The human genome encodes approximately 70 Rab GTPases that localize to the surfaces of distinct membrane compartments. To investigate the mechanism of Rab localization, chimeras containing heterologous Rab hypervariable domains were generated, and their ability to bind seven Rab effectors was quantified. Two chimeras could bind effectors for two distinctly localized Rabs; a Rab5/9 hybrid bound ...
Mutations that activate the LRRK2 (leucine-rich repeat protein kinase 2) protein kinase predispose to Parkinson's disease, suggesting that LRRK2 inhibitors might have therapeutic benefit. Recent work has revealed that LRRK2 phosphorylates a subgroup of 14 Rab proteins, including Rab10, at a specific residue located at the centre of its effector-binding switch-II motif. In the present study, we ...
Dense core vesicles (DCVs) are thought to be generated at the late Golgi apparatus as immature DCVs, which subsequently undergo a maturation process through clathrin-mediated membrane remodeling events. This maturation process is required for efficient processing of neuropeptides within DCVs and for removal of factors that would otherwise interfere with DCV release. Previously, we have shown th...
Over 60 distinct Rab GTPases regulate specific vesicular transport steps in the mammalian central vacuolar system. Wasmeier et al. (this issue, p. 271) reveal a redundant role for two tissue-specific Rab proteins in regulating transport to a tissue-specific lysosome-related organelle, the melanosome.
The endocytic pathway of eukaryotes is essential for the internalization and trafficking of macromolecules, fluid, membranes, and membrane proteins. One of the most enigmatic aspects of this process is endocytic recycling, the return of macromolecules (often receptors) and fluid from endosomes to the plasma membrane. We have previously shown that the EH-domain protein RME-1 is a critical regula...
Recycling endosomes are generally thought to play a central role in endocytic recycling, but recent evidence has indicated that they also participate in other cellular events, including cytokinesis, autophagy, and neurite outgrowth. Rab small GTPases are key regulators in membrane trafficking, and although several Rab isoforms, e.g., Rab11, have been shown to regulate recycling endosomal traffi...
