Example sentences for: corepressor
How can you use “corepressor” in a sentence? Here are some example sentences to help you improve your vocabulary:
Similar agonist-dependent interactions could be observed between ERβ and the alternate NR corepressor SMRT in vitro (Fig.
In other cases, however, the balance of coactivator and corepressor recruitment is regulated by direct competition for the AF-2 surface, rather than ligand-dependent coregulator exchange.
The finding that estrogens suppress N-CoR binding to ERα [ 39 ] , but promote N-CoR binding to ERβ represents the first demonstration of a corepressor that shows completely distinct modes of hormone-dependent interaction with the ER isoforms.
Other NR coactivators include TRAP220 [ 7 ] , which is part of a larger complex (TRAP/DRIP/SMCC/mediator) that contacts the basal transcription machinery and PGC-1 [ 8 ] , a cold inducible coactivator that binds CBP and SRC-1 and proteins involved in RNA processing [ 9 ] . NR corepressors include NR corepressor (N-CoR) and silencing mediator of retinoid and thyroid responsive transcription (SMRT) [ 4 ] . Both N-CoR and SMRT repress transcription, at least in part, by binding to histone de-acetylases (HDACs) either directly or indirectly through other corepressor complex components.
Generally, NR transcriptional activity is dictated by the balance between coactivator and corepressor recruitment, and one of the most important factors that influences this balance is the absence or presence of agonist ligands (reviewed in [ 4 ] ). Unliganded NRs such as thyroid (TRs) and retinoid receptors (RARs) bind corepressors, and ligand promotes release of corepressor and subsequent binding of coactivators.
