Golgi coiled-coil proteins contain multiple binding sites for Rab family G proteins
Vesicles and other carriers destined for the Golgi apparatus must be guided to the correct cisternae. Golgins, long coiled-coil proteins that localize to particular Golgi subdomains via their C termini, are candidate regulators of vesicle sorting. In this study, we report that the GRIP domain golgins, whose C termini bind the Arf-like 1 G protein on the trans-Golgi, can also bind four members o...
متن کاملNomenclature for the human Arf family of GTP-binding proteins: ARF, ARL, and SAR proteins
The Ras superfamily is comprised of at least four large families of regulatory guanosine triphosphate-binding proteins, including the Arfs. The Arf family includes three different groups of proteins: the Arfs, Arf-like (Arls), and SARs. Several Arf family members have been very highly conserved throughout eukaryotic evolution and have orthologues in evolutionally diverse species. The different ...
متن کاملRab family small G proteins in regulation of epithelial apical junctions.
Tight junctions (TJs) and adherens junctions (AJs) comprise epithelial apical junctions that adhere neighboring epithelial cells and determine tissue organization. They are highly dynamic structures that undergo continuous remodeling during physiological morphogenesis and under pathological conditions. The assembly and disassembly of epithelial apical junctions is regulated by the interplay bet...
متن کاملThe Rab family of proteins: 25 years on.
Intracellular membrane trafficking requires the complex interplay of several classes of trafficking proteins. Rab proteins, the largest subfamily of the Ras superfamily of small G-proteins, are central regulators of all aspects of intracellular trafficking processes including vesicle budding and uncoating, motility, tethering and fusion. In the present paper, we discuss the discovery, evolution...
متن کاملEvolution of the Rab family of small GTP-binding proteins.
Rab proteins are small GTP-binding proteins that form the largest family within the Ras superfamily. Rab proteins regulate vesicular trafficking pathways, behaving as membrane-associated molecular switches. Here, we have identified the complete Rab families in the Caenorhabditis elegans (29 members), Drosophila melanogaster (29), Homo sapiens (60) and Arabidopsis thaliana (57), and we defined c...
