated can phosphorylate several other substrates. The ADR-Alpha/Beta stimulation of cAMP-PKA phosphorylates several proteins related to excitation-contraction coupling like activation of RyR (Ryanodine Receptor), Pln (Phospholamban), CRP (C-Reactive Protein) but inhibits TnnI (Troponin-I).
