Anti-TFIIB: Monoclonal Transcription Factor II B Antibody (48C6)


BACKGROUND Transcription Factor II B (TF IIB) is an essential component of the RNA polymerase II (Pol II) machinery that acts as a bridge between the TATA-binding protein (TBP) and Pol II.1 The C-terminal domain of TFIIB interacts with the TBP-TATA complex, whereas the N-terminal domain is required for the assembly of TFIIF and Pol II into the preinitiation complex. It is involved in the selection of the transcription start site: mutations in TFIIB cause a shift in the transcription start site.2 In addition, TFIIB interacts with certain TBP-associated factors (TAFs) in vitro, and these interactions might contribute to recruitment or stable association of TFIIB in the context of an active transcription complex.3
