| molecular function |
|---|
| | GO:0005525 | | GTP binding | | Interacting selectively and non-covalently with GTP, guanosine triphosphate. |
| | GO:0003924 | | GTPase activity | | Catalysis of the reaction: GTP + H2O = GDP + phosphate. |
| | GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| | 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). |
| biological process |
|---|
| | GO:0006897 | | endocytosis | | A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a small region of the plasma membrane to form a new membrane-bounded vesicle. |
| | GO:0016236 | | macroautophagy | | The major inducible pathway for the general turnover of cytoplasmic constituents in eukaryotic cells, it is also responsible for the degradation of active cytoplasmic enzymes and organelles during nutrient starvation. Macroautophagy involves the formation of double-membrane-bounded autophagosomes which enclose the cytoplasmic constituent targeted for degradation in a membrane-bounded structure. Autophagosomes then fuse with a lysosome (or vacuole) releasing single-membrane-bounded autophagic bodies that are then degraded within the lysosome (or vacuole). Though once thought to be a purely non-selective process, it appears that some types of macroautophagy, e.g. macropexophagy, macromitophagy, may involve selective targeting of the targets to be degraded. |
| | GO:0090385 | | phagosome-lysosome fusion | | The creation of a phagolysosome from a phagosome and a lysosome. |
| | GO:0034727 | | piecemeal microautophagy of nucleus | | Degradation of a cell nucleus by lysosomal microautophagy. |
| | GO:0032258 | | protein localization by the CVT pathway | | A cytoplasm to vacuole targeting pathway that uses machinery common with autophagy. The CVT vesicle is formed when the receptor protein, Atg19, binds to the complexes of the target protein (aminopeptidase or alpha-mannosidase homododecamers), forming the Cvt complex. Atg11 binds to Atg9 and transports the CVT complex to the pre-autophagosome (PAS). The phagophore membrane expands around the CVT complex (excluding bulk cytoplasm) forming the CVT vesicle. This pathway is mostly observed in yeast. |
| | GO:0072665 | | protein localization to vacuole | | A process in which a protein is transported to, or maintained at, a location in a vacuole. |
| | 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:0032889 | | regulation of vacuole fusion, non-autophagic | | Any process that modulates the frequency, rate or extent of the fusion of two vacuole membranes to form a single vacuole. |
| | GO:0042147 | | retrograde transport, endosome to Golgi | | The directed movement of membrane-bounded vesicles from endosomes back to the trans-Golgi network where they are recycled for further rounds of transport. |
| | GO:0007264 | | small GTPase mediated signal transduction | | Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals. |
| | 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:0000011 | | vacuole inheritance | | The distribution of vacuoles into daughter cells after mitosis or meiosis, mediated by interactions between vacuoles and the cytoskeleton. |
| | 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:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| | GO:0000324 | | fungal-type vacuole | | A vacuole that has both lytic and storage functions. The fungal vacuole is a large, membrane-bounded organelle that functions as a reservoir for the storage of small molecules (including polyphosphate, amino acids, several divalent cations (e.g. calcium), other ions, and other small molecules) as well as being the primary compartment for degradation. It is an acidic compartment, containing an ensemble of acid hydrolases. At least in S. cerevisiae, there are indications that the morphology of the vacuole is variable and correlated with the cell cycle, with logarithmically growing cells having a multilobed, reticulated vacuole, while stationary phase cells contain a single large structure. |
| | GO:0000329 | | fungal-type vacuole membrane | | The lipid bilayer surrounding a vacuole, the shape of which correlates with cell cycle phase. The membrane separates its contents from the cytoplasm of the cell. An example of this structure is found in Saccharomyces cerevisiae. |
| | GO:0005770 | | late endosome | | A prelysosomal endocytic organelle differentiated from early endosomes by lower lumenal pH and different protein composition. Late endosomes are more spherical than early endosomes and are mostly juxtanuclear, being concentrated near the microtubule organizing center. |
| | GO:0005764 | | lysosome | | A small lytic vacuole that has cell cycle-independent morphology and is found in most animal cells and that contains a variety of hydrolases, most of which have their maximal activities in the pH range 5-6. The contained enzymes display latency if properly isolated. About 40 different lysosomal hydrolases are known and lysosomes have a great variety of morphologies and functions. |
| | GO:0045335 | | phagocytic vesicle | | A membrane-bounded intracellular vesicle that arises from the ingestion of particulate material by phagocytosis. |
| | GO:0030906 | | retromer, cargo-selective complex | | The trimeric subcomplex of the retromer, believed to be closely associated with the membrane. This trimeric complex is responsible for recognizing and binding to cargo molecules. The complex comprises three Vps proteins in both yeast and mammalian cells: Vps35p, Vps29p, and Vps26p in yeast, and VPS35, VPS29 and VPS26A or VPS26B in mammals. |
| | GO:0005773 | | vacuole | | A closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. Cells contain one or several vacuoles, that may have different functions from each other. Vacuoles have a diverse array of functions. They can act as a storage organelle for nutrients or waste products, as a degradative compartment, as a cost-effective way of increasing cell size, and as a homeostatic regulator controlling both turgor pressure and pH of the cytosol. |
| | GO:1990816 | | vacuole-mitochondrion membrane contact site | | A zone of apposition between the vacuolar membrane and the mitochondrial outer membrane, important for transfer of lipids between the two organelles. |
