CPD LESION CONTAINING RNA POLYMERASE II ELONGATION COMPLEX B
Overview
Cells use transcription-coupled repair (TCR) to efficiently eliminate DNA, lesions such as ultraviolet light-induced cyclobutane pyrimidine dimers, (CPDs). Here we present the structure-based mechanism for the first step, in eukaryotic TCR, CPD-induced stalling of RNA polymerase (Pol) II. A CPD, in the transcribed strand slowly passes a translocation barrier and enters, the polymerase active site. The CPD 5'-thymine then directs uridine, misincorporation into messenger RNA, which blocks translocation., Artificial replacement of the uridine by adenosine enables CPD bypass;, thus, Pol II stalling requires CPD-directed misincorporation. In the, stalled complex, the lesion is inaccessible, and the polymerase, conformation is unchanged. This is consistent with nonallosteric, recruitment of ... [(full description)]
