Abstract

SUMMARY Fanconi anemia (FA) is a human genetic disease characterized by chromosome instability, cancer predisposition, and cellular hypersensitivity to DNA crosslinking agents. The FA pathway regulates the repair of DNA crosslinks. A critical step in this pathway is the monoubiquitination and deubiquitination of FANCD2. Deubiquitination of FANCD2 is mediated by the ubiquitin protease, USP1. Here, we demonstrate that targeted deletion of mouse Usp1 results in elevated perinatal lethality, male infertility, crosslinker hypersensitivity, and a FA phenotype. Usp1−/− mouse embryonic fibroblasts had heightened levels of monoubiquitinated Fancd2 in chromatin. Usp1−/− cells exhibited impaired Fancd2 foci assembly and a defect in homologous recombination repair. Double knockout of Usp1 and Fancd2 resulted in a more severe phenotype than either single knockout. Our results indicate that mouse Usp1 functions downstream in the FA pathway. Deubiquitination is a critical event required for Fancd2 nuclear foci assembly, release from chromatin, and function in DNA repair.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
