Anti-phospho-DARPP32 (pThr75) antibody produced in rabbit, affinity isolated antibody, buffered aqueous glycerol solution, sufficient for 10 blots

Not available outside of the UK & Ireland.

Application

Anti-phospho-DARPP32 (pThr75) antibody produced in rabbit is suitable for dot blot and western blot analysis at a working dilution of 1:1000 using rat caudate lysates.

Biochem/physiol Actions

Dopamine D1 receptor stimulation enhances cAMP formation, resulting in the phosphorylation of DARPP32. Phosphorylation of DARPP32 plays an important role in the regulation of dopaminergic neurotransmission. The activity of this protein has an important role in the actions of alcohol, caffeine and Prozac^®.

General description

DARPP32 is a phosphoprotein with a molecular mass of 32kDa. It is regulated by dopamine (DA) and cAMP and is associated with dopaminoceptive neurons bearing D-1 receptors in the basal ganglia. DARPP32 is a target for the actions of dopamine.

Immunogen

synthetic phosphopeptide corresponding to amino acids residues surrounding the DARPP32 phosphorylated on threonine 75.

Other Notes

The labeling by the antibody to DARPP32 Thr⁷⁵ is markedly increased by okadaic acid treatment.

Physical form

Solution at 100 µL in 10 mM HEPES, pH 7.5, 150 mM NaCl, 100 µg/mL BSA, and 50% glycerol.

Target description

DARPP32 phosphorylated on Thr⁷⁵ acts as an inhibitor of PKA.
