Tata-binding protein (tbp)
TBP is involved in DNA melting (double strand separation) by bending the DNA by 80° (the AT-rich sequence to which it binds facilitates easy melting). The TBP is an unusual protein in that it binds the minor groove using a β sheet. Another distinctive feature of TBP is a long string of glutamines in the N-terminus of … See more 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 … 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 See more TATA-binding protein has been shown to interact with: • BRF1, • BTAF1, • C-Fos, • C-jun, • EDF1, 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 binds to the TATA box and interacts with transcription factors and regulatory 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 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 unwinding the helix, and doubly kinking it. The distortion is accomplished through a great amount of surface contact … 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 … See more WebRecent evidence indicates that the TATA-binding protein (TBP) is central to transcription by all three eukaryotic RNA polymerases (I, II, and III). Interestingly, the majority of the TBP does not appear to be free protein in vivo. Instead, it is found associated with other factors (TAFs) in multisubunit complexes.

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 evolution. Archaebacteria constitute a kingdom of organisms distinct from eukaryotes and eubacteria. Archaebacterial gene regulatory sequences often map to TATA box-like motifs. WebTBP is a transcription factor that recognizes and binds to a TATA-box sequence that is extremely A/T-rich. TBP consists of two domains separated by a concave anti-parallel 10-stranded β -sheet which covers and binds at the DNA minor-groove (shown in Figure 2 (f)).
WebJan 5, 2001 · The general transcription factor TFIID, which is composed of the TATA box-binding protein (TBP) and a set of TBP-associated factors (TAFs), is crucial for both basal and regulated transcription by RNA polymerase II. The N-terminal small segment of yeast TAF145 (yTAF145) binds to TBP and thereby inhibits TBP function.
