Tata-binding protein (tbp)
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)). 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.
