Description

Description

Dopaminergic signaling in midbrain neurons is essential to multiple brain functions and involves the activation of dopamine receptors, such as D1 and D2, which regulate the phosphorylation state of DARPP-32 (dopamine and cyclic AMP-regulated phospho-protein of Mr = 32,000). D1 receptor ligation causes activation of PKA and phosphorylation of DARPP-32 at Thr-34, which converts DARPP-32 to a potent inhibitor of protein phosphatase 1 (PP1). In addition, DARPP-32 is converted to an inhibitor of PKA via phosphorylation at Thr-75 by
cyclin-dependent kinase 5 (Cdk5). D2 receptor ligation inhibits PKA and activates protein phosphatase 2B/calcineurin causing dephosphorylation of DARPP-32. The major function of DARPP-32 may be to inhibit the activity of PP1, which controls the phosphorylation state of neurotransmitter receptors, ion channels, ion pumps, and transcription factors. DARPP-32 -/- mice are defective in the physiologicial and behavioral responses to dopamine. Thus, DARPP-32, a bifunctional signal transduction molecule that differentially controls a Ser/Thr kinase and a Ser/Thr phosphatase, is a critical element of dopaminergic neurotransmission and normal brain function.
