Isolation of a cDNA encoding a UV-damaged DNA binding factor defective in xeroderma pigmentosum group E cells
Abstract
XPE binding factor (XPE-BF) is deficient in a subset of patients from xeroderma pigmentosum complementation group E. Binding activity copurifies with a 125 kDa polypeptide (p125) that binds to DNA damaged by ultraviolet (UV) radiation and many other agents. We isolated cDNA encoding a polypeptide with a predicted amino acid sequence that matched the sequences of eleven tryptic peptides derived from digestion of XPE-BF purified from human placenta. In vitro transcription and translation of the cDNA yielded a polypeptide of 125 kDa that bound specifically to UV-damaged DNA. Therefore the cDNA encodes either all or the major component of XPE-BF.
