Overlay histogram showing HeLa cells stained with ab76238 (unpurified) (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab76238, 1/100 dilution) for 30 min at 22oC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22oC.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The cAMP Protein Kinase Catalytic subunit also known as protein kinase A (PKA) catalytic subunit plays an important role as an enzyme that phosphorylates various target proteins. This is an important component of the protein kinase A signaling pathway. The subunit has an approximate mass of 40 kDa and is widely expressed in multiple tissues across the body allowing it to affect numerous physiological functions. As a catalytic subunit of cAMP-dependent protein kinase it forms part of the larger enzyme complex that is activated by the binding of cAMP.
Biological function summary

The catalytic subunit of protein kinase A modulates cellular processes by transferring a phosphate group from ATP to specific serine/threonine residues on substrates. It is part of a holoenzyme complex composed of two regulatory and two catalytic subunits; when cAMP binds to the regulatory subunits it releases the catalytic subunits allowing them to execute their activity. This release and activation result in the regulation of glycogen sugar and lipid metabolism among others.

Pathways

The cAMP Protein Kinase integrates deeply into the cAMP signaling and MAPK/ERK pathways. These pathways regulate various processes like cell growth differentiation and apoptosis. The catalytic subunit acts downstream of cAMP generation by adenylyl cyclase interacting with other proteins such as CREB (cAMP response element-binding protein) which directly affects transcription and gene expression.

The cAMP Protein Kinase catalytic subunit has been linked to conditions including Carney complex and Cushing’s syndrome. Mutations affecting this subunit can lead to dysregulated cAMP signaling impacting proteins like regulatory subunit PRKAR1A that are important in controlling PKA activity. Conditions such as these often arise from aberrations in cAMP signaling pathways reflecting the extensive influence of the cAMP Protein Kinase on homeostasis and disease.

Regulates the abundance of compartmentalized pools of its regulatory subunits through phosphorylation of PJA2 which binds and ubiquitinates these subunits, leading to their subsequent proteolysis (PubMed : 21423175). RORA is activated by phosphorylation (PubMed : 21514275). Required for glucose-mediated adipogenic differentiation increase and osteogenic differentiation inhibition from osteoblasts (PubMed : 19949837). Involved in chondrogenesis by mediating phosphorylation of SOX9 (By similarity). Involved in the regulation of platelets in response to thrombin and collagen; maintains circulating platelets in a resting state by phosphorylating proteins in numerous platelet inhibitory pathways when in complex with NF-kappa-B (NFKB1 and NFKB2) and I-kappa-B-alpha (NFKBIA), but thrombin and collagen disrupt these complexes and free active PRKACA stimulates platelets and leads to platelet aggregation by phosphorylating VASP (PubMed : 15642694, PubMed : 20356841). Prevents the antiproliferative and anti-invasive effects of alpha-difluoromethylornithine in breast cancer cells when activated (PubMed : 17333334). RYR2 channel activity is potentiated by phosphorylation in presence of luminal Ca(2+), leading to reduced amplitude and increased frequency of store overload-induced Ca(2+) release (SOICR) characterized by an increased rate of Ca(2+) release and propagation velocity of spontaneous Ca(2+) waves, despite reduced wave amplitude and resting cytosolic Ca(2+) (PubMed : 17693412).

NFKB1 phosphorylation promotes NF-kappa-B p50-p50 DNA binding (PubMed : 15642694). Required for phosphorylation of GLI transcription factors which inhibits them and prevents transcriptional activation of Hedgehog signaling pathway target genes (By similarity). GLI transcription factor phosphorylation is inhibited by interaction of PRKACA with SMO which sequesters PRKACA at the cell membrane (By similarity). Involved in embryonic development by down-regulating the Hedgehog (Hh) signaling pathway that determines embryo pattern formation and morphogenesis most probably through the regulation of OFD1 in ciliogenesis (PubMed : 33934390).
