molecular function |
| GO:0005085 | | guanyl-nucleotide exchange factor activity | | Stimulates the exchange of guanyl nucleotides associated with a GTPase. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase. |
| 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:0032947 | | protein complex scaffold activity | | A structural molecule activity that provides a physical support for the assembly of a multiprotein complex. The scaffold may or may not be part of the final complex. |
biological process |
| GO:0000186 | | activation of MAPKK activity | | The initiation of the activity of the inactive enzyme MAP kinase kinase (MAPKK). |
| GO:0016049 | | cell growth | | The process in which a cell irreversibly increases in size over time by accretion and biosynthetic production of matter similar to that already present. |
| GO:0034613 | | cellular protein localization | | Any process in which a protein is transported to, and/or maintained in, a specific location at the level of a cell. Localization at the cellular level encompasses movement within the cell, from within the cell to the cell surface, or from one location to another at the surface of a cell. |
| GO:0071230 | | cellular response to amino acid stimulus | | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an amino acid stimulus. An amino acid is a carboxylic acids containing one or more amino groups. |
| GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| GO:0032008 | | positive regulation of TOR signaling | | Any process that activates or increases the frequency, rate or extent of TOR signaling. |
cellular component |
| GO:0071986 | | Ragulator complex | | A protein complex that contains MAPKSP1 (MP1, Map2k1ip1), ROBLD3 (p14, Mapbpip), C11orf59 (p18), LAMTOR4 and LAMTOR5. The complex is anchored to lipid rafts in late endosome membranes via C11orf59, recruits mTORC1 to lysosomal membranes in amino acid signaling to mTORC1, constitutes a guanine nucleotide exchange factor (GEF) for the Rag GTPases, and is also involved in ERK/MAPK signaling. |
| GO:0005768 | | endosome | | A vacuole to which materials ingested by endocytosis are delivered. |
| 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: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:0031902 | | late endosome membrane | | The lipid bilayer surrounding a late endosome. |
| GO:0005765 | | lysosomal membrane | | The lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm. |
| 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:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
