Asymmetric Unit(hide GO term definitions)
Chain A,B   (DEF3_HUMAN | P59666)
molecular function
    GO:0003674    molecular_function    Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions.
biological process
    GO:0019731    antibacterial humoral response    An immune response against bacteria mediated through a body fluid. Examples of this process are the antibacterial humoral responses in Mus musculus and Drosophila melanogaster.
    GO:0006952    defense response    Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.
    GO:0050830    defense response to Gram-positive bacterium    Reactions triggered in response to the presence of a Gram-positive bacterium that act to protect the cell or organism.
    GO:0042742    defense response to bacterium    Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.
    GO:0050832    defense response to fungus    Reactions triggered in response to the presence of a fungus that act to protect the cell or organism.
    GO:0051607    defense response to virus    Reactions triggered in response to the presence of a virus that act to protect the cell or organism.
    GO:0045087    innate immune response    Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
    GO:0002227    innate immune response in mucosa    Any process of the innate immune response that takes place in the mucosal tissues.
    GO:0030520    intracellular estrogen receptor signaling pathway    Any series of molecular signals generated as a consequence of an intracellular estrogen receptor binding to one of its physiological ligands. The pathway begins with receptor-ligand binding, and ends with regulation of a downstream cellular process (e.g. transcription).
    GO:0031640    killing of cells of other organism    Any process in an organism that results in the killing of cells of another organism, including in some cases the death of the other organism. Killing here refers to the induction of death in one cell by another cell, not cell-autonomous death due to internal or other environmental conditions.
cellular component
    GO:0005796    Golgi lumen    The volume enclosed by the membranes of any cisterna or subcompartment of the Golgi apparatus, including the cis- and trans-Golgi networks.
    GO:0035578    azurophil granule lumen    The volume enclosed by the membrane of an azurophil granule, a primary lysosomal granule found in neutrophil granulocytes that contains a wide range of hydrolytic enzymes and is released into the extracellular fluid.
    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.
