1. Single nucleotide polymorphisms related to dopamine are associated with individual differences in exploration strategies. Variation in a gene linked to prefrontal dopamine (COMT) predicted the degree of directed exploration, as well as the overall randomness of responding. Variation in a gene linked to striatal dopamine (DARPP-32) predicted the degree of both directed and random exploration.

2. t-Darpp phosphorylation at T39 seems to be crucial for t-Darpp-mediated PKA activation and this activation appears to occur through an association with RI and sequestering of RI away from PKAc. The t-Darpp-RI interaction could be a druggable target to reduce PKA activity in drug-resistant cancer.

10. DARPP-32 is mainly cleaved at Thr(153) by calpain and this cleavage of DARPP-32 reduces CREB phosphorylation via loss of its inhibitory function on PP1; results suggest a novel mechanism of DARPP-32-CREB signalling dysregulation in Alzheimer's disease

19. Bcl-2 and DARPP-32 have roles in regulating inositol 1,4,5-trisphosphate receptor phosphorylation and promoting cell survival

20. High DARPP32/STAT3, DARPP32/STAT5B, and STAT5B/STAT3 ratios were associated with longer patient progression free survival.

1. This study strongly suggests that inflammation-regulated DARPP-32 constitutes a key component of H. pylori-mediated gastric tumourigenesis.

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.

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.
