Example sentences for: corepressor

How can you use “corepressor” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • NRs generally interact with the corepressors N-CoR and SMRT either in the absence of ligand, or in the presence of receptor antagonists, and agonists promote corepressor release [ 4 ] . In this study, we demonstrated that ERβ binds to N-CoR in the presence of ER agonists such as estradiol and DES and the phytoestrogens genistein and coumestrol, but not in the presence of SERMs.

  • 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.

  • Similar agonist-dependent interactions could be observed between ERβ and the alternate NR corepressor SMRT in vitro (Fig.

  • Thus, corepressor complex HDACs must play an unspecified role in restricting the transcriptional activity of both ERβ and, in particular, the ERβ-LBD.

  • The nuclear receptor (NR) family comprises 48 structurally related transcription factors, many of which require their cognate ligand for activity [ 1 2 3 ] . The NRs regulate transcription by binding to response elements in the promoters of target genes and acting as scaffolds for the assembly of large coactivator and corepressor complexes [ 4 ] . NR coactivators include the p160s (including GRIP1/TIF-2, SRC-1 and AIB1/ACTR/pCIP).
