EOG8GXJ6F GO:0005085 2/2 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] EOG8GXJ6F GO:0007264 2/2 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."
