Application Abreviews Notes
WB 1/10000 - 1/50000. Detects a band of approximately 52 kDa (predicted molecular weight: 45 kDa).
IHC-P 1/100 - 1/250.
ICC/IF 1/100 - 1/250.
IP 1/50.
  • Application notes
    Is unsuitable for Flow Cyt.
  • Target

    • Function
      Regulatory 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 specificity
      Four 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 similarities
      Belongs to the cAMP-dependent kinase regulatory chain family.
      Contains 2 cyclic nucleotide-binding domains.
    • Post-translational
      Phosphorylated by the activated catalytic chain.
    • Cellular localization
      Cytoplasm. Cell membrane. Colocalizes with PJA2 in the cytoplasm and the cell membrane.
