ERCC4（ERCC excision repair 4， endonuclease catalytic subunit），癌症关联基因，基因ID：2072，该基因编码的蛋白质与ERCC1形成复合物，参与核苷酸切除修复过程中的5'切口。该复合物是一种与EME1相互作用的结构特异性DNA修复内切酶。该基因缺陷是着色性干皮病互补组F（xp-f）或着色性干皮病VI（xp6）的原因。[由Refseq提供，2009年3月]The protein encoded by this gene forms a complex with ERCC1 and is involved in the 5' incision made during nucleotide excision repair. This complex is a structure specific DNA repair endonuclease that interacts with EME1. Defects in this gene are a cause of xeroderma pigmentosum complementation group F (XP-F)， or xeroderma pigmentosum VI (XP6).[provided by RefSeq， Mar 2009]。
