TLDR
The observation that WAS is the result of defects in signal transduction pathways regulated by Cdc42/Rac and Nck is suggested to suggest that the protein is defective in patients suffering from the disease.About:

Small GTP-Binding Proteins
TL;DR: In this review, functions of small G proteins and their modes of activation and action are described.
Journal ArticleDOI
Rho GTPases and signaling networks
TL;DR: The Rho GTPases form a subgroup of the Ras superfamily of 20- to 30-kD GTP-binding proteins that have been shown to regulate a wide spectrum of cellular functions, and some of the more recent exciting findings hinting at novel, unanticipated functions of the RhoGTPases are summarized.

Rho GTPases and their effector proteins.
Anne L. Bishop,Alan Hall +1 more
TL;DR: The main focus of this review will be Rho, Rac and Cdc42, the three best characterized mammalian Rho GTPases, though the genetic analysis of RhoGTPases in lower eukaryotes is making increasingly important contributions to this field.

Scar1 and the related Wiskott–Aldrich syndrome protein, WASP, regulate the actin cytoskeleton through the Arp2/3 complex
TL;DR: The data suggest that WASP-related proteins may regulate the actin cytoskeleton through the Arp2/3 complex.
Journal ArticleDOI
The WASP-WAVE protein network: connecting the membrane to the cytoskeleton.
TL;DR: Wiskott–Aldrich syndrome protein (WASP) and WASP-family verprolin-homologous protein (WAVE) family proteins are scaffolds that link upstream signals to the activation of the ARP2/3 complex, leading to a burst of actin polymerization.

Molecular Cloning: A Laboratory Manual
TL;DR: Molecular Cloning has served as the foundation of technical expertise in labs worldwide for 30 years as mentioned in this paper and has been so popular, or so influential, that no other manual has been more widely used and influential.

TL;DR: A novel genetic system to study protein-protein interactions between two proteins by taking advantage of the properties of the GAL4 protein of the yeast Saccharomyces cerevisiae, which may be applicable as a general method to identify proteins that interact with a known protein by the use of a simple galactose selection.

Rho, Rac, and Cdc42 GTPases regulate the assembly of multimolecular focal complexes associated with actin stress fibers, lamellipodia, and filopodia
Catherine D. Nobes,Alan Hall +1 more
TL;DR: It is reported here that cdc42, another member of the rho family, triggers the formation of a third type of actin-based structure found at the cell periphery, filopodia, in addition to stress fibers, and rho controls the assembly of focal adhesion complexes.

The small GTP-binding protein rho regulates the assembly of focal adhesions and actin stress fibers in response to growth factors.
Anne J. Ridley,Alan Hall +1 more
TL;DR: Rho, a ras-related GTP-binding protein, rapidly stimulated stress fiber and focal adhesion formation when microinjected into serum-starved Swiss 3T3 cells, implying that rho is essential specifically for the coordinated assembly of focal adhesions and stress fibers induced by growth factors.
Journal ArticleDOI
The small GTP-binding protein rac regulates growth factor-induced membrane ruffling.
TL;DR: It is proposed that rac and rho are essential components of signal transduction pathways linking growth factors to the organization of polymerized actin and that growth factors act through rac to stimulate this rho-dependent response.
