Abstract

Fanconi anemia (FA) is a human autosomal recessive cancer susceptibility disorder characterized by cellular sensitivity to mitomycin C and ionizing radiation. Although six FA genes (for subtypes A, C, D2, E, F, and G) have been cloned, their relationship to DNA repair remains unknown. In the current study, we show that a nuclear complex containing the FANCA, FANCC, FANCF, and FANCG proteins is required for the activation of the FANCD2 protein to a monoubiquitinated isoform. In normal (non-FA) cells, FANCD2 is monoubiquitinated in response to DNA damage and is targeted to nuclear foci (dots). Activated FANCD2 protein colocalizes with the breast cancer susceptibility protein, BRCA1, in ionizing radiation-induced foci and in synaptonemal complexes of meiotic chromosomes. The FANCD2 protein, therefore, provides the missing link between the FA protein complex and the cellular BRCA1 repair machinery. Disruption of this pathway results in the cellular and clinical phenotype common to all FA subtypes.

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.
