Efficient production of recombinant human transcription factor IIE.
Transcription factor IIE (TFIIE) is a general initiation and promoter escape factor for RNA polymerase II composed of p56 (TFIIE-alpha) and p34 (TFIIE-beta) subunits. Our laboratories experienced difficulty producing adequate quantities of recombinant human TFIIE-alpha for in vitro studies using available clones. We therefore re-engineered the TFIIE subunit production vectors and tested various Escherichia coli host strains to optimize expression. We report a much-improved system for production of pure, soluble, and active TFIIE complex for in vitro studies.
