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.
In molecular biology and genetics, transcription coregulators are proteins that interact with transcription factors to either activate or repress the transcription of specific genes. [1] Transcription coregulators that activate gene transcription are referred to as coactivators while those that repress are known as corepressors .
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 ...
corepressor – a protein that works with transcription factors to decrease the rate of gene transcription In molecular biology and genetics , transcriptional regulation is the means by which a cell regulates the conversion of DNA to RNA ( transcription ), thereby orchestrating gene activity .
Dr1-associated corepressor is a protein that in humans is encoded by the DRAP1 gene. [ 5 ] [ 6 ] Transcriptional repression is a general mechanism for regulating transcriptional initiation in organisms ranging from yeast to humans.

Nuclear DNA is normally wrapped tightly around histones, making it hard or impossible for the transcription machinery to access the DNA. This association is due primarily to the electrostatic attraction between the DNA and histones as the DNA phosphate backbone is negatively charged and histones are rich in lysine residues, which are positively charged. [10]
Well, it comes down to simple biology. Natalie Rizzo, M.S., RD, author of Planted Performance and founder of Greenletes, shares, “Gentle movement, like walking, may reduce bloating after a meal ...
