NMR Structure(hide GO term definitions)
Chain A   (IL18_HUMAN | Q14116)
molecular function
    GO:0005125    cytokine activity    Functions to control the survival, growth, differentiation and effector function of tissues and cells.
    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).
biological process
    GO:0000165    MAPK cascade    An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain two additional tiers: the upstream MAP4K and the downstream MAP Kinase-activated kinase (MAPKAPK). The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell.
    GO:0042088    T-helper 1 type immune response    An immune response which is associated with resistance to intracellular bacteria, fungi, and protozoa, and pathological conditions such as arthritis, and which is typically orchestrated by the production of particular cytokines by T-helper 1 cells, most notably interferon-gamma, IL-2, and lymphotoxin.
    GO:0001525    angiogenesis    Blood vessel formation when new vessels emerge from the proliferation of pre-existing blood vessels.
    GO:0007267    cell-cell signaling    Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions.
    GO:0071407    cellular response to organic cyclic compound    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an organic cyclic compound stimulus.
    GO:0042033    chemokine biosynthetic process    The chemical reactions and pathways resulting in the formation of chemokines, any member of a family of small chemotactic cytokines; their name is derived from their ability to induce directed chemotaxis in nearby responsive cells. All chemokines possess a number of conserved cysteine residues involved in intramolecular disulfide bond formation. Some chemokines are considered pro-inflammatory and can be induced during an immune response to recruit cells of the immune system to a site of infection, while others are considered homeostatic and are involved in controlling the migration of cells during normal processes of tissue maintenance or development. Chemokines are found in all vertebrates, some viruses and some bacteria.
    GO:0042253    granulocyte macrophage colony-stimulating factor biosynthetic process    The chemical reactions and pathways resulting in the formation of granulocyte macrophage colony-stimulating factor, cytokines that act in hemopoiesis by controlling the production, differentiation, and function of two related white cell populations, granulocytes and monocytes-macrophages.
    GO:0006955    immune response    Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.
    GO:0006954    inflammatory response    The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages.
    GO:0042095    interferon-gamma biosynthetic process    The chemical reactions and pathways resulting in the formation of interferon-gamma. Interferon gamma is the only member of the type II interferon found so far.
    GO:0042231    interleukin-13 biosynthetic process    The chemical reactions and pathways resulting in the formation of interleukin-13.
    GO:0042094    interleukin-2 biosynthetic process    The chemical reactions and pathways resulting in the formation of interleukin-2.
    GO:0031663    lipopolysaccharide-mediated signaling pathway    A series of molecular signals initiated by the binding of a lipopolysaccharide (LPS) to a receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription. Lipopolysaccharides are major components of the outer membrane of Gram-negative bacteria, making them prime targets for recognition by the immune system.
    GO:0030101    natural killer cell activation    The change in morphology and behavior of a natural killer cell in response to a cytokine, chemokine, cellular ligand, or soluble factor.
    GO:0045662    negative regulation of myoblast differentiation    Any process that stops, prevents, or reduces 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:0042346    positive regulation of NF-kappaB import into nucleus    Any process that activates or increases the frequency, rate or extent of transfer of NF-kappaB, a transcription factor for eukaryotic RNA polymerase II promoters, from the cytoplasm into the nucleus, across the nuclear membrane.
    GO:0051142    positive regulation of NK T cell proliferation    Any process that activates or increases the frequency, rate or extent of natural killer T cell proliferation.
    GO:0042104    positive regulation of activated T cell proliferation    Any process that activates or increases the rate or extent of activated T cell proliferation.
    GO:0010628    positive regulation of gene expression    Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
    GO:0032725    positive regulation of granulocyte macrophage colony-stimulating factor production    Any process that activates or increases the frequency, rate, or extent of granulocyte macrophage colony-stimulating factor production.
    GO:0050729    positive regulation of inflammatory response    Any process that activates or increases the frequency, rate or extent of the inflammatory response.
    GO:0032729    positive regulation of interferon-gamma production    Any process that activates or increases the frequency, rate, or extent of interferon-gamma production. Interferon-gamma is also known as type II interferon.
    GO:0032740    positive regulation of interleukin-17 production    Any process that activates or increases the frequency, rate, or extent of production of any member of the interleukin-17 family of cytokines.
    GO:0032819    positive regulation of natural killer cell proliferation    Any process that activates or increases the frequency, rate or extent of natural killer cell proliferation.
    GO:0034105    positive regulation of tissue remodeling    Any process that activates or increases the frequency, rate, or extent of tissue remodeling.
    GO:0030155    regulation of cell adhesion    Any process that modulates the frequency, rate or extent of attachment of a cell to another cell or to the extracellular matrix.
    GO:0030431    sleep    Any process in which an organism enters and maintains a periodic, readily reversible state of reduced awareness and metabolic activity. Usually accompanied by physical relaxation, the onset of sleep in humans and other mammals is marked by a change in the electrical activity of the brain.
    GO:0042092    type 2 immune response    An immune response which is associated with resistance to extracellular organisms such as helminths and pathological conditions such as allergy, which is orchestrated by the production of particular cytokines, most notably IL-4, IL-5, IL-10, and IL-13, by any of a variety of cell types including T-helper 2 cells, eosinophils, basophils, mast cells, and nuocytes, resulting in enhanced production of certain antibody isotypes and other effects.
cellular component
    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:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
    GO:0005615    extracellular space    That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
