ARFGEF1( Human )
ADP ribosylation factor guanine nucleotide exchange factor 1
Alias
ARFGEP1|BIG1|P200
ADP-ribosylation factors (ARFs) play an important role in intracellular vesicular trafficking. The protein encoded by this gene is involved in the activation of ARFs by accelerating replacement of bound GDP with GTP. It contains a Sec7 domain, which may be responsible for guanine-nucleotide exchange activity and also brefeldin A inhibition. [provided by RefSeq, Aug 2011].
