Biochem/physiol Actions
General transcription factor for RNA Polymerase II.
The amino terminal region of TFIIB contains a zinc ribbon fold composed of antiparallel Β strands. Mutational studies show that this domain is required for recruitment of RNA Pol II for transcriptional initiation.
Physical form
Solution in 20 mM Tris-HCl, pH 7.4, 100 mM NaCl, 2 mM DTT, 1 mM EDTA, 0.1% Triton® X-100.
Other Notes
One gel shift unit is the amount of TFIIB required to form 0.2 pmol of TFIIB/TFIID/DNA complex as detected by gel shift.
