Disrupted-in-schizophrenia-1 (DISC1) is one of major susceptibility factors for a wide range of mental illnesses, including schizophrenia, bipolar disorder, major depression and autism spectrum conditions. DISC1 is located in several subcellular domains, such as the centrosome and the nucleus, and interacts with various proteins, including NudE-like (NUDEL/NDEL1) and activating transcription factor 4 (ATF4)/CREB2. Nevertheless, a role for DISC1 in vivo remains to be elucidated. Therefore, we have generated a Drosophila model for examining normal functions of DISC1 in living organisms. DISC1 transgenic flies with preferential accumulation of exogenous human DISC1 in the nucleus display disturbance in sleep homeostasis, which has been reportedly associated with CREB signaling/CRE-mediated gene transcription. Thus, in mammalian cells, we characterized nuclear DISC1, and identified a subset of nuclear DISC1 that colocalizes with the promyelocytic leukemia (PML) bodies, a nuclear compartment for gene transcription. Furthermore, we identified three functional cis-elements that regulate the nuclear localization of DISC1. We also report that DISC1 interacts with ATF4/CREB2 and a corepressor N-CoR, modulating CRE-mediated gene transcription.

Convergent evidence from genetic linkage, genetic association and biological studies implicates the Disrupted in schizophrenia 1 (DISC1) gene in the etiology and pathophysiology of schizophrenia. We conducted genetic association studies in matched case-control and family sample sets (N=117 families; N=210 case-control pairs), testing polymorphisms across DISC1 and DISC1 interacting genes: LIS1, NUDEL, FEZ1 and PDE4B. We found that DISC1 variants, particularly in the exon 9/intron 9/intron 10 region of the gene, may be associated with risk for schizophrenia in our sample population. There was no strong evidence for association with LIS1, NUDEL, FEZ1 and PDE4B. Gene-gene interaction analyses and mRNA quantification in post-mortem brains from schizophrenia patients and control subjects did not reveal significant differences.
