Recombinant Human Protein Kinase A regulatory subunit-1 alpha is supplied as a recombinant protein for in vitro research use.
Background
The Regulatory
(R) subunit of Protein Kinase A (PKA) inhibits its kinase activity by shielding the 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 binding to R, C is allosterically released from R, activating a spectrum of downstream signaling cascades. Crystallographic data indicated that a series of distinct conformational changes within CBD-A must occur to relay the cAMP signal from the cAMP binding site 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 compromising the high affinity of R for both binding partners.
Product format
Provided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development. Refer to the specifications table for expression format and molecular properties.
Activity & assay information
- Inhibitory Activity: The cAMP-dependent protein kinase, regulatory subunit RIa reversibly inhibits the catalytic subunit Ca of the cAMP-dependent protein kinase PKA. The inhibition of the catalytic subunit can be reversed by the addition of the second messenger cAMP.
