UIMC1 (RAP80) is recruited to DNA double-strand breaks (DSBs) through the interaction of its UIM (ubiquitin interaction motif) region with H2AFX (H2AX) ubiquitinated by RNF8 and RNF168 (Huen et al. 2007, Wang and Elledge 2007, Kolas et al. 2007, Mailand et al. 2007). A simultaneous interaction with FAM175A (Abraxas) through the AIR (Abraxas-interaction region) domain of UIMC1 facilitates UIMC1 binding to DNA DSBs. The interaction between UIMC1 and FAM175A and their loading to DNA DSBs is independent of BRCA1 (Wang et al. 2007, Wang and Elledge 2007).
