The ERCC1-xeroderma pigmentosum group F DNA repair complex

Abstract

In its long nucleotide-chains, the DNA double helix contains the genetic information for ten thousands of proteins. The DNA molecule, however, is subject to constant change. In order to l11ailltaill its integrity, several luechallisms that cope with DNA damage, inflicted byvarious naturally occurring and man-made agents, have evolved. Individuals with the rare genetic disease xeroderma pigmentosum demonstrate the importance of DNA repair systems. These patients carry a defect in proteins that are involved in the removal ofUV-induced damage from the DNA, which results in sun-sensitivity and the frequent occurrence of skin cancers, Hence, studies on DNA repair and human repah' disorders such as xeroderma pigmentosu
