| GO:0005774 | vacuolar membrane | The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell. | 2582 |
| GO:0009705 | plant-type vacuole membrane | The lipid bilayer surrounding a vacuole that retains the same shape regardless of cell cycle phase. The membrane separates its contents from the cytoplasm of the cell. An example of this component is found in Arabidopsis thaliana. | 589 |
| 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. | 334 |
| 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. | 309 |
| GO:0000325 | plant-type vacuole | A closed structure that is completely surrounded by a unit membrane, contains liquid, and retains the same shape regardless of cell cycle phase. An example of this structure is found in Arabidopsis thaliana. | 218 |
| GO:0000331 | contractile vacuole | A specialized vacuole of eukaryotic cells, especially Protozoa, that fills with water from the cytoplasm and then discharges this externally by the opening of contractile vacuole pores. Its function is probably osmoregulatory. | 116 |
| 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. | 92 |
| GO:0000326 | protein storage vacuole | A storage vacuole that contains a lytic vacuole; identified in plants. | 79 |
| GO:0042807 | central vacuole | A membrane-enclosed sac that takes up most of the volume of a mature plant cell. Functions include storage, separation of toxic byproducts, and cell growth determination. | 53 |
| GO:0005775 | vacuolar lumen | The volume enclosed within the vacuolar membrane. | 38 |
| GO:0000323 | lytic vacuole | A vacuole that is maintained at an acidic pH and which contains degradative enzymes, including a wide variety of acid hydrolases. | 36 |
| GO:0010282 | senescence-associated vacuole | A lytic vacuole that is maintained at acidic pH and has different tonoplast composition compared to the central vacuole. Found during leaf senescence and develops in the peripheral cytoplasm of cells that contain chloroplast. | 30 |
| GO:0000221 | vacuolar proton-transporting V-type ATPase, V1 domain | The V1 domain of a proton-transporting V-type ATPase found in the vacuolar membrane. | 28 |
| GO:0000421 | autophagic vacuole membrane | The lipid bilayer surrounding an autophagic vacuole, a double-membrane-bounded vesicle in which endogenous cellular material is sequestered. | 22 |
| GO:0000220 | vacuolar proton-transporting V-type ATPase, V0 domain | The V0 domain of a proton-transporting V-type ATPase found in the vacuolar membrane. | 20 |
| GO:0005776 | autophagic vacuole | A double-membrane-bounded compartment in which endogenous cellular material is sequestered; known as autophagosome in yeast. | 18 |
| GO:0031164 | contractile vacuolar membrane | The lipid bilayer surrounding the contractile vacuole. | 15 |
| GO:0000328 | fungal-type vacuole lumen | The volume enclosed within the vacuolar membrane of a vacuole, the shape of which correlates with cell cycle phase. An example of this structure is found in Saccharomyces cerevisiae. | 14 |
| GO:0044753 | amphisome | An autophagic vacuole formed upon fusion between autophagosomes and endosomes. | 12 |
| GO:0000306 | extrinsic to vacuolar membrane | Loosely bound to one or the other surface of the vacuolar membrane, but not integrated into the hydrophobic region. | 8 |
| GO:0030897 | HOPS complex | A multimeric protein complex that associates with the vacuolar membrane and is involved in homotypic vacuole fusion and vacuole protein sorting. For example, the Saccharomyces complex contains Vps41p, Vam6p, Pep5p, Vps16p, Pep3p, and Vps33p. | 8 |
| GO:0000327 | lytic vacuole within protein storage vacuole | A membrane-bounded compartment containing crystals of phytic acid and proteins characteristic of a lytic vacuole, found within a storage vacuole. | 7 |
| GO:0043159 | acrosomal matrix | A structural framework, or 'dense core' at the interior of an acrosome. May regulate the distribution of hydrolases within the acrosome and their release during the acrosome reaction. | 5 |
| GO:0032195 | post-lysosomal vacuole | A membrane-bounded intracellular vesicle formed late in the endocytic pathway when the pH in the vacuole becomes neutral prior to exocytosis. | 4 |
| GO:0044437 | vacuolar part | Any constituent part of a vacuole, a closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. | 3 |
| GO:0071627 | integral to fungal-type vacuolar membrane | Located such that some or all of the gene product itself penetrates at least one phospholipid bilayer of the fungal-type vacuolar membrane. May also refer to the state of being buried in the bilayer with no exposure outside the bilayer. | 3 |
| GO:0070772 | PAS complex | A protein complex that contains a phosphatidylinositol-3-phosphate 5-kinase subunit (Fab1p in yeast; PIKfyve in mammals), a kinase activator, and a phosphatase, and may also contain additional proteins; it is involved in regulating the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate. In mammals the complex is composed of PIKFYVE, FIG4 and VAC14. In yeast it is composed of Atg18p, Fig4p, Fab1p, Vac14p and Vac7p. | 2 |
