Description

The general transcription factor TFIIE has an essential role in eukaryotic transcription initiation together with RNA polymerase II and other general factors. Human TFIIE consists of two subunits of relative molecular mass 57, 000 (TFIIE-alpha) and 34, 000 (TFIIE-beta) and joins the preinitiation complex after RNA polymerase II and TFIIF. TFIIE-alpha is necessary for transcription initiation together with TFIIE-beta, and recombit TFIIE-alpha can fully replace the natural subunit in an in vitro transcription assay. Its sequence contains several interesting structural motifs (leucine repeat, zinc finger and helix-turn-helix) and sequence similarities to bacterial sigma factors that suggest direct involvement in the regulation of transcription initiation.
