== Function ==

[[http://www.uniprot.org/uniprot/TBP1_ARATH TBP1_ARATH]] General transcription factor that functions at the core of the DNA-binding multiprotein factor TFIID. Binding of TFIID to the TATA box is the initial transcriptional step of the pre-initiation complex (PIC), playing a role in the activation of eukaryotic genes transcribed by RNA polymerase II. [[http://www.uniprot.org/uniprot/TF2B_HUMAN TF2B_HUMAN]] General factor that plays a major role in the activation of eukaryotic genes transcribed by RNA polymerase II.

== Publication Abstract from PubMed ==

The crystal structure of the transcription factor IIB (TFIIB)/TATA box-binding protein (TBP)/TATA-element ternary complex is described at 2.7 A resolution. Core TFIIB resembles cyclin A, and recognizes the preformed TBP-DNA complex through protein-protein and protein-DNA interactions. The amino-terminal domain of core TFIIB forms the downstream surface of the ternary complex, where it could fix the transcription start site. The remaining surfaces of TBP and the TFIIB can interact with TBP-associated factors, other class II initiation factors, and transcriptional activators and coactivators.
