DISC1 Phospho-Regulation Antibody Kit

Antibody Sampler Kit



Disrupted in schizophrenia 1 (DISC1) is a multifunctional scaffold protein that has important roles in neurodevelopment. DISC1 is expressed in both neuronal progenitor cells and postmitotic neurons in the developing cerebral cortex. DISC1 can interact with both centrosomal proteins and dynein-motor related proteins. In addition, DISC1 interacts with and inhibits the kinase GSK-3β to enable Wnt activation of β-catenin–mediated gene transcription and neuron proliferation. These functions of DISC1 may be regulated by post-translational modification. PKA and CDK5 can phosphorylate Ser-710, and a non-phosphorylatable Ser-710 mutant shows decreased interaction with the centrosomal proteins, BBS1 and BBS4, while a constituitively phosphorylated Ser-710 mutant shows increased interaction with these proteins. During neuronal progenitor cell proliferation, DISC1 phosphorylation at Ser-710 is low and the interaction with GSK-3β is enhanced. By contrast, DISC1 phosphorylation is increased, association with GSK-3β is decreased, and interaction with BBS1 is enhanced during postmitotic neuron migration.

Western blot of DISC1 phosphorylation in PC12 cells untreated (lanes 1 & 3) or treated with calyculin A (100 nm) for 30 min (lanes 2 & 4). The blots were probed with DP3041 anti-DISC1 (a.a. 740-753) (lanes 1 & 2) or DP3061 anti-DISC1 (Ser-710) (lanes 3 & 4).

Western blot of DISC1 in mouse brain (lanes 1 & 3) and rat PC12 cells (lanes 2 & 4). The blots were probed with DP3021 anti-DISC1 (a.a. 740-753) (lanes 1 & 2) and DP3041 anti-DISC1 (a.a. 740-753) (lanes 3 & 4).

Rabbit polyclonal antibodies are supplied in phosphate-buffered saline (PBS), 50% glycerol, 1 mg/ml BSA, and 0.05% sodium azide. The secondary reagents are supplied in the same buffer without azide, and the peptides are supplied in PBS and 0.05% sodium azide. Store all at –20°C. Stable for 1 year.

The products are are safely shipped at ambient temperature for both domestic and international shipments. Each product is guaranteed to match the specifications as indicated on the corresponding technical data sheet. Please store at -20C upon arrival for long term storage.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.

The DISC1 phospho-regulation antibody kit can be used to detect phosphorylation of Ser-710 relative to total DISC1 expression. The kit includes two rabbit polyclonal antibodies to detect total expression of DISC1 and secondary reagents for detection of rabbit polyclonal antibody in western blot or ELISA. In addition, the kit includes peptides for blocking experiments or use as ELISA positive controls.
