Chain C   (PO2F1_HUMAN | P14859)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0003682    chromatin binding    Interacting selectively and non-covalently with chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase.
    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:0005102    receptor binding    Interacting selectively and non-covalently with one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.
    GO:0043565    sequence-specific DNA binding    Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.
    GO:0003700    transcription factor activity, sequence-specific DNA binding    Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex.
    GO:0000976    transcription regulatory region sequence-specific DNA binding    Interacting selectively and non-covalently with a specific sequence of DNA that is part of a regulatory region that controls transcription of that section of the DNA. The transcribed region might be described as a gene, cistron, or operon.
biological process
    GO:0097421    liver regeneration    The regrowth of lost or destroyed liver.
    GO:0045892    negative regulation of transcription, DNA-templated    Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0042795    snRNA transcription from RNA polymerase II promoter    The synthesis of small nuclear RNA (snRNA) from a DNA template by RNA Polymerase II (Pol II), originating at a Pol II promoter.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0005783    endoplasmic reticulum    The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
    GO:0043231    intracellular membrane-bounded organelle    Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma 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.
