The Fanconi anemia (FA) pathway is critical for the cellular response to toxic
DNA interstrand crosslinks (ICLs). Using a biochemical purification strategy, we
identified UHRF1 as a protein that specifically interacts with ICLs in vitro and
in vivo. Reduction of cellular levels of UHRF1 by RNAi attenuates the FA pathway
and sensitizes cells to mitomycin C. Knockdown cells display a drastic reduction
in FANCD2 foci formation. Using live-cell imaging, we observe that UHRF1 is
rapidly recruited to chromatin in response to DNA crosslinking agents and that
this recruitment both precedes and is required for the recruitment of FANCD2 to
ICLs. Based on these results, we describe a mechanism of ICL sensing and propose
that UHRF1 is a critical factor that binds to ICLs. In turn, this binding is
necessary for the subsequent recruitment of FANCD2, which allows the DNA repair
process to initiate.
