| molecular function |
|---|
| | GO:0005096 | | GTPase activator activity | | Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP. |
| | GO:0005089 | | Rho guanyl-nucleotide exchange factor activity | | Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rho family. 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: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). |
| biological process |
|---|
| | GO:0007254 | | JNK cascade | | An intracellular protein kinase cascade containing at least a JNK (a MAPK), a JNKK (a MAPKK) and a JUN3K (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:0006915 | | apoptotic process | | A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died. |
| | GO:0030032 | | lamellipodium assembly | | Formation of a lamellipodium, a thin sheetlike extension of the surface of a migrating cell. |
| | GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| | GO:0043065 | | positive regulation of apoptotic process | | Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process. |
| | GO:0035023 | | regulation of Rho protein signal transduction | | Any process that modulates the frequency, rate or extent of Rho protein signal transduction. |
| | GO:0051056 | | regulation of small GTPase mediated signal transduction | | Any process that modulates the frequency, rate or extent of small GTPase mediated signal transduction. |
| cellular component |
|---|
| | GO:0042995 | | cell projection | | A prolongation or process extending from a cell, e.g. a flagellum or axon. |
| | 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:0005622 | | intracellular | | The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. |
| | GO:0030027 | | lamellipodium | | A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments. |
