Target Background

Inhibitor of protein-phosphatase 1.
Gene References into Functions
  1. This study strongly suggests that inflammation-regulated DARPP-32 constitutes a key component of H. pylori-mediated gastric tumourigenesis. PMID: 27590997
  2. the results suggest that by inducing dephosphorylation of DARPP-32 at Ser-97 and altering its cytonuclear distribution, glutamate may counteract dopamine/D1 receptor/PKA signaling at multiple cellular levels. PMID: 27998980
  3. Darpp32 interaction with beta-adducin may be the molecular pathway by which environmental changes may rapidly alter responsiveness of striatal neurons involved in the reward system. PMID: 26639316

  5. analysis of cAMP-activated DARPP-32 signalling to the nucleus PMID: 25692798
  6. Results describe the development of new vascular mouse model with a conditional knockout allele of Tsc1 with a Darpp32-Cre allele. This mouse displayed accelerated formation of both kidney cystadenomas and paw hemangiosarcomas. PMID: 25548102
  7. Cannabinoid-stimulated G-protein activity did not differ between DARPP-32 KO and WT mice treated with vehicle or repeated THC. PMID: 26099530
  8. In this work, the dissected postsynaptic topology of the DARPP-32 phosphoprotein provides strong evidence for a compartmentalized and confined distribution in dendritic spines. PMID: 24058659
  9. Adenosine AA receptors in striatal glutamatergic terminals and GABAergic neurons oppositely modulate psychostimulant action and DARPP-32 phosphorylation. PMID: 24312250
  10. This study demonistrated that environment enhanced Darpp32 expression in brain and enhanced totaroad perfermance and short term working menory. PMID: 23558143
  11. DARPP32 has a role in pluripotent stem cell differentiation toward medium-sized spiny neurons PMID: 23250204
  12. l-DOPA-induced activation of ERK and mTORC1 requires DARPP-32 and indicates the importance of the cAMP/DARPP-32 signaling cascade in dyskinesia. PMID: 22753408
  13. DARPP-32 increases interactions between epidermal growth factor receptor and ERBB3 to promote tumor resistance to gefitinib. PMID: 21741919
  14. Data show that the loss of DARPP-32 in striatopallidal neurons produced a robust increase in locomotor activity. PMID: 20682746
  15. results indicate that under chronic dopamine deficiency (a) the A(2A)/cAMP/PKA/DARPP-32 cascade is overactive due to the elevated endogenous phospho-DARPP-32 levels and (b) the A(2A) receptor modulatory effect on ERK1/2 signaling is dysregulated PMID: 19852993
  16. Our data demonstrate that beta(1)- and alpha(2)-adrenoceptors regulate DARPP-32 phosphorylation in neostriatal neurons. PMID: 20236221
  17. Data confirmed that CR specifically increased dopamine- and cAMP-regulated phosphoprotein (Darpp-32), a key regulator of dopamine receptor signaling, in the amygdala. PMID: 19737990
