The rare hereditary disorder Fanconi anemia (FA) can be caused by mutations in components of the FA core complex (FancA/B/C/E/F/G/L/M), a key regulator FancD2, the breast cancer susceptibility protein BRCA2/FancD1, or the newly identified FancJ/BRIP1 helicase. By performing yeast two-hybrid (Y2H) screens using N-terminal chicken (ch) FancD2 as a bait, we have identified chFancL, the likely ubiquitin E3 ligase subunit of the FA core complex. We also found that ectopically expressed FancD2 and FancL co-immunoprecipitated in 293T cells, and this interaction was dependent on the PHD domain of FancL. FANCL-disrupted chicken DT40 cells displayed defects in both FancD2 monoubiquitination and focus formation. Importantly, cell lines lacking the FANCL or FANCD2 genes, or carrying a "knock-in" mutation of the FancD2 monoubiquitination site (where the Lys 563 residue is changed to Arg), displayed quantitatively identical defects in the repair of I-SceI-induced chromosomal breaks by homologous recombination (HR). These data establish the role of FANCL and FancD2 monoubiquitination in HR repair.
