Technical Data
DARPP32 (Dopamine and cAMP-regulated Phosphoprotein DARPP32, DARPP 32, DARPP-32, Dopamine- and cAMP-regulated Neuronal Phosphoprotein, FLJ20940, Neuronal Phosphoprotein DARPP-32, Protein Phosphatase 1 Regulatory (Inhibitor) Subunit 1B, PPP1R1B)
Dopamine- and cAMP-Regulated Phosphoprotein, Mr 32kD (DARPP-32), also known as PPP1R1B, is a 23kD protein that anomalously migrates at about 32-35kD on SDS-PAGE. When phosphorylated at T34 by protein kinase A (PKA), DARPP-32 is a potent inhibitor of protein phosphatase 1 (PP1). Dephosphorylation of DARPP-32 at T34 is achieved primarily by the calcium-dependent activation of the phosphatase calcineurin. DARPP-32 is expressed almost exclusively in neuronal tissues, with highest levels in dopamine-innervated neurons.

Suitable for use in Western Blot. Other applications not tested.
