ADP-ribosylation factor GTPase activating protein 1

ARF GAP, ARFGAP1, ADP-ribosylation factor GTPase-activating protein, GAP protein
The protein encoded by this gene is a GTPase-activating protein (GAP) which associates with the Golgi apparatus and which interacts with ADP-ribosylation factor 1 (ARF1). The encoded protein promotes hydrolysis of ARF1-bound GTP and is required for the dissociation of coat proteins from Golgi-derived membranes and vesicles. Dissociation of the coat proteins is required for the fusion of these vesicles with target compartments. The activity of this protein is stimulated by phosphoinosides and inhibited by phosphatidylcholine. Two transcript variants encoding different isoforms have been found for this gene.

Gravitropism in Arabidopsis thaliana: Root-specific action of the EHB gene and violation of the resultant law.
Galland et al., Marburg an der Lahn, Germany. In J Plant Physiol, Oct 2015
A tropism mutant lacking the EHB1 protein, which interacts with ARF-GAP (ARF GTPase-activating protein) and thus indirectly with a small ARF-type G protein, displayed a lower gravitropic threshold for roots and also enhanced bending, while the responses of the hypocotyls remained nearly unaffected.

The second critical region included the ArfGAP1 gene, which encodes a conserved GTPase-activating protein with specificity towards GTPases of the Arf family.
Interaction of LRRK2 with kinase and GTPase signaling cascades.
Wolozin et al., Boston, United States. In Front Mol Neurosci, 2013
Binding to GTPases, GTPase-activating proteins and GTPase exchange factors are another strong theme in LRRK2 biology, with LRRK2 binding to rac1, cdc42, rab5, rab7L1, endoA, RGS2, ArfGAP1, and ArhGEF7.

ARFGAP1 promotes AP-2-dependent endocytosis.
Hsu et al., Boston, United States. In Nat Cell Biol, 2011
role of ARFGAP1 in AP-2-regulated endocytosis has mechanistic parallels with its roles in COPI transport, as both its GAP activity and coat function contribute to promoting AP-2 transport

Asymmetric tethering of flat and curved lipid membranes by a golgin.
Antonny et al., Antibes, France. In Science, 2008
This asymmetric tethering relied on motifs that sensed membrane curvature both in the N terminus of GMAP-210 and in ArfGAP1, which controlled the interaction of the C terminus of GMAP-210 with the small guanine nucleotide-binding protein Arf1.
