Rab GTPases coordinate endocytosis.
Endocytosis is characterized by vesicular transport along numerous pathways. Common steps in each pathway include membrane budding to form vesicles, transport to a particular destination, and ultimately docking and fusion with the target membrane. Specificity of vesicle targeting is rendered in part by associated Rab GTPases. This review summarizes current knowledge about Rab GTPase functions i...
متن کاملGeranylgeranylation of Rab GTPases
Rab GTPases require special machinery for protein prenylation, which include Rab escort protein (REP) and Rab geranylgeranyl transferase (RGGT). The current model of Rab geranylgeranylation proposes that REP binds Rab and presents it to RGGT. After geranylgeranylation of Rab C-terminal cysteines, REP delivers the prenylated protein to membranes. The REP-like protein Rab GDP dissociation inhibit...
متن کاملRab GTPases at a glance.
There was an error published in J. Cell Sci. 120, 3905-3910. The authors regret that in Table 1 under ‘(13) Rab1, Rab3, Rab8, Rab10, Rab12, Rab13, Rab15, Rab35, Rab40’, Rab35 was incorrectly referred to as an uncharacterized member of the Rab family. The correct details are given below. Rab Localization Function Reference Rab35 Plasma membrane, endosomes, intercellular bridge Rapid endocytic re...
متن کاملRab GTPases and microtubule motors.
Rab proteins are a family of small GTPases which, since their initial identification in the late 1980s, have emerged as master regulators of all stages of intracellular trafficking processes in eukaryotic cells. Rabs cycle between distinct conformations that are dependent on their guanine-nucleotide-bound status. When active (GTP-bound), Rabs are distributed to the cytosolic face of specific me...
متن کاملRab GTPases as regulators of endocytosis, targets of disease and therapeutic opportunities
Rab GTPases are well-recognized targets in human disease, although are underexplored therapeutically. Elucidation of how mutant or dysregulated Rab GTPases and accessory proteins contribute to organ specific and systemic disease remains an area of intensive study and an essential foundation for effective drug targeting. Mutation of Rab GTPases or associated regulatory proteins causes numerous h...
