Description:
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. Here it is shown that the archaebacterium Pyrococcus woesei expresses a protein with structural and functional similarity to eukaryotic TBP molecules. This suggests that TBP's role in transcription was established before the archaebacterial and eukaryotic lineages diverged and that the transcription systems of archaebacteria and eukaryotes are fundamentally homologous.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowlands, T -- Baumann, P -- Jackson, S P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 May 27;264(5163):1326-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome/CRC Institute, Cambridge, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8191287" target="_blank"〉PubMed〈/a〉
