| Biochem/physiol Actions: | The human Transcription Factor IIE (TFIIE) is composed of 56 kDa ( α) and 34 kDa ( β) subunits and is shown to be a heterotetramer. The 56-kDa subunit contains a region similar to a zinc-binding domain and a region sharing homology with the catalytic loop of a kinase domain. TFIIE binds to RNA polymerase II in solution and joins the pre-initiation complex probably concomitant with RNA polymerase II and TFIIF. |
