Description

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.

Physical form

Clear and colorless frozen liquid solution

Preparation Note

Use a manual defrost freezer and avoid repeated freeze-thaw cycles. While working, please keep sample on ice.
