Characterization of Novel Derivatives of MBQ-167, an Inhibitor of the GTP-binding Proteins Rac/Cdc42
Rac and Cdc42, are homologous GTPases that regulate cell migration, invasion, and cell-cycle progression; thus, representing key targets for metastasis therapy. We previously reported on the efficacy of MBQ-167, which blocks both Rac1 and Cdc42 in breast cancer cells and mouse models of metastasis. To identify compounds with increased activity, a panel

Structure of the Rho Family GTP-Binding Protein Cdc42 in Complex with the Multifunctional Regulator RhoGDI [PDF]
The RhoGDI proteins serve as key multifunctional regulators of Rho family GTP-binding proteins. The 2.6 A X-ray crystallographic structure of the Cdc42/RhoGDI complex reveals two important sites of interaction between GDI and Cdc42. First, the amino-terminal regulatory arm of the GDI binds to the switch I and II domains of Cdc42 leading to the ...

Functional analysis of the interaction between the small GTP binding protein Cdc42 and the Ste20 protein kinase in yeast. [PDF]
STE20 encodes a protein kinase related to mammalian p65Pak which functions in several signal transduction pathways in yeast, including those involved in pseudohyphal and invasive growth, as well as mating. In addition, Ste20 plays an essential role in cells lacking Cla4, a kinase with significant homology to Ste20.

The Arp2/3 complex mediates actin polymerization induced by the small GTP-binding protein Cdc42 [PDF]
The small GTP-binding protein Cdc42 is thought to induce filopodium formation by regulating actin polymerization at the cell cortex. Although several Cdc42-binding proteins have been identified and some of them have been implicated in filopodium formation, the precise role of Cdc42 in modulating actin polymerization has not been defined ...

Atypical Protein Kinases Cλ and -ζ Associate with the GTP-Binding Protein Cdc42 and Mediate Stress Fiber Loss [PDF]
Both the Rho family of low-molecular-weight GTP-binding proteins and protein kinases C (PKCs) mediate responses to a variety of extracellular and intracellular signals. They share many downstream targets, including remodeling of the actin cytoskeleton, activation of p70(S6) kinase and c-jun N-terminal kinase (JNK), and regulation of transcription and ...

The small GTP-binding protein Cdc42 is required for nerve growth factor withdrawal-induced neuronal death [PDF]
An increase in the level of the c-Jun transcription factor and of its phosphorylation has previously been shown to be essential for nerve growth factor (NGF) withdrawal-induced apoptosis of rat sympathetic neurons (SCG). The Rho-like GTPases Cdc42 and Rac1 are involved in the regulation of a number of cellular processes, including ...

Molecular cloning of the gene for the human placental GTP-binding protein Gp (G25K): identification of this GTP-binding protein as the human homolog of the yeast cell-division-cycle protein CDC42. [PDF]
We have isolated cDNA clones from a human placental library that code for a low molecular weight GTP-binding protein originally designated Gp (also called G25K). This identification is based on comparisons with the available peptide sequences for the purified human Gp protein and the use of two highly specific anti-peptide antibodies.

Corequirement of Specific Phosphoinositides and Small GTP-binding Protein Cdc42 in Inducing Actin Assembly in Xenopus Egg Extracts [PDF]
Both phosphoinositides and small GTP-binding proteins of the Rho family have been postulated to regulate actin assembly in cells. We have reconstituted actin assembly in response to these signals in Xenopus extracts and examined the relationship of these pathways. We have found that GTPγS stimulates actin assembly in the presence of endogenous membrane
