13. ARF1 may reverse CAM-DR by regulating phosphorylation of p27 at T157 in MM. our data shed new light on the molecular mechanism of CAM-DR in MM, and targeting ARF1 may be a novel therapeutic approach for improving the effectiveness of chemotherapy in MM.

14. We report here that 2-methylcoprophilinamide (M-COPA), a compound that induces disassembly of the Golgi apparatus by inactivating ADP-ribosylation factor 1 (Arf1), suppresses Stx-induced apoptosis. M-COPA inhibited transport of Stx from the plasma membrane to the Golgi apparatus and suppressed degradation of anti-apoptotic proteins and the activation of caspases

15. observations indicate that Arf1 and Arf3 as well as Arf6 play important roles in cytokinesis.

16. ARF1 activates the MAPK pathway likely using the Golgi as a main platform, which in turn activates the cytoplasmic RSK1, leading to cell proliferation.

17. Data indicate that ADP-ribosylation factor 1 (Arf1) colocalizes with chromogranin A and regulates secretion of insulin like growth factor 1 (IGF-1) and is required for anchorage dependent growth.

18. this study reports the cryo-electron microscopy structures of the Nef- and Arf1-bound AP-1 trimer in the active and inactive states.

19. Suggest a model in which Arf1/COPI machinery acts to control endoplasmic reticulum-lipid droplet connections for localization of key enzymes of triglyceride storage and catabolism.

20. ARF1 regulates cellularmigration of highly invasive triple-negative breast cancer cells, through the regulation of the focal adhesions complex.

Mouse (Murine) ADP-Ribosylation Factor 1 (ARF1) interaction partners

1. The authors found that Arf1 occupies contrasting molecular environments within the Coat Protein Complex I, leading them to hypothesize that some Arf1 molecules may regulate vesicle assembly while others regulate coat disassembly.

2. ARF1 may be a plausible inter-player that mediates the transition to osteoclast fusion at multiple steps during osteoclast differentiation.

3. Increased gene dosage of Ink4a, Arf1 and p53 delays age-associated central nervous system functional decline.

4. ARF1/TBCE-mediated cross-talk that coordinates COPI formation and tubulin polymerization at the Golgi.

5. These data establish for the first time that the Arf1 gene is indispensable for mouse embryonic development after implantation.

6. Arf modulates LRP6 phosphorylation for the transduction of Wnt/beta-catenin signaling.

7. Down-regulation of ADP-ribosylation factor results in corneal neovascularization regression.

8. ARF1-dependent trafficking of procathepsin B and the maturation of autophagosomes results in cathepsin B-mediated trypsinogen activation induced by caerulein.

9. Egr1 mediates p53-independent c-Myc-induced apoptosis via a noncanonical ARF-dependent transcriptional mechanism

10. A senescence rescue screen identifies BCL6 as an inhibitor of anti-proliferative p19(ARF)-p53 signaling

11. termination of Arf1 signals mediated through GGA require that Arf1.GTP dissociates from GGA prior to interaction with GAP and consequent hydrolysis of GTP

12. GDP-bound ARF1 induces dissociation of ADRP from the Lipid droplet surface.

13. The recruitment of certain adhesion components such as paxillin requires dynamic GTP/GDP turnover of Arf1 GTPase.

14. The crystal structure of the activated GTP-bound form of ARF1 in a complex with the Arf-binding domain (ArfBD) of ARHGAP21 at 2.1 A resolution, is presented.

15. ARF1 plays an essential role in regulating asymmetric cell division in female meiosis.

Zebrafish ADP-Ribosylation Factor 1 (ARF1) interaction partners

1. findings reveal a novel signalling pathway involved in development of the semicircular canal system, and suggest a previously unrecognized role for NCS-1 in mitochondrial function via its association with several mitochondrial proteins.

Cow (Bovine) ADP-Ribosylation Factor 1 (ARF1) interaction partners

1. Vascular endothelial growth factor receptor-2 activates ADP-ribosylation factor 1 to promote endothelial nitric-oxide synthase activation and nitric oxide release from endothelial cells

2. Data show that AP-1 recruitment to the cell membrane was found to be dependent on myristoylated ADP-ribosylation factor (ARF1), GTP or nonhydrolyzable GTP-analogs, tyrosine signals, and small amounts of phosphoinositides.

3. NCS-1-ARF1 interaction provides evidence for functional cross-talk between Ca(2+)-dependent and ARF-dependent pathways in TGN to plasma membrane traffic

4. The ARF1 machinery also might produce movement- and fission-promoting forces through actin polymerization.

Arabidopsis thaliana ADP-Ribosylation Factor 1 (ARF1) interaction partners

1. Study shows that ARF DNA-binding domains ahomodimerize to generate cooperative DNA binding, which is critical for in vivo ARF5/MP function. Strikingly, DNA-contacting residues are conserved between ARFs, and found that monomers have the same intrinsic specificity; ARF1 and ARF5 homodimers, however, differ in spacing tolerated between binding sites.

2. Data indicate that ArfGAP domain8 (AGD8) and ARF-GAP domain 9 (AGD9), are involved in the recruitment of Arf1-GDP to the Golgi apparatus .
