Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Purification The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name DARPP-32 (PPP1R1B Antibody Abstract)
Background Dopaminergic signaling in midbrain neurons is essential to multiple brain functions and involves the activation of dopamine receptors,nsuch 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.
