Chain A,B,C,D   (PAI1_HUMAN | P05121)
molecular function
    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.
biological process
    GO:0001525    angiogenesis    Blood vessel formation when new vessels emerge from the proliferation of pre-existing blood vessels.
    GO:0071222    cellular response to lipopolysaccharide    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lipopolysaccharide stimulus; lipopolysaccharide is a major component of the cell wall of gram-negative bacteria.
    GO:0001300    chronological cell aging    The process associated with progression of the cell from its inception to the end of its lifespan that occurs when the cell is in a non-dividing, or quiescent, state.
    GO:0007623    circadian rhythm    Any biological process in an organism that recurs with a regularity of approximately 24 hours.
    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:0030198    extracellular matrix organization    A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.
    GO:0042730    fibrinolysis    A process that solubilizes fibrin in the bloodstream of a multicellular organism, chiefly by the proteolytic action of plasmin.

    GO:0061044    negative regulation of vascular wound healing    Any process that decreases the rate, frequency, or extent of blood vessel formation when new vessels emerge from the proliferation of pre-existing blood vessels and contribute to the series of events that restore integrity to damaged vasculature.
    GO:0061045    negative regulation of wound healing    Any process that decreases the rate, frequency, or extent of the series of events that restore integrity to a damaged tissue, following an injury.
    GO:0002576    platelet degranulation    The regulated exocytosis of secretory granules containing preformed mediators such as histamine and serotonin by a platelet.
    GO:0045766    positive regulation of angiogenesis    Any process that activates or increases angiogenesis.
    GO:0030194    positive regulation of blood coagulation    Any process that activates or increases the frequency, rate or extent of blood coagulation.
    GO:0050729    positive regulation of inflammatory response    Any process that activates or increases the frequency, rate or extent of the inflammatory response.
    GO:0032757    positive regulation of interleukin-8 production    Any process that activates or increases the frequency, rate, or extent of interleukin-8 production.
    GO:0035491    positive regulation of leukotriene production involved in inflammatory response    Any process that increases the rate, frequency or extent of the synthesis or release of any leukotriene following a stimulus as part of an inflammatory response.
    GO:0090026    positive regulation of monocyte chemotaxis    Any process that increases the frequency, rate, or extent of monocyte chemotaxis.
    GO:0048260    positive regulation of receptor-mediated endocytosis    Any process that activates or increases the frequency, rate or extent of receptor mediated endocytosis, the uptake of external materials by cells, utilizing receptors to ensure specificity of transport.
    GO:0045944    positive regulation of transcription from RNA polymerase II promoter    Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0010469    regulation of receptor activity    Any process that modulates the frequency, rate or extent of receptor activity. Receptor activity is when a molecule combines with an extracellular or intracellular messenger to initiate a change in cell activity.
cellular component
    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:0031012    extracellular matrix    A structure lying external to one or more cells, which provides structural support for cells or tissues.
    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: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.
