  2. Promoter (genetics) - Wikipedia

    en.wikipedia.org/wiki/Promoter_(genetics)

    Many other elements/motifs may be present. There is no such thing as a set of "universal elements" found in every core promoter. [23] Proximal promoter – the proximal sequence upstream of the gene that tends to contain primary regulatory elements Approximately 250 base pairs upstream of the start site; Specific transcription factor binding sites

  3. Upstream activating sequence - Wikipedia

    en.wikipedia.org/wiki/Upstream_Activating_Sequence

    An upstream activating sequence or upstream activation sequence (UAS) is a cis-acting regulatory sequence found in yeast like Saccharomyces cerevisiae. It is distinct from the promoter and increases the expression of a neighbouring gene .

  4. Pribnow box - Wikipedia

    en.wikipedia.org/wiki/Pribnow_box

    It is also commonly called the -10 sequence or element, because it is centered roughly ten base pairs upstream from the site of initiation of transcription. The Pribnow box has a function similar to the TATA box that occurs in promoters in eukaryotes and archaea : it is recognized and bound by a subunit of RNA polymerase during initiation of ...

  5. B recognition element - Wikipedia

    en.wikipedia.org/wiki/B_recognition_element

    The B recognition element (BRE) is a DNA sequence found in the promoter region of most [clarification needed] genes in eukaryotes and Archaea. [1] [2] The BRE is a cis-regulatory element that is found immediately near TATA box, and consists of 7 nucleotides. There are two sets of BREs: one (BREu) found immediately upstream of the TATA box, with ...

  6. UBTF - Wikipedia

    en.wikipedia.org/wiki/UBTF

    UBTF is a nucleolar phosphoprotein with both DNA binding and transactivation domains. Sequence-specific DNA binding to the core and upstream control elements of the human rRNA promoter is mediated through several HMG boxes. [13] [supplied by OMIM] [6] In vertebrates, UBTF plays a crucial role in maintaining rDNA chromatin in a euchromatic state.

  7. Activator (genetics) - Wikipedia

    en.wikipedia.org/wiki/Activator_(genetics)

    Activator-binding sites may be located very close to the promoter or numerous base pairs away. [2] [3] If the regulatory sequence is located far away, the DNA will loop over itself (DNA looping) in order for the bound activator to interact with the transcription machinery at the promoter site. [2] [3]

  8. Upstream and downstream (transduction) - Wikipedia

    en.wikipedia.org/wiki/Upstream_and_downstream...

    Receptors and ligands exist in many different forms, and only recognize/bond to particular molecules. Upstream extracellular signaling transduce a variety of intracellular cascades. [1] Receptors and ligands are common upstream signaling molecules that dictate the downstream elements of the signal pathway. A plethora of different factors affect ...

  9. Run-off transcription - Wikipedia

    en.wikipedia.org/wiki/Run-off_transcription

    To perform a run-off transcription assay, a gene of interest, including the promoter, is cloned into a plasmid. [4] The plasmid is digested at a known restriction enzyme cut site downstream from the transcription start site such that the expected mRNA run-off product would be easily separated by gel electrophoresis .
