Oligomerization regulates the localization of Cdc24, the Cdc42 activator in Saccharomyces cerevisiaeCyril Mionnet
Institute of Developmental Biology and Cancer, CNRS UMR 6543, Universite de Nice, Faculté des Sciences Parc Valrose, 06108 Nice Cedex 2, France
J Biol Chem 283:17515-30. 2008..Together, our results suggest that Cdc24p oligomerization regulates Cdc42p activation via its localization...
Activation of Rac1 by the guanine nucleotide exchange factor Dck1 is required for invasive filamentous growth in the pathogen Candida albicansHannah Hope
Institute of Developmental Biology and Cancer, Centre National de la Recherche Scientifique, Unité Mixte de Recherche 6543, Universite de Nice, Faculté des Sciences Parc Valrose, 06108 Nice Cedex 2, France
Mol Biol Cell 19:3638-51. 2008..We conclude that specific exchange factors, together with the G proteins they activate, are required for morphological changes in response to different stimuli...
Cdc42p GDP/GTP cycling is necessary for efficient cell fusion during yeast matingSophie Barale
Institute of Signaling, Developmental Biology, and Cancer, Centre National de la Recherche Scientifique UMR 6543, Universite de Nice, Faculté des Sciences Parc Valrose, 06108 Nice Cedex 2, France
Mol Biol Cell 17:2824-38. 2006..Taken together, our results indicate that Cdc42p GDP-GTP cycling is critical for efficient cell fusion...
Regulation of the Cdc42/Cdc24 GTPase module during Candida albicans hyphal growthMartine Bassilana
Institute of Signaling, Developmental Biology, and Cancer, UMR 6543 Centre National de la Recherche Scientifique, Centre de Biochimie, University of Nice, 06108 Nice, France
Eukaryot Cell 4:588-603. 2005..These results suggest that a positive feedback loop between Cdc24 and Tec1 contributes to an increase in active Cdc42 at the tip of the germ tube which is important for hypha formation...
The Candida albicans ELMO homologue functions together with Rac1 and Dck1, upstream of the MAP Kinase Cek1, in invasive filamentous growthHannah Hope
Institute of Developmental Biology and Cancer, CNRS UMR 6543, Universite de Nice Sophia Antipolis, Faculté des Sciences Parc Valrose, 06108 Nice Cedex 2, France
Mol Microbiol 76:1572-90. 2010..We conclude that the requirement of ELMO/CED12 family members for Rac1 function is conserved from fungi to humans...
Cdc24, the GDP-GTP exchange factor for Cdc42, is required for invasive hyphal growth of Candida albicansMartine Bassilana
Institute of Signaling, Developmental Biology, and Cancer, UMR 6543 Centre National de la Recherche Scientifique, University of Nice, 06108 Nice, France
Eukaryot Cell 2:9-18. 2003..These results indicate that a specific regulation of Cdc24/Cdc42 activity is required for invasive hyphal growth and suggest that these proteins are required for pathogenicity of C. albicans...

Institute of Biology Valrose, université Nice Sophia Antipolis, 06108 Nice Cedex 2, France
J Cell Biol 198:711-30. 2012..Furthermore, we propose that slow membrane diffusion of PI(4,5)P(2) contributes to the maintenance of such a gradient...
The exchange factor Cdc24 is required for cell fusion during yeast matingSophie Barale
