    basic FUNCTION
  • involved in the activation of the GTPase activity of ARF
  • promoting hydrolysis of ARF1-bound GTP and is required for the dissociation of coat proteins from Golgi-derived membranes and vesicles
  • control guanosine triphosphate (GTP) hydrolysis on the small G protein ADP-ribosylation factor ARF1 at the Golgi apparatus
  • involved in retrograde transport from the Golgi apparatus to the endoplasmic reticulum (ER) by regulating the uncoating of coat protein I (COPI)-coated vesicles
  • ARFGAP1, ARFGAP2, and ARFGAP3 have overlapping roles in regulating COPI function in Golgi-to-ER retrograde transport
  • role of ARFGAP1 in AP-2-regulated endocytosis that has mechanistic parallels with its roles in COPI transport
