3 Hence, the selective activation of PKG by cGMP versus cAMP is critical. Cyclic AMP protein kinase cGMP-dependent 1 Homo sapiens
4 Although the C-terminal cyclic nucleotide-binding domain B of PKG binds cGMP with higher affinity than cAMP, the intracellular concentrations of cAMP are typically higher than those of cGMP, suggesting that the cGMP-versus-cAMP selectivity of PKG is not controlled uniquely through affinities. Cyclic AMP protein kinase cGMP-dependent 1 Homo sapiens
5 Although the C-terminal cyclic nucleotide-binding domain B of PKG binds cGMP with higher affinity than cAMP, the intracellular concentrations of cAMP are typically higher than those of cGMP, suggesting that the cGMP-versus-cAMP selectivity of PKG is not controlled uniquely through affinities. Cyclic AMP protein kinase cGMP-dependent 1 Homo sapiens
