ERCC1 is a non-catalytic component of a structure-specific DNA repair endonuclease responsible for the 5'-incision during DNA repair. It is responsible, in conjunction with SLX4, for the first step in the repair of interstrand cross-links (ICL). It participates in the processing of anaphase bridge-generating DNA structures, which consist in incompletely processed DNA lesions arising during S or G2 phase, and can result in cytokinesis failure. ERCC1 is also required for homology-directed repair (HDR) of DNA double-strand breaks, in conjunction with SLX4. (Uniprot)
