Rho GTPases comprise a family of molecular switches that control signal transduction pathways in eukaryotic cells. A conformational change induced upon binding GTP promotes an interaction with target (effector) proteins to generate a cellular response. A highly conserved function of Rho GTPases from yeast to humans is to control the actin cytoskeleton,

Chronicles of the GTPase switch
Nature Chemical Biology, 2011The GTPase switch is a versatile molecular device used by many proteins, such as the small GTPases, to regulate an astounding number of functions. Although the basics of the guanine nucleotide cycle are now well established, the next challenge is to reach an integrated view of how these proteins use it to orchestrate signaling pathways.

The Rho (Ras-homologous) family of proteins constitutes a major branch of the Ras superfamily of small GTPases, and is evolutionarily conserved across several phyla. Thus far, 25 members have been identified, and these may be divided into 6 subfamilies based on amino acid sequence identity, structural motifs, and biological function.

AbstractRho GTPases are a family of small GTPases, which play an important role in the regulation of the actin cytoskeleton. Not surprisingly, Rho GTPases are crucial for cell migration and therefore highly important for cancer cell invasion and the formation of metastases. In addition, Rho GTPases are involved in growth and survival of tumor cells, in

Abstract GTPases are molecular switches that are used to control biochemical pathways. This book describes the properties and cellular roles of all the major families of GTPases: the G proteins, Ras, Rho, Rab, Arf, and Ran. All cells use GTPases to regulate the delivery of amino acids to the ribosome during protein synthesis, but ...

It is becoming increasingly clear that the complex family of Rho-related GTPases and their associated regulators and targets are essential mediators of a variety of morphogenetic events required for normal development of multicellular organisms. It is worth noting that the results obtained thus far indicate that the Rho family proteins are largely ...

Leucine-rich repeat kinase 2 (LRRK2) is mutated in familial Parkinson's disease, and pathogenic mutations activate the kinase activity. A tour de force screen by Mann and Alessi and co-workers identified a subset of Rab GTPases as bona fide LRRK2 substrates.

LRRK2 (leucine-rich repeat kinase 2) is a large protein encoding multiple functional domains, including two catalytically active domains, a kinase and a GTPase domain. The LRRK2 GTPase belongs to the Ras-GTPase superfamily of GTPases, more specifically to the ROC (Ras of complex proteins) subfamily.

GTPases in Semaphorin Signaling
2007A hallmark of semaphorin receptors is their interaction with multiple GTPases. Plexins, the signal transducing component of semaphorin receptors, directly associate with several GTPases. In addition, they not only recruit guaninine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs) but also are the only known integral membrane ...

Role of GTPases and GTPase regulatory proteins in oncogenesis.
Critical reviews in oncogenesis, 1993The GTPases comprise a superfamily of GTP-binding proteins with intrinsic GTPase activity. Some members of this family representing either heterotrimeric or small G-proteins are involved in the transmission of mitogenic signals. Mutations that lead to constitutively activated G-proteins have been shown to contribute to malignant transformation.
