Theoretical Model(hide GO term definitions)
Chain A   (IL1RA_HUMAN | P18510)
molecular function
    GO:0005125    cytokine activity    Functions to control the survival, growth, differentiation and effector function of tissues and cells.
    GO:0045352    interleukin-1 Type I receptor antagonist activity    Blocks the binding of interleukin-1 to interleukin-1 Type I receptors.
    GO:0045353    interleukin-1 Type II receptor antagonist activity    Blocks the binding of interleukin-1 to interleukin-1 Type II receptors.
    GO:0005152    interleukin-1 receptor antagonist activity    Blocks the binding of interleukin-1 to the interleukin-1 receptor complex.
    GO:0005149    interleukin-1 receptor binding    Interacting selectively and non-covalently with the interleukin-1 receptor.
    GO:0005150    interleukin-1, Type I receptor binding    Interacting selectively and non-covalently with a Type I interleukin-1 receptor.
    GO:0005151    interleukin-1, Type II receptor binding    Interacting selectively and non-covalently with a Type II interleukin-1 receptor.
    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:0006953    acute-phase response    An acute inflammatory response that involves non-antibody proteins whose concentrations in the plasma increase in response to infection or injury of homeothermic animals.
    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:0030073    insulin secretion    The regulated release of proinsulin from secretory granules (B granules) in the B cells of the pancreas; accompanied by cleavage of proinsulin to form mature insulin.
    GO:0006629    lipid metabolic process    The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids.
    GO:0001960    negative regulation of cytokine-mediated signaling pathway    Any process that stops, prevents, or reduces the frequency, rate or extent of the cytokine mediated signaling pathway.
    GO:0034115    negative regulation of heterotypic cell-cell adhesion    Any process that stops, prevents, or reduces the frequency, rate, or extent of heterotypic cell-cell adhesion.
    GO:2000660    negative regulation of interleukin-1-mediated signaling pathway    Any process that stops, prevents or reduces the frequency, rate or extent of interleukin-1-mediated signaling pathway.
    GO:0051384    response to glucocorticoid    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a glucocorticoid stimulus. Glucocorticoids are hormonal C21 corticosteroids synthesized from cholesterol with the ability to bind with the cortisol receptor and trigger similar effects. Glucocorticoids act primarily on carbohydrate and protein metabolism, and have anti-inflammatory effects.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    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.
    GO:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
    GO:0031982    vesicle    Any small, fluid-filled, spherical organelle enclosed by membrane.
