Vetter M, Zenn H, Mendez E, van den Boom H, Herberg F, Skålhegg B. The testis-specific C?2 subunit of PKA is kinetically indistinguishable from the common C?1 subunit of PKA. BMC Biochem. 2011;12:40 pubmed publisher
..This is also the case for their potency to inhibit catalytic activities of C?2 and C?1. We conclude that the regulatory complexes formed with either C?1 or C?2, respectively, are indistinguishable. ..
