The transcriptional factor TFIIS helps overcome elongation barriers and enhances proofreading by RNA polymerase II. These TFIIS functions may be modulated by the TFIIS zinc ribbon domain through interactions with nucleic acids in the elongation complex. Within this zinc ribbon domain, the dipeptide...
