FA protein FANCI has been identified as an ATM/ATR kinase substrate required for cellular resistance to mitomycin C. FANCI shares sequence similarity with FANCD2, likely evolving from a common ancestral gene. The FANCI protein associates with FANCD2 and, together, as the FANCI FANCD2 (ID) complex, localize to chromatin in response to DNA damage. FANCD2-FANCI interdependent monoubiquitination is important for the maintenance of ubiquitin on the other, indicating the existence of a dual ubiquitin-locking mechanism required for ID complex function and hence DNA repair.
