Crystal structure of the C-terminal segment of FANCM in complex with FAAP24

Template:ABSTRACT PUBMED 24003026

Disease

[FANCM_HUMAN] Fanconi anemia. The disease is caused by mutations affecting the gene represented in this entry.

Function

[FANCM_HUMAN] ATPase required for FANCD2 ubiquitination, a key reaction in DNA repair. Binds to ssDNA but not to dsDNA. Recruited to forks stalled by DNA interstrand cross-links, and required for cellular resistance to such lesions.[1] [2] [REFERENCE:7][REFERENCE:8] [FAP24_HUMAN] Plays a role in DNA repair through recruitment of the FA core complex to damaged DNA. Regulates FANCD2 monoubiquitination upon DNA damage. Induces chromosomal instability as well as hypersensitivity to DNA cross-linking agents, when repressed. Targets FANCM/FAAP24 complex to the DNA, preferentially to single strand DNA.

About this Structure
