EOG8M946Z GO:0032012 3/6 regulation of ARF protein signal transduction biological_process "Any process that modulates the frequency, rate or extent of ARF protein signal transduction." [GOC:mah] EOG8M946Z GO:0005086 3/6 ARF guanyl-nucleotide exchange factor activity molecular_function "Stimulates the exchange of guanyl nucleotides associated with the GTPase ARF. 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:mah]
