(i.e., Ras, Rac, Cdc42 and RhoA), and Ran1
diverse array of cellular processes. It is known that these
small GTPases are
redox active and aberration of their activity can lead to an increase in
the amount of the biologically active form of GTPases which can promote
uncontrolled cell growth. It is also well known that Ras is the most
prevalent oncoprotein found in human cancer.
