'''TATA-BINDING PROTEIN/TRANSCRIPTION FACTOR (II)B/BRE+TATA-BOX COMPLEX FROM PYROCOCCUS WOESEI'''<br />


==Overview==
==TATA-BINDING PROTEIN/TRANSCRIPTION FACTOR (II)B/BRE+TATA-BOX COMPLEX FROM PYROCOCCUS WOESEI==
Recently the definition of the metazoan RNA polymerase II and archaeal, core promoters has been expanded to include a region immediately upstream, of the TATA box called the B recognition element (BRE), so named because, eukaryal transcription factor TFIIB and its archaeal orthologue TFB, interact with the element in a sequence-specific manner. Here we present, the 2.4-A crystal structure of archaeal TBP and the C-terminal core of TFB, (TFB(c)) in a complex with an extended TATA-box-containing promoter that, provides a detailed picture of the stereospecific interactions between the, BRE and a helix-turn-helix motif in the C-terminal cyclin repeat of, TFB(c). This interaction is important in determining the level of basal, transcription and explicitly defines the direction of transcription.

== Function ==
[https://www.uniprot.org/uniprot/TBP_PYRWO TBP_PYRWO] General factor that plays a role in the activation of archaeal genes transcribed by RNA polymerase. Binds specifically to the TATA box promoter element which lies close to the position of transcription initiation.

== Publication Abstract from PubMed ==
Recently the definition of the metazoan RNA polymerase II and archaeal core promoters has been expanded to include a region immediately upstream of the TATA box called the B recognition element (BRE), so named because eukaryal transcription factor TFIIB and its archaeal orthologue TFB interact with the element in a sequence-specific manner. Here we present the 2.4-A crystal structure of archaeal TBP and the C-terminal core of TFB (TFB(c)) in a complex with an extended TATA-box-containing promoter that provides a detailed picture of the stereospecific interactions between the BRE and a helix-turn-helix motif in the C-terminal cyclin repeat of TFB(c). This interaction is important in determining the level of basal transcription and explicitly defines the direction of transcription.
