Mechanism of PKA activation
Activation of cAMP-dependent protein kinase
The domain structure of the R-subunit is summarized with cAMP binding sites A and B shown in turquoise and purple, respectively, and the hinge region in yellow. Two disulfide bonds link the R1 protomers at the amino terminus. The C-subunit is indicated in pink.
A-kinase anchoring protein (AKAP)
