Activation of PKA occurs when cAMP binds to the two regulatory subunits of the tetrameric PKA holoenzyme resulting in release of active catalytic subunits.
Three catalytic (C) subunits have been identified, designated Calpha, Cbeta and Cgamma, that each represent specific gene products.
Calpha and Cbeta are closely related (93%aa sequence similarity), whereas Cgamma displays 83% and 79% similarity to Calpha and Cbeta, respectively.
Activation of transcription upon elevation of cAMP levels results from translocation of PKA to the nucleus where it phosphorylates the transcription factor cAMP response element binding protein (CREB) on serine 133 which in turn leads to TFIIB binding to TATA-box-binding protein TBP1, thus linking phospho-CREB to the Pol II transcription initiation complex.
