molecular function |
| GO:0001664 | | G-protein coupled receptor binding | | Interacting selectively and non-covalently with a G-protein coupled receptor. |
| 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:0007186 | | G-protein coupled receptor signaling pathway | | A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576). |
| 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:0030036 | | actin cytoskeleton organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins. |
| GO:0000910 | | cytokinesis | | The division of the cytoplasm and the plasma membrane of a cell and its partitioning into two daughter cells. |
| GO:0030010 | | establishment of cell polarity | | The specification and formation of anisotropic intracellular organization or cell growth patterns. |
| GO:0006928 | | movement of cell or subcellular component | | The directed, self-propelled movement of a cell or subcellular component without the involvement of an external agent such as a transporter or a pore. |
| 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:0045893 | | positive regulation of transcription, DNA-templated | | Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0035023 | | regulation of Rho protein signal transduction | | Any process that modulates the frequency, rate or extent of Rho protein signal transduction. |
| GO:0001558 | | regulation of cell growth | | Any process that modulates the frequency, rate, extent or direction of cell growth. |
| GO:0051056 | | regulation of small GTPase mediated signal transduction | | Any process that modulates the frequency, rate or extent of small GTPase mediated signal transduction. |
| GO:0006941 | | striated muscle contraction | | A process in which force is generated within striated muscle tissue, resulting in the shortening of the muscle. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. Striated muscle is a type of muscle in which the repeating units (sarcomeres) of the contractile myofibrils are arranged in registry throughout the cell, resulting in transverse or oblique striations observable at the level of the light microscope. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| 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:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
