Eps8, originally identified as a substrate for the kinase activity of the epidermal growth factor receptor (EGFR), displays a domain organization typical of a signaling molecule that includes a putative N-terminal PTB domain, a central SH3 domain, and a C-terminal "effector region".

Rho GTPases regulate many important processes in all eukaryotic cells, including the organization of the actin cytoskeleton, gene transcription, cell cycle progression, and membrane trafficking. Their activity is regulated by signals originating from different classes of surface receptors including G-protein-coupled receptors, tyrosine kinase receptors,

GTPases represent a large family of proteins involved in a wide variety of cellular processes. They function as switches in which they are "on" in the GTP bound state and "off" in the GDP bound state. The "on" and "off" states are regulated by proteins which interact with the GTPases and enhance their rate of either GTP hydrolysis or GDP-GTP exchange ...

Current Opinion in Cell Biology, 1999
The Rho GTPases are simple enzymes with complex roles in regulating cell morphology, gene transcription, cell cycle progression, apoptosis and tumour progression. The picture has been further complicated by the steady rise in the number of known Rho GTPases as well as in the number of known regulators and target proteins of these GTPases.

The RAS oncogenes were identified almost 20 years ago. Since then, we have learnt that they are members of a large family of small GTPases that bind GTP and hydrolyse it to GDP. This is then exchanged for GTP and the cycle is repeated. The switching between these two states regulates a wide range of cellular processes.

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,

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.

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.

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 ...

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
