    • Rabbit anti Rat DARPP-32 (pThr75) antibody recognises rat DARPP-32, when phosphorylated at threonine 75. DARPP-32 is a 205 amino acid ~32 kDa member of the protein phosphatase inhibitor 1 family. Originally discovered as a substrate for cAMP-dependent protein kinase which modulates cell signalling in neurons. DARPP-32 is converted into an inhibitor of protein phosphatase-1 when phosphorylated by protein kinase A at threonine 34, as a result of dopaminergic receptor stimulation (Bibb et al. 1999). However this phosphorylation is reversed on stimulation of N-methyl-D-aspartate (NMDA) receptors by glutamate (Halpain et al. 1990). Conversely when phosphorylated at threonine-75 by CDK5, DARPP-32 becomes an inhibitor of protein kinase A (Bibb et al. 1999).

      DARPP-32 is principally expressed in striatal medium spiny neurons and plays a critical role in the regulation of dopaminergic neurotransmission.

    • Application NameYesNoMin DilutionMax Dilution
      Western Blotting(1)1/1000
      For the detection of phosphoproteins, threonine phosphatase inhibitors such as 10mM Sodium Fluoride should be added to the sample buffer. Milk or other casein-based blocking solutions are not recommended as casein is a phosphoprotein and its use can result in high background.

    • Where this antibody has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the antibody for use in their own system using appropriate negative/positive controls.
