Abstract:
Rab proteins are necessary for membrane fusion and fission and as such are key regulators of intracellular transport in eukaryotic cells. They also control other aspects of cell functioning, including the cytoskeleton rearrangements, determination of cell polarity or signal transduction. Rab proteins exert their control both indirectly, because they decide whether all necessary proteins and other cargo reach their correct destinations in the cell, and directly, through interactions of their active forms with effector proteins. Therefore, the results of Rab dysfunctions manifest themselves on all levels of biological organization â from cells, through tissues and organs, to whole organisms. In plants, Rab-dependent processes are important for cell architecture, differentiation, reactions to biotic and abiotic stress, as well as for the efficiency of agricultural production.

Rab Proteins
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
