  • FunctionRegulatory subunit of the cAMP-dependent protein kinases involved in cAMP signaling in cells. Type II regulatory chains mediate membrane association by binding to anchoring proteins, including the MAP2 kinase.
  • Tissue specificityFour types of regulatory chains are found: I-alpha, I-beta, II-alpha, and II-beta. Their expression varies among tissues and is in some cases constitutive and in others inducible.
  • Sequence similaritiesBelongs to the cAMP-dependent kinase regulatory chain family.
    Contains 2 cyclic nucleotide-binding domains.
  • Post-translational
    Phosphorylated by the activated catalytic chain.
  • Cellular localizationCytoplasm. Cell membrane. Co-localizes with PJA2 in the cytoplasm and at the cell membrane.
