guanyl-nucleotide exchange factor activity

id: GO:0005085
name: guanyl-nucleotide exchange factor activity
namespace: molecular_function
type: go
obsolete: False

Description: 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.
