CATEGORY

DNA associated

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
	intracellular,nucleus,nucleoplasm
	intracellular,nucleus,chromatin/chromosome,telomere

basic FUNCTION	cleaving at duplex-single-stranded DNA junctions, making an incision on the 5' side of the lesion in nucleotide excision repair
	playing a role in removal of long non-homologous tails during targeted homologous recombination
	playing an essential role for DNA binding
	playing a role after creation of a double strand break for full activation of the Fanconi anemia pathway
	participates in the Fanconi anemia pathway of cross-link repair
	needed for stabilizing and enhancing ERCC4 endonuclease activity
	new role for ERCC1 distinct from its known function in DNA repair, which may be independent of XRCC4 and its role in mitotic progression may be critical during development
	removes cisplatin-induced DNA adducts and has been related with prognosis and cisplatin response
	ERCC1/ERCC4 is a heterodimeric, structure-specific endonuclease that cleaves single-stranded/double-stranded DNA junctions and has roles in nucleotide excision repair (NER), interstrand crosslink (ICL) repair, homologous recombination, and possibly other pathways
	DCLRE1C and ERCC4-ERCC1 can also induce stalled DNA replication forks cleavage through non-epistatic pathways all along S and G2 phases of the cell cycle

CELLULAR PROCESS	nucleotide, recombination
	nucleotide, repair, nucleotide excision repair

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component	forming a structure specific DNA endonuclease complex with ERCC4/XPF at sites of DNA damage, required for completion of homologous recombination at DNA replication forks stalled by inter-strand cross-links
	complexing with XPA (complex essential for nucleotide excision repair activity)

INTERACTION

DNA

binding

RNA

small molecule

protein	collaboration between DCLRE1A and ERCC4-ERCC1 is necessary to initiate ICL repair in replicating human cells
	interaction between ERCC1 and XPA is essential for a successful NER function

ANIMAL & CELL MODELS

	Ercc1-knockout mice, survive for up to 4 weeks after birth
	Ercc1 deficient mice show severe growth retardation associated with premature replicative senescence leading to liver failure and death at four weeks of age
