Chain A   (HIF1N_HUMAN | Q9NWT6)
molecular function
    GO:0051059    NF-kappaB binding    Interacting selectively and non-covalently with NF-kappaB, a transcription factor for eukaryotic RNA polymerase II promoters.
    GO:0005112    Notch binding    Interacting selectively and non-covalently with the Notch (N) protein, a surface receptor.
    GO:0071532    ankyrin repeat binding    Interacting selectively and non-covalently with an ankyrin repeat of a protein. Ankyrin repeats are tandemly repeated modules of about 33 amino acids; each repeat folds into a helix-loop-helix structure with a beta-hairpin/loop region projecting out from the helices at a 90-degree angle, and repeats stack to form an L-shaped structure.
    GO:0031406    carboxylic acid binding    Interacting selectively and non-covalently with a carboxylic acid, any organic acid containing one or more carboxyl (COOH) groups or anions (COO-).
    GO:0048037    cofactor binding    Interacting selectively and non-covalently with a cofactor, a substance that is required for the activity of an enzyme or other protein. Cofactors may be inorganic, such as the metal atoms zinc, iron, and copper in certain forms, or organic, in which case they are referred to as coenzymes. Cofactors may either be bound tightly to active sites or bind loosely with the substrate.
    GO:0051213    dioxygenase activity    Catalysis of an oxidation-reduction (redox) reaction in which both atoms of oxygen from one molecule of O2 are incorporated into the (reduced) product(s) of the reaction. The two atoms of oxygen may be distributed between two different products.
    GO:0005506    iron ion binding    Interacting selectively and non-covalently with iron (Fe) ions.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
    GO:0016706    oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, 2-oxoglutarate as one donor, and incorporation of one atom each of oxygen into both donors    Catalysis of the reaction: A + 2-oxoglutarate + O2 = B + succinate + CO2. This is an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from 2-oxoglutarate and one other donor, and one atom of oxygen is incorporated into each donor.
    GO:0019826    oxygen sensor activity    Interacting selectively and non-covalently with and responding, e.g. by conformational change, to changes in the cellular level of oxygen (O2).
    GO:0036140    peptidyl-asparagine 3-dioxygenase activity    Catalysis of the reaction: peptidyl L-asparagine + 2-oxoglutarate + O2 = peptidyl 3-hydroxy-L-asparagine + succinate + CO2.
    GO:0036139    peptidyl-histidine dioxygenase activity    Catalysis of the reaction: peptidyl L-histidine + 2-oxoglutarate + O2 = peptidyl hydroxy-L-histidine + succinate + CO2.
    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:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0045746    negative regulation of Notch signaling pathway    Any process that stops, prevents, or reduces the frequency, rate or extent of the Notch signaling pathway.
    GO:0061428    negative regulation of transcription from RNA polymerase II promoter in response to hypoxia    Any process that decreases the frequency, rate or extent of transcription from an RNA polymerase II promoter as a result of a hypoxia stimulus.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
    GO:0042265    peptidyl-asparagine hydroxylation    The hydroxylation of peptidyl-asparagine to form peptidyl-hydroxyasparagine.
    GO:0042264    peptidyl-aspartic acid hydroxylation    The hydroxylation of peptidyl-aspartic acid to form peptidyl-hydroxyaspartic acid.
    GO:0036138    peptidyl-histidine hydroxylation    The hydroxylation of peptidyl-histidine to form peptidyl-hydroxyhistidine.
    GO:0045663    positive regulation of myoblast differentiation    Any process that activates or increases the frequency, rate or extent of myoblast differentiation. A myoblast is a mononucleate cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into skeletal muscle fibers.
    GO:2001214    positive regulation of vasculogenesis    Any process that activates or increases the frequency, rate or extent of vasculogenesis.
    GO:0061418    regulation of transcription from RNA polymerase II promoter in response to hypoxia    Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter as a result of a hypoxia stimulus.
    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:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    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:0048471    perinuclear region of cytoplasm    Cytoplasm situated near, or occurring around, the nucleus.
