Summaries for NCOR1 Gene

Entrez Gene Summary for NCOR1 Gene

  • 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]

    Molecular mass:
    270210 Da
    Quaternary structure:
    • Forms a large corepressor complex that contains SIN3A/B and histone deacetylases HDAC1 and HDAC2. This complex associates with the thyroid receptor (TR) and the retinoid acid receptor (RAR) in the absence of ligand. Interacts directly with RARA; the interaction is facilitated with RARA trimethylation. Component of the N-Cor repressor complex, at least composed of CBFA2T3, HEXIM1, NCOR1, NCOR2, HDAC3, TBL1X, TBL1XR1, CORO2A and GPS2. Interacts with ZBTB33; the interaction serves to recruit the N-CoR complex to promoter regions containing methylated CpG dinucleotides. Interacts with TRIM28 and KDM3A. Interacts (via the RD1 domain) with BAZ1A (via its N-terminal); the interaction corepresses a number of NCOR1-regulated genes. Interacts with BCL6, C1D, DACH1, HEXIM1, HDAC7, RORA, RORC, SAP30, SIAH2, SIN3A and SIN3B. May interact with DEAF1. Interacts with RXRA. Interacts with SETD5 (By similarity). Interacts with VDR (PubMed:28698609).

  • The N-terminal region contains three independent domains that are capable of mediating transcriptional repression (RD1, RD2 and RD3).
  • Belongs to the N-CoR nuclear receptor corepressors family.
  • The N-terminal region contains three independent domains that are capable of mediating transcriptional repression (RD1, RD2 and RD3).
  • 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).
  • Belongs to the N-CoR nuclear receptor corepressors family.
