WebIn cell biology, protein kinase A ( PKA) is a family of enzymes whose activity is dependent on cellular levels of cyclic AMP (cAMP). PKA is also known as cAMP-dependent protein … Web1 Introduction. Cyclic adenosine monophosphate (cAMP) is a common second messenger that is regulated by the activation of G protein-coupled receptors (GPCRs) and mediates numerous biological responses. Quantification of intracellular cAMP levels remains an important methodology in molecular pharmacological studies of GPCRs.
