CRYSTAL STRUCTURE OF A YEAST TBP/TATA-BOX COMPLEX

Structural highlights

1ytb is a 4 chain structure with sequence from Atcc 18824. The July 2005 RCSB PDB Molecule of the Month feature on TATA-Binding Protein by David S. Goodsell is 10.2210/rcsb_pdb/mom_2005_7. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

[TBP_YEAST] General transcription factor that functions at the core of the DNA-binding general transcription factor complex TFIID. Binding of TFIID to a promoter (with or without TATA element) is the initial step in preinitiation complex (PIC) formation. TFIID plays a key role in the regulation of gene expression by RNA polymerase II through different activities such as transcription activator interaction, core promoter recognition and selectivity, TFIIA and TFIIB interaction, chromatin modification (histone acetylation by TAF1), facilitation of DNA opening and initiation of transcription.^[1] ^[2] ^[3]

Publication Abstract from PubMed

The 2.5 A crystal structure of a TATA-box complex with yeast TBP shows that the eight base pairs of the TATA box bind to the concave surface of TBP by bending towards the major groove with unprecedented severity. This produces a wide open, underwound, shallow minor groove which forms a primarily hydrophobic interface with the entire under-surface of the TBP saddle. The severe bend and a positive writhe radically alter the trajectory of the flanking B-form DNA.
