| molecular function |
|---|
| | GO:0005088 | | Ras guanyl-nucleotide exchange factor activity | | Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Ras superfamily. 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:0003779 | | actin binding | | Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments. |
| | GO:0005543 | | phospholipid binding | | Interacting selectively and non-covalently with phospholipids, a class of lipids containing phosphoric acid as a mono- or diester. |
| | GO:0005200 | | structural constituent of cytoskeleton | | The action of a molecule that contributes to the structural integrity of a cytoskeletal structure. |
| biological process |
|---|
| | GO:0006888 | | ER to Golgi vesicle-mediated transport | | The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi. |
| | GO:0000165 | | MAPK cascade | | An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain two additional tiers: the upstream MAP4K and the downstream MAP Kinase-activated kinase (MAPKAPK). The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell. |
| | GO:0051693 | | actin filament capping | | The binding of a protein or protein complex to the end of an actin filament, thus preventing the addition, exchange or removal of further actin subunits. |
| | GO:0030534 | | adult behavior | | Behavior in a fully developed and mature organism. |
| | GO:0019886 | | antigen processing and presentation of exogenous peptide antigen via MHC class II | | The process in which an antigen-presenting cell expresses a peptide antigen of exogenous origin on its cell surface in association with an MHC class II protein complex. The peptide antigen is typically, but not always, processed from a whole protein. |
| | GO:0007411 | | axon guidance | | The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues. |
| | GO:0071361 | | cellular response to ethanol | | 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 ethanol stimulus. |
| | GO:0021692 | | cerebellar Purkinje cell layer morphogenesis | | The process in which the anatomical structure of the cerebellar Purkinje cell layer is generated and organized. The Purkinje cell layer lies just underneath the molecular layer of the cerebellar cortex. It contains the neuronal cell bodies of the Purkinje cells that are arranged side by side in a single layer. Candelabrum interneurons are vertically oriented between the Purkinje cells. Purkinje neurons are inhibitory and provide the output of the cerebellar cortex through axons that project into the white matter. Extensive dendritic trees from the Purkinje cells extend upward in a single plane into the molecular layer where they synapse with parallel fibers of granule cells. |
| | GO:0035264 | | multicellular organism growth | | The increase in size or mass of an entire multicellular organism, as opposed to cell growth. |
| | GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| | GO:0007416 | | synapse assembly | | The aggregation, arrangement and bonding together of a set of components to form a synapse. This process ends when the synapse is mature (functional). |
| | 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:0000139 | | Golgi membrane | | The lipid bilayer surrounding any of the compartments of the Golgi apparatus. |
| | GO:0016324 | | apical plasma membrane | | The region of the plasma membrane located at the apical end of the cell. |
| | GO:0005938 | | cell cortex | | The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins. |
| | GO:0030054 | | cell junction | | A cellular component that forms a specialized region of connection between two or more cells or between a cell and the extracellular matrix. At a cell junction, anchoring proteins extend through the plasma membrane to link cytoskeletal proteins in one cell to cytoskeletal proteins in neighboring cells or to proteins in the extracellular matrix. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0005856 | | cytoskeleton | | Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles. |
| | 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:0005768 | | endosome | | A vacuole to which materials ingested by endocytosis are delivered. |
| | GO:0005615 | | extracellular space | | That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. |
| | GO:0043025 | | neuronal cell body | | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
| | GO:0048471 | | perinuclear region of cytoplasm | | Cytoplasm situated near, or occurring around, the nucleus. |
| | 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:0008091 | | spectrin | | Membrane associated dimeric protein (240 and 220 kDa) of erythrocytes. Forms a complex with ankyrin, actin and probably other components of the membrane cytoskeleton, so that there is a mesh of proteins underlying the plasma membrane, potentially restricting the lateral mobility of integral proteins. |
| | GO:0008021 | | synaptic vesicle | | A secretory organelle, typically 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane. |
