  • small GTPase superfamily
  • ADP-ribosylation factors (ARF) family
  • CATEGORY enzyme , receptor membrane G
    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • guanine nucleotide dependent protein activator of cholera toxin, involved in the coating of vesicles that bud from Golgi compartments and vesicular trafficking,
  • through interaction with ARF exchange factor
  • playing a crucial role in protein trafficking
  • active during mitosis and this activity is required for mitotic Golgi fragmentation
  • with ARF6, load GTP in a membrane-curvature-dependent manner and stabilize, or further facilitate, changes in membrane curvature through the insertion of an amphipathic helix
  • monomeric GTPases that is important regulator of membrane traffic
  • plays an essential role in regulating asymmetric cell division in female meiosis
  • modulator of VEGF-stimulated NO(nitric oxide) release and signaling in endothelial cells
  • ARF1 and AGAP2 have key trafficking functions at the interface between early endosomes and the TGN
  • ARF1, ARF4 regulate morphology and intraorganellar traffic in the endoplasmic reticulum-Golgi intermediate compartment
  • required for maintenance of Golgi architecture and for vesicular trafficking, including the copper-responsive trafficking of ATP7A
  • essential cofactor for TP53-independent MYC-induced apoptosis
  • role in controlling cell proliferation, dependent on its ability to regulate RB1/E2F1 activity and gene expression for enhanced proliferation and breast cancer progression
  • regulates Golgi traffic and is activated by two related types of guanine nucleotide exchange factor (GEF)
  • ARF1 and ARF4 regulate recycling endosomal morphology and retrograde transport from endosomes to the Golgi apparatus
  • concerted action of of ARF1, ARHGAP21, and Cdc42 to regulate fluid phase endocytosis in mammalian cells ('
    metabolism carbohydrate
    a component
  • CYTH2-ARF1 regulates formation of podosomes by inhibition of RHOA/myosin-II and promotion of actin core assembly
    small molecule
  • low molecular weight GTP binding
  • interacting with PRKCABP, ARFGAP1, which hydrolyzes GTP and binding DDEF2 thus, regulates its function
  • binds DDEF2
  • interaction with IQSEC3 (may play an important role in the secretion pathway as a GEF for ARF1)
  • dynein and microtubule-dependent Golgi positioning is regulated by ARF1-, coatomer-, and ARHGAP21-dependent CDC42 signaling
  • ARL1 acts to direct a trans-Golgi-specific ARF1 GEF, and hence active ARF1, to the trans side of the Golgi (PMID;
  • ARAP1 regulates the ring size of circular dorsal ruffles through ARF1 and ARF5
  • ELMOD2 exhibited GAP activity against ARL2, ARL3, and ARF1
  • interaction of PLEKHA3 with ARF1 and PI4P at a membrane surface
  • concerted action of ARF1, ARHGAP21, and CDC42 to regulate fluid phase endocytosis
  • ARF1/TBCE-mediated cross-talk that coordinates COPI formation and tubulin polymerization at the Golgi
