NMR Structure(hide GO term definitions)
Chain A   (CMGA_BOVIN | P05059)
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:0050829    defense response to Gram-negative bacterium    Reactions triggered in response to the presence of a Gram-negative bacterium that act to protect the cell or organism.
    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:0045087    innate immune response    Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
    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:0045576    mast cell activation    The change in morphology and behavior of a mast cell resulting from exposure to a cytokine, chemokine, soluble factor, or to (at least in mammals) an antigen which the mast cell has specifically bound via IgE bound to Fc-epsilonRI receptors.
    GO:0002551    mast cell chemotaxis    The movement of a mast cell in response to an external stimulus.
    GO:0032762    mast cell cytokine production    Any process that contributes to cytokine production by a mast cell.
    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.
    GO:0016525    negative regulation of angiogenesis    Any process that stops, prevents, or reduces the frequency, rate or extent of angiogenesis.
    GO:0033604    negative regulation of catecholamine secretion    Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of a catecholamine.
    GO:0046888    negative regulation of hormone secretion    Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of a hormone from a cell.
    GO:0046676    negative regulation of insulin secretion    Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of insulin.
    GO:2000707    positive regulation of dense core granule biogenesis    Any process that activates or increases the frequency, rate or extent of dense core granule biogenesis.
    GO:0030155    regulation of cell adhesion    Any process that modulates the frequency, rate or extent of attachment of a cell to another cell or to the extracellular matrix.
cellular component
    GO:0031410    cytoplasmic vesicle    A vesicle found in the cytoplasm of a cell.
    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.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0030141    secretory granule    A small subcellular vesicle, surrounded by a membrane, that is formed from the Golgi apparatus and contains a highly concentrated protein destined for secretion. Secretory granules move towards the periphery of the cell and upon stimulation, their membranes fuse with the cell membrane, and their protein load is exteriorized. Processing of the contained protein may take place in secretory granules.
    GO:0030133    transport vesicle    Any of the vesicles of the constitutive secretory pathway, which carry cargo from the endoplasmic reticulum to the Golgi, between Golgi cisternae, from the Golgi to the ER (retrograde transport) or to destinations within or outside the cell.
    GO:0030658    transport vesicle membrane    The lipid bilayer surrounding a transport vesicle.
