Target Background

Regulatory subunit of the cAMP-dependent protein kinases involved in cAMP signaling in cells.
Gene References into Functions
  1. This mouse knockout model supports the role of prkar1a as a tumor suppressor gene in the pancreas and points to the PKA pathway as a possible therapeutic target for these lesions. PMID: 27803029
  2. This model, the first describing the germline expression of a PRKAR1A mutation causing dominant repression of cAMP-dependent PKA, reproduced the main features of acrodysostosis 1 in humans. PMID: 27589370
  3. These results therefore provide new information on the complex regulation of cellular death under endoplasmic reticulum stress conditions and bring new insights on the conditions that regulate the pro- versus anti-death functions of PKA. PMID: 27341185
  4. This study demonstrated that loss of one Prkar1a allele was associated with a significant increase in PKA activity in the basolateral (BLA) and central (CeA) amygdala and ventromedial hypothalamus (VMH) in both Prkar1a(+/-) and Prkar1a(+/-)/Prkaca(+/-) mice. PMID: 26992826

  7. PKARIalpha oxidation is an essential step in the angiogenic pathway. PMID: 26258640
  8. PRKAR1A gene and its locus are altered in mixed odontogenic tumors. Expression is decreased in a subset of tumors, and Prkar1a(+) (/) (-) mice do not show abnormalities, which indicates that additional genes play a role in this tumor's pathogenesis. PMID: 25870248
  9. Prkar1a activation enhances beta-catenin transcriptional activity through nuclear localization to PML bodies. PMID: 25299576
  10. Loss of Prkar1a can only promote tumorigenesis when Prkar1a-mediated apoptosis is somehow countered. PMID: 25012505
  11. Data show that mammary-specific loss of Prkar1a leads to elevated type-II PKA isozyme activation and this is sufficient to drive breast carcinogenesis. PMID: 24662820
  12. Results show that mouse Prkar1a and human PRKAR2A exhibited a dynamic spatio-temporal expression in tooth development, whereas neither human PRKAR1A nor mouse Prkar2a showed their expression in odontogenesis. PMID: 24755349
  13. Ablation of Prkar1a interferes with signaling pathways necessary for osteoblast differentiation. PMID: 24506536
  14. This study demonstrated a critical role for cytoplasmic RI-PKA holoenzyme in gene regulation and the overall physiological function of Striatal medium spiny neurons. PMID: 24695708
  15. hypoxia/reoxygenation (H/R)-mediated decrease in PKARIalpha protein levels leads to activation of RSK1, which via phosphorylation of NHE1 induces cardiomyocyte apoptosis. PMID: 24307699
  16. Prkar1a was found to play a critical role in peripheral nerve development. PMID: 24227708
  17. Dysregulated protein kinase A activity in the amygdala-prefrontal cortex circuitry in Prkar1a(+/-) mice is associated with behavioral phenotype of anxiety and a bias for threat PMID: 23531435
  18. PKA activation through mutation in Prkar1a is sufficient to initiate Rac1 signaling, with subsequent reduction of Nf2 and schwannomagenesis. PMID: 23045281
  19. Prkar1a is indeed a tumor suppressor in the thyroid and that loss of this gene leads to hyperthyroidism and follicular thyroid cancer PMID: 22514108
  20. Analysis of protein kinase A activity showed the loss of one Prkar1a allele led to an increase in basal and cAMP-stimulated kinase activity in both the basolateral and central amygdala PMID: 22024111
  21. PRKAR1A enables protein kinase A to phosphorylate BimEL PMID: 21151042
  22. Prkar1a is an osteosarcoma tumor suppressor that defines a molecular subclass in mice. PMID: 20697156

  39. Loss of Prkar1a from the heart causes myocardial development failure, cardiac failure & embryonic demise. These changes may be due to suppression of cardiac-specific transcription by increased protein kinase A activity, leading to myxoma-like changes. PMID: 18316483
