The ARF and Sar1 family GTPases are involved in COPI and COPII vesicle formation, which starts with the activation of ARF and Sar1 by a nucleotide exchange factor into ARF-GTP and Sar1-GTP.
This enzyme is involved in the ER-to-Golgi transport of proteins, where it has a function in protein cargo selection and in the assembly of the coat of COPII vesicles.
Mutations in a Sar1 GTPase of COPII vesicles are associated with lipid absorption disorders.
