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 .
While this article refers to the historical terms "coactivator" and "corepressor," this distinction is less clear than was at first thought, and it is now known that cell type, cell signaling state and promoter identity can influence the direction of action of any given coregulator. [2]
The mammalian CtBP2 gene produces alternative transcripts encoding two distinct proteins. In addition to the transcriptional repressor (corepressor) discussed above, there is a longer isoform that is a major component of specialized synapses known as synaptic ribbons.
Its operon is an example of a prokaryotic silencer. The three functional genes in this operon are lacZ, lacY, and lacA. [6] The repressor gene, lacI, will produce the repressor protein LacI which is under allosteric regulation. These genes are activated by the presence of lactose in the cell which acts as an effector molecule that binds to LacI ...
For a specific example, dysregulation of CREB-binding protein (CBP)—which acts as a coactivator for numerous transcription factors within the central nervous system (CNS), reproductive system, thymus and kidneys—has been linked to Huntington's disease, leukaemia, Rubinstein-Taybi syndrome, neurodevelopmental disorders and deficits of the ...
