NMR Structure(hide GO term definitions)
Chain A   (NCOR2_HUMAN | Q9Y618)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0005112    Notch binding    Interacting selectively and non-covalently with the Notch (N) protein, a surface receptor.
    GO:0042826    histone deacetylase binding    Interacting selectively and non-covalently with the enzyme histone deacetylase.
    GO:0016922    ligand-dependent nuclear receptor binding    Interacting selectively and non-covalently, in a ligand dependent manner, with a nuclear receptor protein.
    GO:0047485    protein N-terminus binding    Interacting selectively and non-covalently with a protein N-terminus, the end of any peptide chain at which the 2-amino (or 2-imino) function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0003714    transcription corepressor activity    Interacting selectively and non-covalently with a repressing transcription factor and also with the basal transcription machinery in order to stop, prevent, or reduce the frequency, rate or extent of transcription. Cofactors generally do not bind the template nucleic acid, but rather mediate protein-protein interactions between repressive transcription factors and the basal transcription machinery.
    GO:0008134    transcription factor binding    Interacting selectively and non-covalently with a transcription factor, any protein required to initiate or regulate transcription.
biological process
    GO:0044255    cellular lipid metabolic process    The chemical reactions and pathways involving lipids, as carried out by individual cells.
    GO:1903799    negative regulation of production of miRNAs involved in gene silencing by miRNA    Any process that stops, prevents or reduces the frequency, rate or extent of production of miRNAs involved in gene silencing by miRNA.
    GO:0000122    negative regulation of transcription from RNA polymerase II promoter    Any process that stops, prevents, or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0072365    regulation of cellular ketone metabolic process by negative regulation of transcription from RNA polymerase II promoter    Any process that modulates the frequency, rate or extent of a cellular ketone metabolic process by stopping, preventing, or reducing the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0000118    histone deacetylase complex    A protein complex that possesses histone deacetylase activity.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0016604    nuclear body    Extra-nucleolar nuclear domains usually visualized by confocal microscopy and fluorescent antibodies to specific proteins.
    GO:0000790    nuclear chromatin    The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome in the nucleus.
    GO:0016363    nuclear matrix    The dense fibrillar network lying on the inner side of the nuclear membrane.
    GO:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
    GO:0017053    transcriptional repressor complex    A protein complex that possesses activity that prevents or downregulates transcription.
