Immunogen Synthesized phosphopeptide derived from human DARPP-32 around the phosphorylation site of threonine 75 (A-Y-TP-P-P).
Specificity DARPP-32 (Phospho-Thr75) Antibody detects endogenous levels of DARPP-32 only when phosphorylated at threonine 75.
Purification Affinity chromatography
Alternative Name DARPP32
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.
