  2. Corepressor - Wikipedia

    en.wikipedia.org/wiki/Corepressor

    In genetics and molecular biology, a corepressor is a molecule that represses the expression of genes. [1] In prokaryotes, corepressors are small molecules whereas in eukaryotes, corepressors are proteins. A corepressor does not directly bind to DNA, but instead indirectly regulates gene expression by binding to repressors.

  3. Transcription coregulator - Wikipedia

    en.wikipedia.org/wiki/Transcription_coregulator

    Corepressor proteins also bind to the surface of the ligand binding domain of nuclear receptors, but through a LXXXIXXX(I/L) motif of amino acids (where L = leucine, I = isoleucine and X = any amino acid). [7] In addition, compressors bind preferentially to the apo (ligand free) form of the nuclear receptor (or possibly antagonist bound receptor).

  4. Coactivator (genetics) - Wikipedia

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

    The binding of a ligand hormone causes the corepressor to dissociate and a coactivator is recruited. The activator bound coactivator recruits RNA polymerase and other transcription machinery that then begins transcribing the target gene.

  5. Nuclear receptor coregulators - Wikipedia

    en.wikipedia.org/wiki/Nuclear_receptor_coregulators

    The ability of nuclear receptors to alternate between activation and repression in response to specific molecular cues, is now known to be attributable in large part to a diverse group of cellular factors, collectively termed coregulators and including coactivators and corepressors.

  6. CTBP1 - Wikipedia

    en.wikipedia.org/wiki/CTBP1

    CtBPs have multiple biological roles and appear to be most important in regulating the epithelial to mesenchymal transition, as well as influencing metabolism. They do the latter by binding NADH in preference to NAD+, thereby sensing the NADH/NAD+ ratio. When bound, it undergoes a conformational change that allows it to dimerize and associate ...

  7. Silencer (genetics) - Wikipedia

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

    Furthermore, the NRSF-NRSE complex recruits a transcriptional corepressor known as mSin3. [13] This leads to the activity of histone deacetylase in the region and the repression of the gene. Therefore, studies have revealed the correlation between REST/NRSF and RE1/NRSE in regulating the ANP gene expression in ventricular myocytes. A mutation ...
