Crystal structure of human Fanconi Anemia protein E C-terminal domain
Contents |
Overview
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.
