- Background
- CAMP-dependent Protein Kinase (PKA) is composed of two distinct subunits: catalytic (C) and regulatory (R). Four regulatory subunits have been identified: RIalpha, RIbeta, RIIalpha, and RIIbeta. These subunits define type I and II PKAs. Following binding of cAMP, the regulatory subunits dissociate from the catalytic subunits, rendering the enzyme active. Type I and II holoenzymes have three potential C subunits (Calpha, Cbeta, or Cgamma). Type II PKA can be distinguished by autophosphorylation of the R subunits, while type I PKA binds Mg/ATP with high affinity. The cAMP-dependent autophosphorylation of the human RIIalpha subunit occurs at Serine 99 (S99) [Entrez Protein Accession #CAA33094]. Most cells express both type I and type II PKAs. Although the Ralpha isoforms are ubiquitously expressed, the Rbeta isoforms are predominantly found in nervous and adipose tissues. In addition to their enzyme regulatory activity, the RIIalpha and RIIbeta subunits determine the subcellular location of the holoenzymes via their interactions with specific intracellular anchoring proteins. The I65-856.286 antibody recognizes human PKA RIIalpha phosphorylated at S99.
