Description
Biochem/physiol Actions Naturally-occurring activator of cyclic-AMP-dependent protein kinase （PKA）. cAMP is an important second messenger that is linked in many systems to neurotransmitter- or hormone-induced receptor stimulation. The cAMP/PKA signaling pathway has been shown to inhibit cell proliferation, induce differentiation and lead to apoptosis.
