| Post Translational Modifications | Monoubiquitinated by FANCL on Lys-523 during S phase and upon genotoxic stress. Deubiquitinated by USP1 as cells enter G2/M, or once DNA repair is completed. Monoubiquitination requires the FANCA-FANCB-FANCC-FANCE-FANCF-FANCG-FANCM complex. Ubiquitination is required for binding to chromatin, DNA repair, and normal cell cycle progression. Monoubiquitination is stimulated by DNA-binding. Phosphorylated in response to DNA damage by ATM and/or ATR. Phosphorylation of FANCI promotes ubiquitination of FANCD2, which prevents DNA release from the FANCI-FANCD2 complex. |
| Function | Plays an essential role in the repair of DNA double-strand breaks by homologous recombination and in the repair of interstrand DNA cross-links (ICLs) by promoting FANCD2 monoubiquitination by FANCL and participating in recruitment to DNA repair sites. The FANCI-FANCD2 complex binds and scans double-stranded DNA (dsDNA) for DNA damage.this complex stalls at DNA junctions between double-stranded DNA and single-stranded DNA. Participates in S phase and G2 phase checkpoint activation upon DNA damage. |
