Term Detail
GO term:ARF guanyl-nucleotide exchange factor activity
GO id:GO:0005086
Definition: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.
