PRKACG (Protein Kinase cAMP-Activated Catalytic Subunit Gamma) is a crucial member of the cAMP-dependent protein kinase (PKA) family, which plays a central role in intracellular signal transduction pathways regulated by cyclic adenosine monophosphate (cAMP). As a catalytic subunit, PRKACG interacts with regulatory subunits to form the PKA holoenzyme, remaining inactive until cAMP levels rise. Upon cAMP binding, the regulatory subunits dissociate, releasing the catalytic subunit to phosphorylate downstream targets involved in diverse cellular processes, including metabolism, gene expression, ion channel activity, and apoptosis.
Recombinant human PRKACG protein is engineered using biotechnological methods, often expressed in *E. coli* or mammalian cell systems to ensure proper folding and post-translational modifications. This recombinant form retains the kinase activity of native PRKACG, enabling researchers to study its enzymatic mechanisms, substrate specificity, and regulatory interactions in vitro. It serves as a vital tool for investigating PKA-related diseases, such as hormone-resistant cancers, cardiovascular disorders, and metabolic syndromes linked to cAMP signaling dysregulation. Additionally, recombinant PRKACG is utilized in drug discovery to screen inhibitors or activators targeting its kinase domain, offering potential therapeutic avenues. Its structural and functional consistency with endogenous PRKACG, coupled with high purity and reproducibility, makes it indispensable for biochemical assays, structural studies, and cellular pathway analyses.
