}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 and characterization of the Rab GTPase family. We examine their basic functional roles, their…

Analysis supports a scenario where Rabs differentiated into an independent family in Archaea, interacting with proteins involved in membrane biogenesis and provides a new insight into the intermediate stages and the evolutionary path toward the complex membrane-associated signaling circuits that characterize the Ras superfamily of small GTPases, and specifically Rab proteins.

Human Golgi phosphoprotein 3 is an effector of RAB1A and RAB1B
- BiologyPloS one

It is shown that human GOLPH3 interacted directly with either RAB1A or RAB 1B, the two isoforms of R AB1 in humans, indicating that human golgi phosphoprotein 3 is a bona fide effector of RAB2 and RAB3, both of which are proteins of the RAB family of small GTPases.

Rabs and their effectors: Achieving specificity in membrane traffic
- Biology, ChemistryProceedings of the National Academy of Sciences
- 2006
Rab proteins constitute the largest branch of the Ras GTPase superfamily and certain effectors act to establish positive feedback loops that help to define and maintain tightly localized domains of activated Rab proteins, which then serve to recruit other effector molecules.

Crosstalk between multiple Rab GTPases through shared effectors, or through effectors that recruit selective Rab activators, ensures the spatiotemporal regulation of vesicle traffic.

This work identified the complete Rab families in the Caenorhabditis elegans, Drosophila melanogaster, Homo sapiens and Arabidopsis thaliana, and defined criteria for annotation of this protein family in each organism, and observed that Rabs co-segregating in phylogenetic trees show a pattern of similar cellular localisation and/or function.

It is concluded that the hypervariable region of the Rab family does not contain a general Rab targeting signal, and other regions within the RabF and RabSF motifs that are required for specific targeting of Rab27a to secretory granules or melanosomes, and Rab5a to endosomes are identified.

It is demonstrated that dissociation from REP‐1 and binding of rab proteins to the membrane do not require RabGDI or other cytosolic factors, and the mechanism of REP-1‐mediated membrane association of rab5 appears to be very similar to that mediated by RabG DI.
