Biol. Chem. 266:10189-10195(1991). CC -!- FUNCTION: Phosphorylates a large number of substrates in the cytoplasm CC and the nucleus (By similarity). Phosphorylates CDC25B, ABL1, NFKB1, CC CLDN3, PSMC5/RPT6, PJA2, RYR2, RORA, SOX9 and VASP (By similarity). CC Regulates the abundance of compartmentalized pools of its regulatory CC subunits through phosphorylation of PJA2 which binds and ubiquitinates CC these subunits, leading to their subsequent proteolysis. RORA is CC activated by phosphorylation. Required for glucose-mediated adipogenic CC differentiation increase and osteogenic differentiation inhibition from CC osteoblasts (By similarity). Involved in chondrogenesis by mediating CC phosphorylation of SOX9 (By similarity). Involved in the regulation of CC platelets in response to thrombin and collagen; maintains circulating CC platelets in a resting state by phosphorylating proteins in numerous CC platelet inhibitory pathways when in complex with NF-kappa-B (NFKB1 and CC NFKB2) and I-kappa-B-alpha (NFKBIA), but thrombin and collagen disrupt CC these complexes and free active PRKACA stimulates platelets and leads CC to platelet aggregation by phosphorylating VASP. RYR2 channel activity CC is potentiated by phosphorylation in presence of luminal Ca(2+), CC leading to reduced amplitude and increased frequency of store overload- CC induced Ca(2+) release (SOICR) characterized by an increased rate of CC Ca(2+) release and propagation velocity of spontaneous Ca(2+) waves, CC despite reduced wave amplitude and resting cytosolic Ca(2+). PSMC5/RPT6 CC activation by phosphorylation stimulates proteasome. Negatively CC regulates tight junctions (TJs) in ovarian cancer cells via CLDN3 CC phosphorylation. NFKB1 phosphorylation promotes NF-kappa-B p50-p50 DNA CC binding. Involved in embryonic development by down-regulating the CC Hedgehog (Hh) signaling pathway that determines embryo pattern CC formation and morphogenesis (By similarity). Prevents meiosis CC resumption in prophase-arrested oocytes via CDC25B inactivation by CC phosphorylation (By similarity). May also regulate rapid eye movement CC (REM) sleep in the pedunculopontine tegmental (PPT) (By similarity). CC Phosphorylates APOBEC3G and AICDA. Phosphorylates HSF1; this CC phosphorylation promotes HSF1 nuclear localization and transcriptional CC activity upon heat shock (By similarity).

CC -!- CATALYTIC ACTIVITY: CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl- CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA- CC COMP:11604, ChEBI:CHEBI:15378, ChEBI:CHEBI:29999, ChEBI:CHEBI:30616, CC ChEBI:CHEBI:83421, ChEBI:CHEBI:456216; EC=2.7.11.11; CC -!- CATALYTIC ACTIVITY: CC Reaction=ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L- CC threonyl-[protein]; Xref=Rhea:RHEA:46608, Rhea:RHEA-COMP:11060, CC Rhea:RHEA-COMP:11605, ChEBI:CHEBI:15378, ChEBI:CHEBI:30013, CC ChEBI:CHEBI:30616, ChEBI:CHEBI:61977, ChEBI:CHEBI:456216; CC EC=2.7.11.11; CC -!- ACTIVITY REGULATION: Allosterically activated by various compounds, CC including ATP. Activated by cAMP; the nucleotide acts as a dynamic and CC allosteric activator by coupling the two lobes of apo PKA, enhancing CC the enzyme dynamics synchronously and priming it for catalysis. CC -!- SUBUNIT: A number of inactive tetrameric holoenzymes are produced by CC the combination of homo- or heterodimers of the different regulatory CC subunits associated with two catalytic subunits. cAMP causes the CC dissociation of the inactive holoenzyme into a dimer of regulatory CC subunits bound to four cAMP and two free monomeric catalytic subunits. CC Activates cAMP-sensitive PKAI and PKAII holoenzymes by interacting with CC regulatory subunit (R) of PKA, PRKAR1A/PKR1 and PRKAR2A/PKR2, CC respectively. Interacts with NFKB1, NFKB2 and NFKBIA in platelets; CC these interactions are disrupted by thrombin and collagen. Binds to CC ABL1 in spermatozoa and with CDC25B in oocytes (By similarity). CC Interacts with APOBEC3G and AICDA (By similarity). Interacts with CC RAB13; downstream effector of RAB13 involved in tight junction assembly CC (By similarity). Found in a complex at least composed of MROH2B, PRKACA CC and TCP11 (By similarity). Interacts with MROH2B (By similarity). CC Interacts with TCP11 (By similarity). Interacts with HSF1 (By CC similarity). {ECO:0000250, ECO:0000250|UniProtKB:P05132, CC ECO:0000250|UniProtKB:P17612}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
