Guanosine Triphosphate 174-177 Arf family GTPase ARF1 Saccharomyces cerevisiae S288C 192-196 18689681-2 2008 Here, we show that Arf1-GTP induces positive membrane curvature and find that the small GTPase can dimerize dependent on GTP. Guanosine Triphosphate 24-27 Arf family GTPase ARF1 Saccharomyces cerevisiae S288C 19-23 18689681-5 2008 Strikingly, this mutant was not able to deform membranes, suggesting that GTP-induced dimerization of Arf1 is a critical step inducing membrane curvature during the formation of coated vesicles.

Guanosine Triphosphate 89-92 Arf family GTPase ARF1 Saccharomyces cerevisiae S288C 123-127 10811810-3 2000 In this study, we investigated the role of coatomer in GTP hydrolysis on ARF1 both in solution and in a phospholipid environment.

Phospholipids 18-30 Arf family GTPase ARF1 Saccharomyces cerevisiae S288C 154-159 10811810-7 2000 Our findings suggest that in the biological membrane, the proximity between ARF1 and its GAP, which results from mutual binding to membrane phospholipids, may be sufficient for stimulation of ARF1 GTPase activity.

Guanine Nucleotides 54-72 Arf family GTPase ARF1 Saccharomyces cerevisiae S288C 85-96 9442017-7 1998 Taken together, these data are consistent with the hypothesis that selective recruitment of GRP1 to PtdIns(3,4,5)P3 in membranes activates ARF1 and -5, known regulators of intracellular membrane trafficking. phosphatidylinositol 3,4,5-triphosphate 100-115 Arf family GTPase ARF1 Saccharomyces cerevisiae S288C 139-150 8816753-8 1996 Moreover, cells with decreased levels of Arf1 or Arf2 protein, and thus with decreased levels of GTP-Arf, are markedly inhibited for growth by increased GCS1 gene dosage, presumably because increased levels of Gcs1 GAP activity further decrease GTP-Arf levels.
