WebMay 27, 1994 · The TATA-binding protein TBP appears to be essential for all transcription in eukaryotic cell nuclei, which suggests that its function was established early in …
In molecular biology, the TATA box (also called the Goldberg–Hogness box) is a sequence of DNA found in the core promoter region of genes in archaea and eukaryotes. The bacterial homolog of the TATA box is called the Pribnow box which has a shorter consensus sequence. The TATA box is considered a non-coding DNA sequence (also known as a cis … The TATA-binding protein (TBP) is a general transcription factor that binds specifically to a DNA sequence called the TATA box. This DNA sequence is found about 30 base pairs upstream of the transcription start site in some eukaryotic gene promoters. See more TBP is a member of a small gene family of TBP-related factors. The first TBP-related factor (TRF/TRF1) was identified in the fruit fly Drosophila, but appears to be fly or insect-specific. Subsequently TBPL1/TRF2 was found in the … See more TBP is a subunit of the eukaryotic general transcription factor TFIID. TFIID is the first protein to bind to DNA during the formation of the transcription preinitiation complex of RNA polymerase II (RNA … See more The TATA-box binding protein (TBP) is required for the initiation of transcription by RNA polymerases I, II and III, from promoters with or without a TATA box. In the presence of a TATA-less promoter, TBP binds with the help of TBP-associated factors (TAFs). … See more • GeneReviews/NCBI/NIH/UW entry on Spinocerebellar Ataxia Type 17 • Interactive TBP Structure at massey.ac.nz See more When TBP binds to a TATA box within the DNA, it distorts the DNA by inserting amino acid side-chains between base pairs, partially … See more TATA-binding protein has been shown to interact with: • BRF1, • BTAF1, • C-Fos, See more The C-terminal core of TBP (~180 residues) is highly conserved and contains two 88-amino acid repeats that produce a saddle-shaped structure that straddles the DNA; this region See more
WebThe TBP represents one of the few protein families that use an extended β -sheet to bind target DNA. TBP is a transcription factor that recognizes and binds to a TATA-box … WebEukaryotic RNA polymerases require multiple initiation factors to start transcription. All the RNA polymerases use a TATA box–binding protein, but most of the other initiation …
WebThe TATA-binding protein, TBP, is used by all three RNA polymerases and is therefore central to the process of gene expression. TBP associates with several subsets of …
