The Regulatory Subunit: A Schematic representation of the structural domains encoded by the PKA regulatory subunits. B Two representations of the predicted AlphaFold structure of a PRKAR1B dimer. The DD domain is colored in magenta, the inhibitory segment is colored in grey, CNB-A in blue, and CNB-B in orange. The linker region between the two CNB’s is colored in black
