DISC1 Phospho-Regulation Antibody Sampler Kit

Background:
Disrupted in schizophrenia 1 (DISC1) is a susceptibility factor for a wide range of mental illnesses, including schizophrenia, mood disorders, and autism. 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.

Buffer/Storage:
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.
