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).

The protein kinase A (PKA) alpha/beta/gamma also known as the PKA catalytic subunit plays a significant role in the regulation of cellular functions through phosphorylation. It has alternate names including phospho PKA and PKA C alpha with an approximate molecular weight of 40 kDa. The PKA catalytic subunit is expressed in various tissues throughout the body. This distribution highlights its broad physiological impact given PKA's involvement in numerous cellular processes.
PKA alpha/beta/gamma acts as an important regulatory molecule in signal transduction pathways. It functions by phosphorylating serine and threonine residues on target proteins which alters the activity protein interactions or localization of these substrates. PKA functions as part of the cAMP-dependent PKA holoenzyme complex which includes two regulatory (R) and two catalytic (C) subunits. Activation requires the binding of cAMP to the R subunits causing dissociation and releasing the active C subunits to exert their effects.
PKA alpha/beta/gamma integrates into the cAMP signaling pathway which modulates numerous physiological processes such as metabolism gene expression and cell growth. In the cAMP pathway PKA interacts closely with proteins like adenylyl cyclase and phosphodiesterases which respectively increase and decrease cAMP levels affecting PKA activation state and subsequent cellular responses. PKA also plays roles within the MAPK/ERK pathway where it intersects with other kinases to influence cell cycle progression and differentiation.
PKA alpha/beta/gamma has connections to cancer and cardiovascular diseases. Mutations or dysregulation of PKA activity can lead to abnormal cell proliferation and survival contributing to tumorigenesis. The catalytic subunit is also linked to cardiovascular disorders through its impact on heart rate and contractility. Interaction with proteins such as AKAPs (A-kinase anchoring proteins) can localize PKA activity affecting local signaling cascades that influence disease pathology.
