molecular function |
| GO:0017049 | | GTP-Rho binding | | Interacting selectively and non-covalently with the GTP-bound form of the Rho protein. |
| GO:0005546 | | phosphatidylinositol-4,5-bisphosphate binding | | Interacting selectively and non-covalently with phosphatidylinositol-4,5-bisphosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 4' and 5' positions. |
| 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:0006893 | | Golgi to plasma membrane transport | | The directed movement of substances from the Golgi to the plasma membrane in transport vesicles that move from the trans-Golgi network to the plasma membrane, where they fuse and release their contents by exocytosis. |
| GO:0007266 | | Rho protein signal transduction | | A series of molecular signals within the cell that are mediated by a member of the Rho family of proteins switching to a GTP-bound active state. |
| GO:0001927 | | exocyst assembly | | The aggregation, arrangement and bonding together of various polypeptides into the exocyst complex. |
| GO:0051601 | | exocyst localization | | Any process in which an exocyst is transported to, or maintained in, a specific location. An exocyst is a protein complex peripherally associated with the plasma membrane that determines where vesicles dock and fuse. |
| 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: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: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:0090522 | | vesicle tethering involved in exocytosis | | The initial, indirect interaction between a secretory vesicle membrane and a site of exocytosis in the plasma membrane. This interaction is mediated by tethering factors (or complexes), which interact with both membranes. Interaction can occur via direct binding to membrane phospholipids or membrane proteins, or via binding to vesicle coat proteins. This process is distinct from and prior to docking and fusion. |
cellular component |
| GO:0005933 | | cellular bud | | A protuberance from a cell of an organism that reproduces by budding, which will grow larger and become a separate daughter cell after nuclear division, cytokinesis, and cell wall formation (when appropriate). The daughter cell may completely separate from the mother cell, or the mother and daughter cells may remain associated. |
| GO:0005935 | | cellular bud neck | | The constriction between the mother cell and daughter cell (bud) in an organism that reproduces by budding. |
| GO:0005934 | | cellular bud tip | | The end of a cellular bud distal to the site of attachment to the mother cell. |
| GO:0031410 | | cytoplasmic vesicle | | A vesicle found in the cytoplasm of a cell. |
| GO:0000145 | | exocyst | | A protein complex peripherally associated with the plasma membrane that determines where vesicles dock and fuse. At least eight complex components are conserved between yeast and mammals. |
| GO:0000131 | | incipient cellular bud site | | The portion of the budding yeast plasma membrane where a daughter cell will emerge. The yeast marks this spot with bud-site selection proteins before bud emergence occurs. Actin is polarized to this spot just prior to and during bud emergence. |
| 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:0030133 | | transport vesicle | | Any of the vesicles of the constitutive secretory pathway, which carry cargo from the endoplasmic reticulum to the Golgi, between Golgi cisternae, from the Golgi to the ER (retrograde transport) or to destinations within or outside the cell. |
