EOG8FBM6T GO:0005085 1/3 guanyl-nucleotide exchange factor activity molecular_function "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." [GOC:kd, GOC:mah] EOG8FBM6T GO:0007264 1/3 small GTPase mediated signal transduction biological_process "Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals." [GOC:mah] EOG8FBM6T GO:0051056 1/3 regulation of small GTPase mediated signal transduction biological_process "Any process that modulates the frequency, rate or extent of small GTPase mediated signal transduction." [GOC:go_curators] EOG8FBM6T GO:0005622 1/3 intracellular cellular_component "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." [ISBN:0198506732]
