Product Name
DARPP-32 (Thr34) (PPP1R1B), Polyclonal Antibody
Full Product Name
Anti-Phospho-Thr34 DARPP-32
Product Gene Name
Clonality
Polyclonal
Host
Rabbit
Species Reactivity
Rat
Form/Format
100 ul in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug BSA per ml and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.
Purity/Purification
Affinity Purified (Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.)
Specificity
Specific for the ~32k DARPP-32 protein phosphorylated at Thr34. Immunolabeling is blocked by lambda-phosphatase treatment.
Preparation and Storage
For long term storage -20 degree C is recommended. Stable at -20 degree C for at least 1 year.
Molecular Weight
32
Chromosome Location
Chromosome: 10; NC_005109.3 (86100811..86109854). Location: 10q31
3D Structure
ModBase 3D Structure for Q6J4I0
Antigen
Phosphopeptide corresponding to amino acid residues surrounding the phospho-Thr34 of rat DARPP-32.
Immunogen Information
Synthetic phospho-peptide corresponding to amino acid residues surrounding Thr34 conjugated to KLH
Immunogen Species
Rat
Reactivity Assumed Based on 100% Sequence Homology
Bovine, canine, chicken, human, mouse, and non-human primates
Species Reactivity Note
The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will react with bovine, canine, chicken, human, mouse, and non-human primates based on the fact that these species have 100% homology with the amino acid sequence used as antigen.
Biological Significance
DARPP-32 is a dopamine (DA) and cAMP-regulated ~32k phosphoprotein that is associated with dopaminoceptive neurons (Fienberg et al., 1998). The protein inhibits protein phosphatase I when it is phosphorylated on Thr34. In contrast, when DARPP-32 is phosphorylated on Thr75 the protein acts as an inhibitor of PKA (Bibb et al., 1999). Phosphorylation of DARPP-32 is thought to play a critical role in the regulation of dopaminergic neurotransmission. In addition, the activity of DARPP-32 is also thought to play important roles in the actions of alcohol, caffeine and Prozac (Maldve et al., 2002; Lindskog et al., 2002; Svenningsson et al., 2002).

Other Notes

Small volumes of anti-PPP1R1B antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
