• PubMed Abstract: 
  

  Cyclic AMP binding domains possess common structural features yet are diversely coupled to different signaling modules. Each cAMP binding domain receives and transmits a cAMP signal; however, the signaling networks differ even within the same family of regulatory proteins as evidenced by the long-standing biochemical and physiological differences between type I and type II regulatory subunits of cAMP-dependent protein kinase.
