应用 | Western Blot(1 µg/mL) |
目标/特异性 | Detects mouse and rat DARPP-32 when phosphorylated at T34 in Western blots. There is weak cross-reactivity with phosphorylated PP1 Inhibitor-1, which contains a nearly identical phosphorylation site. Reactivity with human Phospho-DARPP-32 has not been confirmed. |

R&D Systems personnel manually curate a database that contains references using R&D Systems products. The data collected includes not only links to publications in PubMed, but also provides information about sample types, species, and experimental conditions. Phosphorylation of huntingtin at Ser421 in YAC128 neurons is associated with protection of YAC128 neurons from NMDA-mediated excitotoxicity and is modulated by PP1 and PP2A. | |

背景 | Dopamine- and cAMP-Regulated Neuronal Phosphoprotein, Mr 32 kDa (DARPP-32), also known as PPP1R1B, is a 23 kilodalton protein which anomalously migrates at about 32 - 35 kDa on SDS-PAGE. When phosphorylated at T34 by protein kinase A (PKA), it 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. Phosphorylation of DARPP-32 at T34 has been used as an index of PKA activation. |

Detection of Rat and Mouse Phospho-DARPP‑32 (T34) by Western Blot. Western blot shows lysates of rat and mouse corpus striata tissue untreated (-) or treated (+) with calcium for 1 hour. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Mouse/Rat Phospho-DARPP‑32 (T34) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2847), followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-DARPP‑32 (T34) at approximately 32 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. |
