NMR Structure(hide GO term definitions)
Chain A   (IL21_HUMAN | Q9HBE4)
molecular function
    GO:0005125    cytokine activity    Functions to control the survival, growth, differentiation and effector function of tissues and cells.
    GO:0005126    cytokine receptor binding    Interacting selectively and non-covalently with a cytokine receptor.
    GO:0005134    interleukin-2 receptor binding    Interacting selectively and non-covalently with the interleukin-2 receptor.
biological process
    GO:0048469    cell maturation    A developmental process, independent of morphogenetic (shape) change, that is required for a cell to attain its fully functional state.
    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:0030890    positive regulation of B cell proliferation    Any process that activates or increases the rate or extent of B cell proliferation.
    GO:0042102    positive regulation of T cell proliferation    Any process that activates or increases the rate or extent of T cell proliferation.
    GO:0008284    positive regulation of cell proliferation    Any process that activates or increases the rate or extent of cell proliferation.
    GO:0001819    positive regulation of cytokine production    Any process that activates or increases the frequency, rate or extent of production of a cytokine.
    GO:0050729    positive regulation of inflammatory response    Any process that activates or increases the frequency, rate or extent of the inflammatory response.
    GO:0045078    positive regulation of interferon-gamma biosynthetic process    Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interferon-gamma.
    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:0045954    positive regulation of natural killer cell mediated cytotoxicity    Any process that activates or increases the frequency, rate or extent of natural killer cell mediated cytotoxicity.
    GO:0034105    positive regulation of tissue remodeling    Any process that activates or increases the frequency, rate, or extent of tissue remodeling.
    GO:0007165    signal transduction    The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
cellular component
    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.
