EOG88SK7C GO:0005085 23/53 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] EOG88SK7C GO:0007264 23/53 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] EOG88SK7C GO:0005622 23/53 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]
