NMR Structure(hide GO term definitions)
Chain A   (PLR_LITPI | Q90WP7)
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:0019835    cytolysis    The rupture of cell membranes and the loss of cytoplasm.
    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:0044179    hemolysis in other organism    The cytolytic destruction of red blood cells, with the release of intracellular hemoglobin, in one organism by another.
    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: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.
    GO:0043303    mast cell degranulation    The regulated exocytosis of secretory granules containing preformed mediators such as histamine, serotonin, and neutral proteases by a mast 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:0042629    mast cell granule    Coarse, bluish-black staining cytoplasmic granules, bounded by a plasma membrane and found in mast cells and basophils. Contents include histamine, heparin, chondroitin sulfates, chymase and tryptase.
