WitrynaAccurate computational identification of promoters remains one challenge as like key DNA regulatory regions have variable structures composed of operative motifs that provide gene-specific initiation of transcription. By this paper we utilize Convolutional Neural Networks (CNN) to analyze sequence characteristics of prokaryotic and … Witryna27 cze 2011 · TATA box binding protein (TBP) TBP is the founding member of the family and is involved in transcription by all of the three major RNA polymerases (I, II and III) in eukaryotes [ 4 ]. It is conserved from archea to man. The primary structure of TBP consists of two major domains.

Witryna27 maj 1994 · 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. WitrynaDistinct transcriptional programs with TBP vs. TRF2 system factors. TBP can activate transcription via the TATA-box motif, and both TBP and the TATA box are conserved in Archaea and eukaryotes (Kosa et al. 1997; Patikoglou et al. 1999).TBP binds to the TATA box with its core region, which consists of two structurally repeated domains …
