Protein kinase A (PKA, cAMP-dependent protein kinase) is a key element of a ubiquitous signaling pathway important in the cell cycle, cellular communication, memory formation and behavior. PKA is composed of two catalytic (PKAc; Protein Kinase A catalytic subunit) and two regulatory subunits (PKAr). Upon binding cAMP, the complex dissociates to PKAr dimer and two activated PKAc ser/thr protein kinase catalytic monomers. The released PKAc can translocate into the nucleus and exert a regulatory role in the activation of multiple nuclear hormone receptors. However, PKAc-mediated activation of tonicity-dependent gene expression is cAMP independent. Humans express three types of PKAc subunit – PKAc alpha is present in most human tissues, PKAc beta and gamma are tissue-specific, the later is found in testes.


The antibody 6D2.1 strongly reacts with human proteinkinase A catalytic (PKAc) alpha subunit, and weakly with PKAc gamma subunit (both around 40 kDa). The recognized epitope of PKAc alpha is identical between man, sheep, pig, ox and dog.

Regulatory Status


Peptide corresponding to amino acids ESPAQNTAHLDQFERIK of human proteinkinase A c alpha (PKAc alpha).

Species Reactivity:

  • Human
  • Other not determined

Negative Species:


  • Western Blotting
    Recommended dilution: 0.5-1 μg/ml
    Positive control: HeLa human cervix carcinoma cell line
    Application note: To detect PKAc gamma, use a more concentrated lysate from a tissue expressing this subunit (testis).
Usage note:
Indicated dilutions are recommended starting points for use of this product. Working concentrations should be determined by the investigator.
