Rab11 in Disease Progression
Membrane/ protein trafficking in the secretory/ biosynthetic and endocytic pathways is mediated by vesicles. Vesicle trafficking in eukaryotes is regulated by a class of small monomeric GTPases the Rab protein family. Rab proteins represent the largest branch of the Ras superfamily GTPases, and have been concerned in a variety of intracellular vesicle trafficking and different intracellular sig...
متن کاملRab GTPases-Dependent Endocytic Pathways Regulate Neuronal Migration and Maturation through N-Cadherin Trafficking
Although membrane trafficking pathways are involved in basic cellular functions, the evolutionally expanded number of their related family proteins suggests additional roles for membrane trafficking in higher organisms. Here, we show that several Rab-dependent trafficking pathways differentially participate in neuronal migration, an essential step for the formation of the mammalian-specific six...
متن کاملTBC1D12 is a novel Rab11-binding protein that modulates neurite outgrowth of PC12 cells
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...
متن کامل[Rab GTPases networks in membrane traffic in Saccharomyces cerevisiae].
Intracellular membrane trafficking between membranous compartments is essential for organelle biogenesis, structure, and identity. Rab/Ypt GTPases are well-characterized regulators of intracellular membrane trafficking, functioning as molecular switches that alternate between GTP- and GDP-bound forms. In Saccharomyces cerevisiae, 11 Rab/Ypt GTPases have been identified and their functions are k...
متن کاملRab proteins and the compartmentalization of the endosomal system.
Of the approximately 70 human Rab GTPases, nearly three-quarters are involved in endocytic trafficking. Significant plasticity in endosomal membrane transport pathways is closely coupled to receptor signaling and Rab GTPase-regulated scaffolds. Here we review current literature pertaining to endocytic Rab GTPase localizations, functions, and coordination with regulatory proteins and effectors. ...
