Fanconi Anaemia (FA) is a cancer predisposition disorder characterized by, spontaneous chromosome breakage and high cellular sensitivity to genotoxic, agents. In response to DNA damage, a multi-subunit assembly of FA, proteins, the FA core complex, monoubiquitinates the downstream FANCD2, protein. The FANCE protein plays an essential role in the FA process of, DNA repair as the FANCD2-binding component of the FA core complex. Here we, report a crystallographic and biological study of human FANCE. The first, structure of a FA protein reveals the presence of a repeated helical motif, that provides a template for the structural rationalization of other, proteins defective in Fanconi Anaemia. The portion of FANCE defined by our, crystallographic analysis is sufficient for interaction with FANCD2, yielding structural information into the mode of FANCD2 recruitment to the, FA core complex. Disease-associated mutations disrupt the FANCE-FANCD2, interaction, providing structural insight into the molecular mechanisms of, FA pathogenesis.

[https://www.uniprot.org/uniprot/FANCE_HUMAN FANCE_HUMAN] Defects in FANCE are a cause of Fanconi anemia complementation group E (FANCE) [MIM:[https://omim.org/entry/600901 600901]. A disorder affecting all bone marrow elements and resulting in anemia, leukopenia and thrombopenia. It is associated with cardiac, renal and limb malformations, dermal pigmentary changes, and a predisposition to the development of malignancies. At the cellular level it is associated with hypersensitivity to DNA-damaging agents, chromosomal instability (increased chromosome breakage) and defective DNA repair.<ref>PMID:11001585</ref>

Fanconi Anaemia (FA) is a cancer predisposition disorder characterized by spontaneous chromosome breakage and high cellular sensitivity to genotoxic agents.

The FANCE protein plays an essential role in the FA process of DNA repair as the FANCD2-binding component of the FA core complex. Here we report a crystallographic and biological study of human FANCE. The first structure of a FA protein reveals the presence of a repeated helical motif that provides a template for the structural rationalization of other proteins defective in Fanconi Anaemia. The portion of FANCE defined by our crystallographic analysis is sufficient for interaction with FANCD2, yielding structural information into the mode of FANCD2 recruitment to the FA core complex. Disease-associated mutations disrupt the FANCE-FANCD2 interaction, providing structural insight into the molecular mechanisms of FA pathogenesis.
