Background: DARPP32 is expressed in medium-sized spiny neurons that also express dopamine D1 receptors. The function of DARPP32 seems to be regulated by receptor stimulation. Both dopaminergic and glutamatergic (NMDA) receptor stimulation regulate the extent of DARPP32 phosphorylation, but in opposite directions. Dopamine D1 receptor stimulation enhances cAMP formation, resulting in the phosphorylation of DARPP32 and phosphorylated DARPP32 is a potent protein phosphatase 1. NMDA receptor stimulation elevates intracellular calcium, which leads to activation of calcineurin and dephosphorylation of phospho DARPP32, thereby reducing the phosphatase 1 inhibitory activity of DARPP32.Synonyms: DARPP-32, Dopamine- and cAMP-regulated neuronal phosphoprotein, FLJ20940, PPP1R1B, Protein phosphatase 1 regulatory subunit 1B
