a structure-specific DNA repair endonuclease responsible for the 5'-incision during DNA excision repair. Belongs to the ERCC1/RAD10/SWI10 family. Heterodimer composed of ERCC1 and XPF/ERRC4. Defects in ERCC1 are the cause of cerebro-oculo-facio-skeletal syndrome type 4, a degenerative autosomal recessive disorder of prenatal onset affecting the brain, eye and spinal cord. After birth, it leads to brain atrophy, hypoplasia of the corpus callosum, hypotonia, cataracts, microcornea, optic atrophy, progressive joint contractures and growth failure. Facial dysmorphism is a constant feature. Abnormalities of the skull, eyes, limbs, heart and kidney also occur. Low levels of this protein are associated with increased sensitivity to cisplatin. The overall survival of non-small cell lung cancer patients with single-nucleotide polymorphisms at codon 118 receiving platinum-based chemotherapy was significantly improved.
