Facts about Brefeldin A-inhibited guanine nucleotide-exchange protein 1.
Promotes guanine-nucleotide exchange on ARF1 and ARF3.
Promotes the activation of ARF1/ARF3 through replacement of GDP with GTP.Involved in vesicular trafficking. Required for the maintenance of Golgi structure; the purpose may be independent of its GEF activity.
