Chain A   (A2MG_HUMAN | P01023)
molecular function
    GO:0005096    GTPase activator activity    Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
    GO:0048306    calcium-dependent 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), in the presence of calcium.
    GO:0004866    endopeptidase inhibitor activity    Stops, prevents or reduces the activity of an endopeptidase, any enzyme that hydrolyzes nonterminal peptide bonds in polypeptides.
    GO:0019899    enzyme binding    Interacting selectively and non-covalently with any enzyme.
    GO:0019838    growth factor binding    Interacting selectively and non-covalently with any growth factor, proteins or polypeptides that stimulate a cell or organism to grow or proliferate.
    GO:0019966    interleukin-1 binding    Interacting selectively and non-covalently with interleukin-1.
    GO:0019959    interleukin-8 binding    Interacting selectively and non-covalently with interleukin-8.
    GO:0030414    peptidase inhibitor activity    Stops, prevents or reduces the activity of a peptidase, any enzyme that catalyzes the hydrolysis peptide bonds.
    GO:0002020    protease binding    Interacting selectively and non-covalently with any protease or peptidase.
    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).
    GO:0005102    receptor binding    Interacting selectively and non-covalently with one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.
    GO:0004867    serine-type endopeptidase inhibitor activity    Stops, prevents or reduces the activity of serine-type endopeptidases, enzymes that catalyze the hydrolysis of nonterminal peptide bonds in a polypeptide chain; a serine residue (and a histidine residue) are at the active center of the enzyme.
    GO:0043120    tumor necrosis factor binding    Interacting selectively and non-covalently with tumor necrosis factor, a proinflammatory cytokine produced by monocytes and macrophages.
biological process
    GO:0007597    blood coagulation, intrinsic pathway    A protein activation cascade that contributes to blood coagulation and consists of the interactions among high molecular weight kininogen, prekallikrein, and factor XII that lead to the activation of clotting factor X.
    GO:0022617    extracellular matrix disassembly    A process that results in the breakdown of the extracellular matrix.
    GO:0001869    negative regulation of complement activation, lectin pathway    Any process that stops, prevents, or reduces the rate of complement activation by the lectin pathway.
    GO:0010951    negative regulation of endopeptidase activity    Any process that decreases the frequency, rate or extent of endopeptidase activity, the endohydrolysis of peptide bonds within proteins.
    GO:0010466    negative regulation of peptidase activity    Any process that stops or reduces the rate of peptidase activity, the hydrolysis of peptide bonds within proteins.
    GO:0002576    platelet degranulation    The regulated exocytosis of secretory granules containing preformed mediators such as histamine and serotonin by a platelet.
    GO:0043547    positive regulation of GTPase activity    Any process that activates or increases the activity of a GTPase.
    GO:0051056    regulation of small GTPase mediated signal transduction    Any process that modulates the frequency, rate or extent of small GTPase mediated signal transduction.
    GO:0048863    stem cell differentiation    The process in which a relatively unspecialized cell acquires specialized features of a stem cell. A stem cell is a cell that retains the ability to divide and proliferate throughout life to provide progenitor cells that can differentiate into specialized cells.
cellular component
    GO:0072562    blood microparticle    A phospholipid microvesicle that is derived from any of several cell types, such as platelets, blood cells, endothelial cells, or others, and contains membrane receptors as well as other proteins characteristic of the parental cell. Microparticles are heterogeneous in size, and are characterized as microvesicles free of nucleic acids.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    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.
    GO:0031093    platelet alpha granule lumen    The volume enclosed by the membrane of the platelet alpha granule.
