Abstract

Fifty years ago, cyclic AMP was discovered as a second messenger of hormone action, heralding the age of signal transduction. Many cellular processes were found to be regulated by cAMP and the related cyclic GMP. Cyclic nucleotides function by binding to and activating their effectors - protein kinase A, protein kinase G, cyclic-nucleotide-regulated ion channels and the guanine nucleotide-exchange factor Epac. Recent structural insights have now made it possible to propose a general structural mechanism for how cyclic nucleotides regulate these proteins.
