molecular function |
| GO:0004869 | | cysteine-type endopeptidase inhibitor activity | | Stops, prevents or reduces the activity of a cysteine-type endopeptidase, any enzyme that hydrolyzes peptide bonds in polypeptides by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile. |
| GO:0008201 | | heparin binding | | Interacting selectively and non-covalently with heparin, any member of a group of glycosaminoglycans found mainly as an intracellular component of mast cells and which consist predominantly of alternating alpha-(1->4)-linked D-galactose and N-acetyl-D-glucosamine-6-sulfate residues. |
| GO:0030414 | | peptidase inhibitor activity | | Stops, prevents or reduces the activity of a peptidase, any enzyme that catalyzes the hydrolysis peptide bonds. |
| 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:0008270 | | zinc ion binding | | Interacting selectively and non-covalently with zinc (Zn) ions. |
biological process |
| GO:0007596 | | blood coagulation | | The sequential process in which the multiple coagulation factors of the blood interact, ultimately resulting in the formation of an insoluble fibrin clot; it may be divided into three stages: stage 1, the formation of intrinsic and extrinsic prothrombin converting principle; stage 2, the formation of thrombin; stage 3, the formation of stable fibrin polymers. |
| 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:0007599 | | hemostasis | | The stopping of bleeding (loss of body fluid) or the arrest of the circulation to an organ or part. |
| 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:0030195 | | negative regulation of blood coagulation | | Any process that stops, prevents, or reduces the frequency, rate or extent of blood coagulation. |
| GO:0007162 | | negative regulation of cell adhesion | | Any process that stops, prevents, or reduces the frequency, rate or extent of cell adhesion. |
| 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:0045861 | | negative regulation of proteolysis | | Any process that stops, prevents, or reduces the frequency, rate or extent of the hydrolysis of a peptide bond or bonds within a protein. |
| GO:0002576 | | platelet degranulation | | The regulated exocytosis of secretory granules containing preformed mediators such as histamine and serotonin by a platelet. |
| GO:0043065 | | positive regulation of apoptotic process | | Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process. |
| GO:0007204 | | positive regulation of cytosolic calcium ion concentration | | Any process that increases the concentration of calcium ions in the cytosol. |
| GO:0035815 | | positive regulation of renal sodium excretion | | Any process that increases the amount of sodium excreted in urine over a unit of time. |
| GO:0035810 | | positive regulation of urine volume | | Any process that increases the amount of urine excreted from the body over a unit of time. |
| GO:0050880 | | regulation of blood vessel size | | Any process that modulates the size of blood vessels. |
| GO:0006939 | | smooth muscle contraction | | A process in which force is generated within smooth muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. Smooth muscle differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. |
| GO:0042311 | | vasodilation | | An increase in the internal diameter of blood vessels, especially arterioles or capillaries, due to relaxation of smooth muscle cells that line the vessels, and usually resulting in a decrease in blood pressure. |
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: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: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. |
| GO:0031093 | | platelet alpha granule lumen | | The volume enclosed by the membrane of the platelet alpha granule. |
