Introduction:The Regulatory (R) subunit of Protein Kinase A (PKA) inhibits its kinase activity by shieldingthe Catalytic (C) subunit from physiological substrates. This inhibition is reversed in response to extra–cellular signals that increase cAMP levels in the cytoplasm. Upon cAMP bindingto R, C is allosterically released from R, activatinga spectrum of downstream signalingcascades. Crystallographic data indicated that a series of distinct conformational changes within CBD–A must occur to relay the cAMP signal from the cAMP bindingsite to the R:C interaction interface. One critical cAMP relay site within the CBD–A of R has been identified as Asp170 because the D170A mutation selectively reduces the negative cooperativity between the cAMP– and C–recognition sites (i.e. the KD for the R:C complex in the presence of cAMP is reduced by more than 12–fold), without significantly compromisingthe high affinity of R for both bindingpartners.
