The corepressor Rcorhas been linked biochemically to hematopoiesis, but its function in vivo remains unknown.

Corepressors often act by altering chromatin structure and modifications. We show that mice deleted for Rcorare . To investigate co-repressor activity in the context of this well defined signalling pathway, we have analysed the genome-wide binding profile of . SMRT and NCoR are corepressor paralogs that help mediate transcriptional repression by a variety of transcription factors, including the . SMILE is an insulin-inducible corepressor that suppresses hepatic gluconeogenesis by opposing the action of PGC-1α. Many nuclear hormone receptors (NHRs) actively repress the expression of their primary response genes through the recruitment of transcriptional corepressor.
