PRKACA (cAMP-dependent protein kinase catalytic subunit alpha) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. In the public catalogues the evidence so far is association rather than a proven role. Tied to Hepatocellular carcinoma. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Phosphorylates a large number of substrates in the cytoplasm and the nucleus. Phosphorylates CDC25B, ABL1, NFKB1, CLDN3, histone H1.4 (H1-4), PSMC5/RPT6, PJA2, RYR2, RORA, SLC6A6, SOX9, UHRF1 and VASP. Regulates the abundance of compartmentalised 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. Involved in chondrogenesis by mediating phosphorylation of SOX9. Location: Cytoplasm; Cell membrane; Membrane; Nucleus (UniProt). Locus 19p13.12 (HGNC).
