Also known as PKACg

Summary

PRKACG (protein kinase cAMP-activated catalytic subunit gamma, HGNC:9382) is a protein-coding gene on chromosome 9q21.11, encoding cAMP-dependent protein kinase catalytic subunit gamma (P22612). Phosphorylates a large number of substrates in the cytoplasm and the nucleus.

Cyclic AMP-dependent protein kinase (PKA) consists of two catalytic subunits and a regulatory subunit dimer. This gene encodes the gamma form of its catalytic subunit. The gene is intronless and is thought to be a retrotransposon derived from the gene for the alpha form of the PKA catalytic subunit.

Literature-anchored findings (GeneRIF, showing 6)

  • PKA-mediated phosphorylation of GPIbbeta at Ser(166) negatively regulates VWF binding to GPIb-IX and is one of the mechanisms by which PKA mediates platelet inhibition (PMID:12361948)
  • Results suggest that Cgamma and Calpha differ in structure and function in vitro, supporting the hypothesis that functionally different C-subunit isozymes could affect cAMP signal transduction downstream of protein kinase A activation. (PMID:15039079)
  • In human primary pigmented nodular adrenocortical disease tissues, dexamethasone paradoxically stimulates cortisol release through a glucocorticoid receptor-mediated effect on PKA catalytic subunits. (PMID:19383776)
  • Findings show that PKIB and PKA-C kinase can have critical functions of aggressive phenotype of PCs through Akt phosphorylation and that they should be a promising molecular target for PC treatment. (PMID:19483721)
  • Results suggest that PKA can negatively regulate ERalpha, at least in part, through FoxH1. (PMID:19711044)
  • The missense p.74Ile>Met PRKACG mutation is associated with a marked defect in proplatelet formation and a low level in filamin A in megakaryocytes. (PMID:25061177)

All UniProt accessions (1): P22612

UniProt curated annotations — full annotation on UniProt →

Function. Phosphorylates a large number of substrates in the cytoplasm and the nucleus.

Subunit / interactions. 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.

Tissue specificity. Testis specific. But important tissues such as brain and ovary have not been analyzed for the content of transcript.

Disease relevance. Bleeding disorder, platelet-type, 19 (BDPLT19) [MIM:616176] A disorder characterized by increased bleeding tendency due to platelet dysfunction. Clinical features include epistaxis, hematomas, bleeding after tooth extraction, and menorrhagia. The disease is caused by variants affecting the gene represented in this entry.

Activity regulation. Activated by cAMP.

Similarity. Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. cAMP subfamily.
