NCOR1 is a large scaffold corepressor that nucleates multiprotein histone-deacetylase complexes to silence transcription at genomic targets specified by nuclear receptors and other DNA-binding factors (PMID:10944117, PMID:12628926). Its defining biochemical activity is allosteric: a deacetylase activating domain (DAD) built around a SANT motif is necessary and sufficient to switch on the otherwise-latent enzymatic activity of HDAC3, and DAD mutations that abolish HDAC3 contact eliminate both HDAC activation and repression (PMID:11509652). Within the ~1.5–2 MDa complex NCOR1 organizes HDAC3 together with the WD-40 proteins TBL1/TBLR1 (which bind histones H2B/H4 and are required for repression by unliganded thyroid hormone receptor) and GPS2 (PMID:12628926, PMID:11931768), and the complex carries additional chromatin-modifying activities including USP44-mediated H2B deubiquitination (PMID:27880911). Recruitment is combinatorial: conserved I/LXXII interaction motifs in NCOR1 engage unliganded TR and orphan receptors such as Rev-erb, while antagonist-bound steroid receptors and diverse factors including BCL-6, the AML1/ETO MYND domain, DAX-1, Kaiso, and MeCP2 tether the complex to specific loci (PMID:11117528, PMID:9824158, PMID:17560331, PMID:9566914, PMID:14527417, PMID:27288453). Once recruited, NCOR1/HDAC3 drives local histone deacetylation that licenses chromatin remodeler SNF2H to compact nucleosomes (PMID:16917504), and acts in long-range repressive chromatin loops at glucocorticoid- and SUMO-GR-dependent negative response elements (PMID:23428870, PMID:26712002, PMID:26712006). NCOR1 activity is gated post-translationally by Akt/PI3K phosphorylation that drives nuclear-to-cytoplasmic redistribution (PMID:12410313), by SUMOylation that enhances repression (PMID:16421255), by proteasomal degradation through Siah2 and RNF20 ubiquitin ligases (PMID:16141343, PMID:31604693), and by selective autophagy via GABARAP binding (PMID:30952864). In vivo, NCOR1 is the principal mediator of thyroid hormone receptor repression in pituitary and liver and the effector of dominant-negative TR mutants in resistance to thyroid hormone (PMID:21987803, PMID:25421714, PMID:23610395), and it controls neural stem cell self-renewal, muscle oxidative metabolism, circadian Bmal1 expression, macrophage lipid handling, and GABAergic-neuron-dependent memory (PMID:12410313, PMID:22078881, PMID:15761026, PMID:31529020, PMID:30664766). Some unliganded-TR genomic repression is NCOR1-independent, indicating it does not account for all corepressor output at TR sites (PMID:28923959).

1998 The BCL-6 POZ domain interacts with N-CoR and SMRT corepressors; this interaction is necessary and sufficient for transcriptional repression by BCL-6; BCL-6 and N-CoR co-localize to punctate nuclear regions; POZ domains from other proteins (PLZF, ZID, GAGA) also interact with N-CoR.

1998 DAX-1 recruits N-CoR to steroidogenic factor 1 (SF-1), functioning as an adaptor molecule that extends corepressor action to DNA-bound nuclear receptors; naturally occurring AHC mutations of DAX-1 permit SF-1-DAX-1 interaction but markedly diminish N-CoR recruitment.

2000 N-CoR exists in two distinct multiprotein complexes (N-CoR-1 and N-CoR-2): N-CoR-1 contains HDAC3, SWI/SNF-related proteins (BRG1, BAF170, BAF155, BAF47/INI1), and corepressor KAP-1; N-CoR-2 contains HDAC1 and HDAC2 and Sin3A complex subunits.

2000 N-CoR contains three receptor interaction domains (IDs), each with a conserved I/LXXII hydrophobic core motif that is required for binding to unliganded TR; the third ID (ID3) may be the most important for TR binding. Substitution of ID isoleucines with leucines does not allow binding to liganded TR, indicating the binding preference for unliganded TR is not determined solely by the identity of conserved hydrophobic residues.

2000 Both SMRT and N-CoR exist in large (~1.5–2 MDa) complexes in HeLa nuclear extracts containing HDAC3 and TBL1 (a WD-40 repeat protein); these complexes bind unliganded thyroid hormone receptors in vitro; injection of antibodies against HDAC3 or SMRT/N-CoR into Xenopus oocytes partially relieves repression by unliganded TR/RXR.

2001 The SMRT and N-CoR corepressors activate HDAC3 through a deacetylase activating domain (DAD) containing one of their SANT motifs; recombinant HDAC3 alone is inactive, but reconstitution with the DAD of either SMRT or N-CoR is necessary and sufficient to activate HDAC3 enzymatic activity; mutations in the DAD that abolish HDAC3 interaction also eliminate HDAC activity reconstitution and the major repression function.

2002 N-CoR is required for neural stem cell self-renewal; FGF2-treated embryonic cortical progenitors from N-CoR knockout mice display impaired self-renewal and spontaneous differentiation into astroglia-like cells. CNTF-induced astroglia differentiation involves PI3K/Akt1-dependent phosphorylation of N-CoR, causing its redistribution from nucleus to cytoplasm; recruitment of protein phosphatase-1 to a specific binding site on N-CoR exerts a reciprocal effect on N-CoR localization.

2003 The purified human N-CoR complex contains 10–12 associated proteins; TBL1/TBLR1 associates with N-CoR through two independent interactions (N-terminal region with RD1, C-terminal WD-40 repeats with RD4); TBL1/TBLR1 bind histones H2B and H4 in vitro; siRNA knockdown shows HDAC3 is essential and TBL1/TBLR1 are functionally redundant but essential for repression by unliganded TR.

2010 Crystal structure of Rev-erbalpha ligand-binding domain bound to an N-CoR interaction domain 1 (ID1) peptide reveals an unprecedented antiparallel beta-sheet interaction plus an alpha-helix out of register by four residues compared to ID2 structures; heme and ID1 peptide induce substantially different LBD conformational changes, suggesting Rev-erbalpha can mediate repression via ID1 binding independently of heme. X-ray crystallography, structural comparison Nature structural & molecular biology High 20581824
2010 ERs recruit SMRT and N-CoR through an unusual mode involving multiple contact surfaces; the corepressor N-terminus contacts the receptor DNA binding domain (rather than the hormone binding domain), and this interaction is modulated by ER recognition of cognate DNA binding sites; several other nuclear receptors and N-CoR share this novel mode of corepressor recruitment.

2011 Muscle-specific loss of NCoR1 in mice leads to enhanced exercise endurance due to increased muscle mass and mitochondrial number and activity, mediated by activation of transcription factors MEF2, PPARβ/δ, and ERRs; NCoR1 levels are decreased in conditions requiring fat oxidation; knockdown of gei-8 (the sole C. elegans NCoR1 homolog) also increases muscle mitochondria and respiration.
