Human Gene NCOR1 (uc002gpo.3) Description and Page Index
  Description: Homo sapiens nuclear receptor corepressor 1 (NCOR1), transcript variant 1, mRNA.
RefSeq Summary (NM_006311): This gene encodes a protein that mediates ligand-independent transcription repression of thyroid-hormone and retinoic-acid receptors by promoting chromatin condensation and preventing access of the transcription machinery. It is part of a complex which also includes histone deacetylases and transcriptional regulators similar to the yeast protein Sin3p. This gene is located between the Charcot-Marie-Tooth and Smith-Magenis syndrome critical regions on chromosome 17. Alternate splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 17 and 20.[provided by RefSeq, Jun 2010].

DESCRIPTION: RecName: Full=Nuclear receptor corepressor 1; Short=N-CoR; Short=N-CoR1;
FUNCTION: Mediates transcriptional repression by certain nuclear receptors. Part of a complex which promotes histone deacetylation and the formation of repressive chromatin structures which may impede the access of basal transcription factors.
SUBUNIT: Interacts with C1D, SIAH2, HDAC7, SAP30, SIN3A and SIN3B (By similarity). Forms a large corepressor complex that contains. SIN3A/B and histone deacetylases HDAC1 and HDAC2. This complex associates with the thyroid (TR) and the retinoid acid receptors (RAR) in the absence of ligand. Interacts directly with RARA; the interaction is faciliated with RARA trimethylation. Interacts with DACH1. Component of the N-Cor repressor complex, at least composed of NCOR1, NCOR2, HDAC3, TBL1X, TBL1XR1, CORO2A and GPS2. Interacts with TRIM28 and KDM3A. Interacts with ZBTB33; the interaction serves to recruit the N-CoR complex to promoter regions containing methylated CpG dinucleotides. Interacts with HDAC9 (via its catalytic domain). Interacts with CBFA2T3 and HEXIM1. Interacts (via the RRFD1 domain) with BAZ1A (via its N-terminal); the interaction corepresses a number of NCOR1-regulated genes.
INTERACTION: Q9UI36:DACH1; NbExp=2; IntAct=EBI-347233, EBI-347111; O15379:HDAC3; NbExp=2; IntAct=EBI-347233, EBI-607682; P10276:RARA; NbExp=3; IntAct=EBI-347233, EBI-413374; Q13263:TRIM28; NbExp=4; IntAct=EBI-347233, EBI-78139;
SUBCELLULAR LOCATION: Nucleus (By similarity).
DOMAIN: The N-terminal region contains three independent domains that are capable of mediating transcriptional repression (RD1, RD2 and RD3).
DOMAIN: The C-terminal region contains two separate nuclear receptor-interacting domains (ID1 and ID2), each of which contains a conserved sequence referred to as the CORNR box. This motif is necessary and sufficient for binding to unligated nuclear hormone receptors, while sequences flanking the CORNR box determine the precise nuclear hormone receptor specificity (By similarity).
PTM: Ubiquitinated; mediated by SIAH2 and leading to its subsequent proteasomal degradation (By similarity).
SIMILARITY: Belongs to the N-CoR nuclear receptor corepressors family.
SIMILARITY: Contains 2 SANT domains.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
