Summaries for NCOR2 Gene

Entrez Gene Summary for NCOR2 Gene

  • This gene encodes a nuclear receptor co-repressor that mediates transcriptional silencing of certain target genes. The encoded protein is a member of a family of thyroid hormone- and retinoic acid receptor-associated co-repressors. This protein acts as part of a multisubunit complex which includes histone deacetylases to modify chromatin structure that prevents basal transcriptional activity of target genes. Aberrant expression of this gene is associated with certain cancers. Alternate splicing results in multiple transcript variants encoding different isoforms.[provided by RefSeq, Apr 2011]

GeneCards Summary for NCOR2 Gene

NCOR2 (Nuclear Receptor Corepressor 2) is a Protein Coding gene. Diseases associated with NCOR2 include thyroid hormone resistance. Among its related pathways are Signaling by GPCR and Disease. GO annotations related to this gene include chromatin binding and protein N-terminus binding. An important paralog of this gene is NCOR1.

UniProtKB/Swiss-Prot for NCOR2 Gene

  • Transcriptional corepressor. Mediates the transcriptional repression activity of some nuclear receptors by promoting chromatin condensation, thus preventing access of the basal transcription. Isoform 1 and isoform 5 have different affinities for different nuclear receptors. Involved in the regulation BCL6-dependent of the germinal center (GC) reactions, mainly through the control of the GC B-cells proliferation and survival.

    Molecular mass:

    Quaternary structure:
    • 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, and may stabilize their interaction with TFIIB. Interacts directly with RARA in the absence of ligand; the interaction represses RARA activity. Interacts (isoform SMRT) with HDAC10. Interacts with MINT. Component of the N-Cor repressor complex, at least composed of NCOR1, NCOR2, HDAC3, TBL1X, TBL1R, CORO2A and GPS2. Interacts with CBFA2T3 and ATXN1L. Interacts with RARB; the interaction is weak and does not repress RARB transactivational activity. Interacts with HDAC7 and C1D. Interacts with NR4A2; this interaction increases in the absence of PITX3. Interacts with BCL6 (via the BTB domain), required for BCL6 transcriptional repressor activity on a subset of target genes. Forms ternary complexes with BCOR and BCL6 on target gene promoters but, on enhancer elements, interacts with BCL6 and HDAC3 to repress proximal gene expression. May interact with DEAF1. Interacts with RXRA. Interacts with MECP2 (By similarity).

  • Q9Y618
  • The N-terminal region contains repression functions that are divided into three independent repression domains (RD1, RD2 and RD3). The C-terminal region contains the nuclear receptor-interacting domains that are divided in two separate interaction domains (ID1 and ID2)
  • The two interaction domains (ID) contain a conserved sequence referred to as the CORNR box. This motif is required and sufficient to permit binding to unligated TR and RARS. Sequences flanking the CORNR box determine nuclear hormone receptor specificity
  • Contains 2 SANT domains.
  • Belongs to the N-CoR nuclear receptor corepressors family.
