A new basal promoter element recognized by RNA polymerase core enzyme
Bacterial promoters are recognized by RNA polymerase (RNAP) σ subunit, which specifically interacts with the -10 and -35 promoter elements. Here, we provide evidence that the β' zipper, an evolutionarily conserved loop of the largest subunit of RNAP core, interacts with promoter spacer, a DNA segment that separates the -10 and -35 promoter elements, and facilitates the formation of stable close...
متن کاملThe RNA polymerase II core promoter.
The events leading to transcription of eukaryotic protein-coding genes culminate in the positioning of RNA polymerase II at the correct initiation site. The core promoter, which can extend ~35 bp upstream and/or downstream of this site, plays a central role in regulating initiation. Specific DNA elements within the core promoter bind the factors that nucleate the assembly of a functional preini...
متن کاملThe punctilious RNA polymerase II core promoter.
The signals that direct the initiation of transcription ultimately converge at the core promoter, which is the gateway to transcription. Here we provide an overview of the RNA polymerase II core promoter in bilateria (bilaterally symmetric animals). The core promoter is diverse in terms of its composition and function yet is also punctilious, as it acts with strict rules and precision. We addit...
متن کاملCore promoter-selective RNA polymerase II transcription.
The initiation of mRNA synthesis in eukaryotic cells is a complex and highly regulated process that requires the assembly of general transcription factors and RNAP II (RNA polymerase II; also abbreviated as Pol II) into a pre-initiation complex at the core promoter. The core promoter is defined as the minimal DNA region that is sufficient to direct low levels of activator-independent (basal) tr...
متن کاملNew core promoter element in RNA polymerase II-dependent transcription: sequence-specific DNA binding by transcription factor IIB.
A sequence element located immediately upstream of the TATA element, and having the consensus sequence 5'-G/C-G/C-G/A-C-G-C-C-3', affects the ability of transcription factor IIB to enter transcription complexes and support transcription initiation. The sequence element is recognized directly by the transcription factor IIB. Recognition involves alpha-helices 4' and 5' of IIB, which comprise a h...
