Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (PD1L1_HUMAN | Q9NZQ7)
molecular function
    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:0031295    T cell costimulation    The process of providing, via surface-bound receptor-ligand pairs, a second, antigen-independent, signal in addition to that provided by the T cell receptor to augment T cell activation.
    GO:0007166    cell surface receptor signaling pathway    A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription.
    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:0042130    negative regulation of T cell proliferation    Any process that stops, prevents or reduces the rate or extent of T cell proliferation.
    GO:0046007    negative regulation of activated T cell proliferation    Any process that stops, prevents or reduces the rate or extent of activated T cell proliferation.
    GO:0032689    negative regulation of interferon-gamma production    Any process that stops, prevents, or reduces the frequency, rate, or extent of interferon-gamma production. Interferon-gamma is also known as type II interferon.
    GO:0032693    negative regulation of interleukin-10 production    Any process that stops, prevents, or reduces the frequency, rate, or extent of interleukin-10 production.
    GO:1903556    negative regulation of tumor necrosis factor superfamily cytokine production    Any process that stops, prevents or reduces the frequency, rate or extent of tumor necrosis factor superfamily cytokine production.
    GO:0042102    positive regulation of T cell proliferation    Any process that activates or increases the rate or extent of T cell proliferation.
    GO:0030335    positive regulation of cell migration    Any process that activates or increases the frequency, rate or extent of cell migration.
    GO:2001181    positive regulation of interleukin-10 secretion    Any process that activates or increases the frequency, rate or extent of interleukin-10 secretion.
    GO:0070232    regulation of T cell apoptotic process    Any process that modulates the occurrence or rate of T cell death by apoptotic process.
    GO:0046006    regulation of activated T cell proliferation    Any process that modulates the frequency, rate or extent of activated T cell proliferation.
    GO:0034097    response to cytokine    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 cytokine stimulus.
    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.
    GO:1901998    toxin transport    The directed movement of a toxin into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
cellular component
    GO:0009986    cell surface    The external part of the cell wall and/or plasma membrane.
    GO:0012505    endomembrane system    A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles.
    GO:0009897    external side of plasma membrane    The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.
    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:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    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.
