DARPP-32 (dopamine and cyclic AMP-regulated phosphoprotein, relative molecular mass 32,000) is a cytosolic protein highly enriched in medium-sized spiny neurons of the neostriatum.
It is a bifunctional signaling molecule that controls serine/threonine kinase and serine/threonine phosphatase activity.
Dopamine stimulates phosphorylation of DARPP-32 through D1 receptors and activation of PKA.
PKA phosphorylation of DARPP-32 at Thr34 converts it into an inhibitor of protein phosphatase 1.
DARPP-32 is converted into an inhibitor of PKA when phosphorylated at Thr75 by cyclin-dependent kinase 5 (CDK5).
Mice containing a targeted deletion of the DARPP-32 gene exhibit an altered biochemical, electrophysiological and behavioral phenotype.
