NMR Structure(hide GO term definitions)
Chain A   (MED25_HUMAN | Q71SY5)
molecular function
    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:0042974    retinoic acid receptor binding    Interacting selectively and non-covalently with the retinoic acid receptor, a ligand-regulated transcription factor belonging to the nuclear receptor superfamily.
    GO:0046965    retinoid X receptor binding    Interacting selectively and non-covalently with a retinoid X receptor.
    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:0048147    negative regulation of fibroblast proliferation    Any process that stops, prevents, or reduces the frequency, rate or extent of multiplication or reproduction of fibroblast cells.
    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:0071158    positive regulation of cell cycle arrest    Any process that increases the rate, frequency, or extent of cell cycle arrest, the process in which the cell cycle is halted during one of the normal phases.
    GO:0035563    positive regulation of chromatin binding    Any process that increases the frequency, rate or extent of chromatin binding. Chromatin binding is the selective interaction with chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase.
    GO:2001178    positive regulation of mediator complex assembly    Any process that activates or increases the frequency, rate or extent of mediator complex assembly.
    GO:0045944    positive regulation of transcription from RNA polymerase II promoter    Any process that activates or increases 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:0006367    transcription initiation from RNA polymerase II promoter    Any process involved in the assembly of the RNA polymerase II preinitiation complex (PIC) at an RNA polymerase II promoter region of a DNA template, resulting in the subsequent synthesis of RNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. Promoter clearance, or release, is the transition between the initiation and elongation phases of transcription.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0044798    nuclear transcription factor complex    A protein complex, located in the nucleus, that is capable of associating with DNA by direct binding, or via other DNA-binding proteins or complexes, and regulating transcription.
    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.
