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 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).

DISC1 synthetic peptide (coupled to KLH) containing amino acid residues 740 to 753 from mouse DISC1. This peptide sequence is well conserved in rat DISC1, but has 7 amino acid differences with the conserved site in human DISC1.

This antibody was affinity purified using DISC1 (a.a. 740-753) peptide (without carrier). The antibody detects a 100 kDa* protein corresponding to the molecular mass of DISC1 on SDS-PAGE immunoblots of mouse brain and rat PC12 cells.

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