Transcription factor II B (TF_IIB) is one of several general transcription factors that make up the RNA polymerase II preinitiation complex.^[1] It is encoded by the TFIIB gene.^[2]^[3]

Transcription factor IIB localizes to the nucleus where it forms a complex (the DAB complex) with transcription factors IID and IIA. The protein serves as a bridge between IID, the factor that initially recognizes the promoter sequence, and RNA polymerase II.^[4] It is involved in the selection of the transcription start site: mutations in TFIIB cause a shift in the transcription start site.^[5]

[edit] Interactions

Transcription Factor II B has been shown to interact with CREB-binding protein,^[6]^[7] GTF2H4,^[8] TATA-binding protein,^[8]^[9] POLR2A,^[8] TAF11,^[8] GTF2F1^[8]^[10] and C-jun.^[11]
