A Rab10:RalA G protein cascade regulates insulin-stimulated glucose uptake in adipocytes. [PDF]
, 2014 Insulin-stimulated glucose uptake in fat and muscle is mediated by the major facilitative glucose transporter Glut4. Insulin controls the trafficking of Glut4 to the plasma membrane via regulation of a series of small G proteins, including RalA and Rab10.

Structural basis of guanine nucleotide exchange for Rab11 by SH3BP5
Life Science Alliance, 2019 The structure of the SH3BP5–Rab11a complex and structure-based mutational analyses reveal structural basis of nucleotide exchange for Rab11 by its specific guanine nucleotide exchange factor. The Rab GTPase family is a major regulator of membrane traffic

EspM2 is a RhoA guanine nucleotide exchange factor [PDF]
Cellular Microbiology, 2010 We investigated how the type III secretion system WxxxE effectors EspM2 of enterohaemorrhagic Escherichia coli, which triggers stress fibre formation, and SifA of Salmonella enterica serovar Typhimurium, which is involved in intracellular survival, modulate Rho GTPases.

This Is the End: Regulation of Rab7 Nucleotide Binding in Endolysosomal Trafficking and Autophagy
Frontiers in Cell and Developmental Biology, 2018 Rab7 – or in yeast, Ypt7p – governs membrane trafficking in the late endocytic and autophagic pathways. Rab7 also regulates mitochondrion-lysosome contacts, the sites of mitochondrial fission.

Mechanism of the exchange reaction in HRAS from multiscale modeling. [PDF]
PLoS ONE, 2014 HRAS regulates cell growth promoting signaling processes by cycling between active (GTP-bound) and inactive (GDP-bound) states. Understanding the transition mechanism is central for the design of small molecules to inhibit the formation of RAS-driven ...

Signal Recognition Particle (SRP) and SRP Receptor: A New Paradigm for Multistate Regulatory GTPases [PDF]
, 2009 The GTP-binding proteins or GTPases comprise a superfamily of proteins that provide molecular switches in numerous cellular processes. The “GTPase switch” paradigm, in which a GTPase acts as a bimodal switch that is turned “on” and “off” by external ...
