In eukaryotes it includes the nucleus and cytoplasm."

[GOC:go_curators] EOG8B5RKQ GO:0005085 1/19 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]
