<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Phosphorylates a large number of substrates in the cytoplasm and the nucleus (By similarity).

Phosphorylates CDC25B, ABL1, NFKB1, CLDN3, PSMC5/RPT6, PJA2, RYR2, RORA, SOX9 and VASP (By similarity).

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. RORA is activated by phosphorylation. Required for glucose-mediated adipogenic differentiation increase and osteogenic differentiation inhibition from osteoblasts (By similarity).

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. RYR2 channel activity is potentiated by phosphorylation in presence of luminal Ca2+, leading to reduced amplitude and increased frequency of store overload-induced Ca2+ release (SOICR) characterized by an increased rate of Ca2+ release and propagation velocity of spontaneous Ca2+ waves, despite reduced wave amplitude and resting cytosolic Ca2+. PSMC5/RPT6 activation by phosphorylation stimulates proteasome. Negatively regulates tight junctions (TJs) in ovarian cancer cells via CLDN3 phosphorylation. NFKB1 phosphorylation promotes NF-kappa-B p50-p50 DNA binding. Involved in embryonic development by down-regulating the Hedgehog (Hh) signaling pathway that determines embryo pattern formation and morphogenesis (By similarity).

Prevents meiosis resumption in prophase-arrested oocytes via CDC25B inactivation by phosphorylation (By similarity).

May also regulate rapid eye movement (REM) sleep in the pedunculopontine tegmental (PPT) (PubMed:20844122).

Phosphorylates APOBEC3G and AICDA. Phosphorylates HSF1; this phosphorylation promotes HSF1 nuclear localization and transcriptional activity upon heat shock (By similarity).

Asn-3 is deaminated to Asp in more than 25% of the proteins, giving rise to 2 major isoelectric variants, called CB and CA respectively (0.4 pH unit change). Deamidation proceeds via the so-called beta-aspartyl shift mechanism and yields either 'D-Asp-2' (major) or 'D-isoAsp-2' (minor), in addition to L-isomers. Deamidation occurs after the addition of myristate. The Asn-3 form reaches a significantly larger nuclear/cytoplasmic ratio than the 'Asp-2' form.1 Publication
Autophosphorylated. Phosphorylation is enhanced by vitamin K2. Phosphorylated on threonine and serine residues. Phosphorylation on Thr-198 is required for full activity (By similarity).By similarity
Phosphorylated at Tyr-331 by activated receptor tyrosine kinases EGFR and PDGFR; this increases catalytic efficiency.By similarity

A number of inactive tetrameric holoenzymes are produced by the combination of homo- or heterodimers of the different regulatory subunits associated with two catalytic subunits. cAMP causes the dissociation of the inactive holoenzyme into a dimer of regulatory subunits bound to four cAMP and two free monomeric catalytic subunits. The cAMP-dependent protein kinase catalytic subunit binds PJA2. Both isoforms 1 and 2 forms activate cAMP-sensitive PKAI and PKAII holoenzymes by interacting with regulatory subunit (R) of PKA, PRKAR1A/PKR1 and PRKAR2A/PKR2, respectively.

Interacts with NFKB1, NFKB2 and NFKBIA in platelets; these interactions are disrupted by thrombin and collagen. Binds to ABL1 in spermatozoa and with CDC25B in oocytes (By similarity).

Interacts with APOBEC3G and AICDA (By similarity).

Interacts with RAB13; downstream effector of RAB13 involved in tight junction assembly.

Found in a complex at least composed of MROH2B, PRKACA isoform 2 and TCP11 (By similarity).

Interacts with MROH2B (By similarity).

Interacts with HSF1 (By similarity).

Isoform 2 interacts with TCP11 (By similarity).
