... late steps of the process. For example, early in the NER process, RPA assists TFIIH in the opening of the DNA helix around the damage site [36]. Further-more, in the presence of the XPA minimal ... sites.Taken together, these findings suggest that the struc-tural properties of DNA-damaged substrates, whetherintrinsic or the result of protein binding, function in the recruitment of the XPC–hHR23B ... trimerizationcore, which consists of the C-terminal part of RPA70, the N-terminal part of RPA32,and the N-terminal part of RPA14 (PDBentry: 1LIO).
