Anti-PKAc Purified

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; proteinkinase 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.

Storage Conditions

Store at 2-8°C. Do not freeze.

Specificity

The mouse monoclonal antibody 6D2.1 strongly reacts with human proteinkinase A (an intracellular antigen) 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.

Applications Notes

Western blotting: Recommended dilution: 1 μg/ml; positive control: HeLa human cervix carcinoma cell line. To detect PKAc gamma, use a more concentrated lysate from a tissue expressing this subunit (testis) .
