| molecular function |
|---|
| | 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:0017075 | | syntaxin-1 binding | | Interacting selectively and non-covalently with the SNAP receptor syntaxin-1. |
| | GO:0030348 | | syntaxin-3 binding | | Interacting selectively and non-covalently with the SNAP receptor syntaxin-3. |
| biological process |
|---|
| | GO:0006887 | | exocytosis | | A process of secretion by a cell that results in the release of intracellular molecules (e.g. hormones, matrix proteins) contained within a membrane-bounded vesicle. Exocytosis can occur either by full fusion, when the vesicle collapses into the plasma membrane, or by a kiss-and-run mechanism that involves the formation of a transient contact, a pore, between a granule (for exemple of chromaffin cells) and the plasma membrane. The latter process most of the time leads to only partial secretion of the granule content. Exocytosis begins with steps that prepare vesicles for fusion with the membrane (tethering and docking) and ends when molecules are secreted from the cell. |
| | GO:0001909 | | leukocyte mediated cytotoxicity | | The directed killing of a target cell by a leukocyte. |
| | GO:0043312 | | neutrophil degranulation | | The regulated exocytosis of secretory granules containing preformed mediators such as proteases, lipases, and inflammatory mediators by a neutrophil. |
| | GO:0015031 | | protein transport | | The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| | GO:0043304 | | regulation of mast cell degranulation | | Any process that modulates the frequency, rate, or extent of mast cell degranulation. |
| | GO:0006810 | | transport | | The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein. |
| | GO:0006904 | | vesicle docking involved in exocytosis | | The initial attachment of a vesicle membrane to a target membrane, mediated by proteins protruding from the membrane of the vesicle and the target membrane, that contributes to exocytosis. |
| | GO:0016192 | | vesicle-mediated transport | | A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane. |
| cellular component |
|---|
| | GO:0031201 | | SNARE complex | | A protein complex involved in membrane fusion; a stable ternary complex consisting of a four-helix bundle, usually formed from one R-SNARE and three Q-SNAREs with an ionic layer sandwiched between hydrophobic layers. One well-characterized example is the neuronal SNARE complex formed of synaptobrevin 2, syntaxin 1a, and SNAP-25. |
| | GO:0016324 | | apical plasma membrane | | The region of the plasma membrane located at the apical end of the cell. |
| | GO:0042582 | | azurophil granule | | Primary lysosomal granule found in neutrophil granulocytes. Contains a wide range of hydrolytic enzymes and is released into the extracellular fluid. |
| | GO:0044194 | | cytolytic granule | | A specialized secretory lysosome that is present in cells with cytolytic capability such as cytotoxic T lymphocytes and natural killer cells. Cytolytic granules mediate the storage and regulated excretion of lytic molecules for killing of target cells. |
| | 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: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:0042581 | | specific granule | | Granule with a membranous, tubular internal structure, found primarily in mature neutrophil cells. Most are released into the extracellular fluid. Specific granules contain lactoferrin, lysozyme, vitamin B12 binding protein and elastase. |
| | GO:0070820 | | tertiary granule | | A secretory granule that contains cathepsin and gelatinase and is readily exocytosed upon cell activation; found primarily in mature neutrophil cells. |
