Alternate Names for DARPP-32 [p Thr75] Antibody

  • DARPP32
  • DARPP-32
  • PPP1R1B
  • protein phosphatase 1, regulatory (inhibitor) subunit 1B
  • regulatory (inhibitor) subunit 1B (dopamine and cAMPregulated phosphoprotein, DARPP-32)


DARPP-32, a dopamine (DA) and cAMP-regulated ~32k phosphoprotein, is associated with dopaminoceptive neurons bearing D-1 receptors in the basal ganglia. The protein inhibits protein phosphatase I when it is phosphorylated on Thr34. In contrast, when DARPP-32 is phosphorylated on Thr75 the protein acts as an inhibitor of PKA. Phosphorylation of DARPP is thought to play a critical role in the regulation of dopaminergic neurotransmission. In addition, the activity of DARPP-32 is also thought to play important roles in the actions of alcohol, caffeine and Prozac
