Resumen: | Rab3D, a small Ras-like GTPase, is a key regulator of intracellular vesicle transport during exocytosis. It has been shown that Rab3 GTPases are abundant in cells with regulated secretory pathways and are thought to confer the specificity of docking and fusion during regulated exocytosis. Unlike other Rab3 isoforms, Rab3D is enriched in a number of nonneuronal tissues and is localised to secretory granules in the cytoplasm of these cells. The structure of Rab3D exhibits all of the conserved domains from the Rab family and also contains hypervariable N- and Cterminal regions. Rab3D undergoes post-translational isoprenylation and cycles between GDP- and GTPbound forms. Apart from the factors involved in the Rab activation cycle, few Rab3D effector proteins have been identified to date. Nevertheless, it has long been suggested that Rab3D plays a role in regulated exocytotic processes as well as apically directed transcytosis. This review summarises the recent work on the biological function, structural integrity and molecular interactions of Rab3D in non-neuronal cells. |
