abstract = {Disrupted in Schizophrenia 1 (DISC1) is a scaffolding
protein of significant importance for neurodevelopment and a
prominent candidate protein in the pathology of major mental
illness. DISC1 modulates a number of critical neuronal
signaling pathways through protein-protein interactions;
however, the mechanism by which this occurs and how DISC1
causes mental illness is unclear, partly because knowledge
of the structure of DISC1 is lacking. A lack of homology
with known proteins has hindered attempts to define its
domain composition. Here, we employed the high-throughput
Expression of Soluble Proteins by Random Incremental
Truncation (ESPRIT) technique to identify discretely folded
regions of human DISC1 via solubility assessment of tens of
thousands of fragments of recombinant DISC1. We identified
four novel structured regions, named D, I, S, and C, at
amino acids 257–383, 539–655, 635–738, and 691–836,
respectively. One region (D) is located in a DISC1 section
previously predicted to be unstructured. All regions
encompass coiled-coil or α-helical structures, and three
are involved in DISC1 oligomerization. Crucially, three of
these domains would be lost or disrupted by a chromosomal
translocation event after amino acid 597, which has been
strongly linked to major mental illness. Furthermore, we
observed that a known illness-related frameshift mutation
after amino acid 807 causes the C region to form aberrantly
multimeric and aggregated complexes with an unstable
secondary structure. This newly revealed domain architecture
of DISC1, therefore, provides a powerful framework for
understanding the critical role of this protein in a variety
of devastating mental illnesses.},
