Among them, the dopamine D2 receptor (D2R) is most extensively studied. WebSHP-1 triggers intracellular pro-apoptotic signals by the induction of p53 and Bax, while SHP- activates the tyrosine kinase Src that induces the phosphorylation of protein tyrosine phosphatase receptor type J (PTPRJ), which, in turn, dephosphorylates phosphatidylinositol 3-kinase (PI3K/Akt) and extracellular signal-regulated protein kinases 1 and 2 (ERK1/2), …

WebDRD2 desensitization is regulated by G protein-coupled receptor kinase 6 (GRK6) and beta-arrestin 2 (ARRB2). Following the activation of DRD2 by dopamine, GRK6 phosphorylates the receptor, and then ARRB2 binds to the phosphorylated receptors and prevents further G-protein activation. After this process, DRD2 is internalized from the …
