Research Abstract |
The small GTPase RalA regulates many cellular processes such as cell proliferation, migration, membrane traffic, and tumorigenesis. Accumulating evidence shows that activation of RalA GTPase is essential for oncogenic Ras-induced human cell tumorigenesis. However, the molecular mechanism by which RalA regulates tumorigenesis remains elusive. I tried to identify RalA effector proteins in rat brain cytosol and succeeded in purifying a RalA effector complex using several chromatography steps including ammonium sulphate precipitation, ion-exchange chromatograhpy, and RalA affinity chromatography. This effector complex may be involved in RalA-dependent tumorigenesis.
