Fancd2 in vivo interaction network reveals a non-canonical role in mitochondrial function
Bibliographic record
Abstract
Fancd2 is a component of the Fanconi anemia (FA) DNA repair pathway, which is frequently found defective in human cancers. The full repertoire of Fancd2 functions in normal development and tumorigenesis remains to be determined. Here we developed a Flag- and hemagglutinin-tagged Fancd2 knock-in mouse strain that allowed a high throughput mass spectrometry approach to search for Fancd2-binding proteins in different mouse organs. In addition to DNA repair partners, we observed that many Fancd2-interacting proteins are mitochondrion-specific. Fancd2 localizes in the mitochondrion and associates with the nucleoid complex components Atad3 and Tufm. The Atad3-Tufm complex is disrupted in Fancd2-/- mice and those deficient for the FA core component Fanca. Fancd2 mitochondrial localization requires Atad3. Collectively, these findings provide evidence for Fancd2 as a crucial regulator of mitochondrion biosynthesis, and of a molecular link between FA and mitochondrial homeostasis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
