Research Interests

 Small GTPases form a large superfamily in which members are highly related in structures. The super family consists of several subfamilies such as Ras, Rho, Rab and Ran GTPases. They act as molecular switches in the regulation of cell division, cell growth, cell morphology, cell migration, membrane trafficking and transport of molecules. We are interested in the role of Rho and Rab GTPases in the regulation of cell growth, morphology and membrane trafficking. We are using the model organisms such as fission yeast and C. elegans in order to analyze the signal transduction pathways mainly by molecular genetics and cellular biology.
