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 ...

Interaction of recombinant rho A GTP‐binding proteins with photoexcited rhodopsin [PDF]
The small molecular mass GTP‐binding proteins rho A, B and C are targets for ADP‐ribosyltransferase activity of the botulinum exoenzyme C3. The possible interaction of recombinant rho A proteins expressed in E. coli with photoexcited rhodopsin was studied by reconstitution with bovine rod outer segment (ROS) membranes depleted of endogenous GTP‐binding

Direct Involvement of the Small GTP-binding Protein Rho in lbc Oncogene Function [PDF]
The lbc oncogene is tumorigenic in nude mice, transforms NIH 3T3 fibroblasts, and encodes a Dbl homology domain found in several transforming gene products including the dbl oncogene product. While both lbc- and dbl-transformed NIH 3T3 foci exhibited a comparable gross appearance, lbc-transformed cell morphology was clearly distinct from that of dbl ...

Toxin-induced activation of Rho GTP-binding protein increases Bcl-2 expression and influences mitochondrial homeostasis. [PDF]
It is now well established that apoptosis plays a pivotal role in several physiological and pathological situations. Consequently, the mechanisms controlling the cell fate are currently the subject of intense investigation.

Turning Platelets Off and On: Role of RhoGAPs and RhoGEFs in Platelet Activity
Platelet cytoskeletal reorganisation is a critical component of platelet activation and thrombus formation in haemostasis. The Rho GTPases RhoA, Rac1 and Cdc42 are the primary drivers in the dynamic reorganisation process, leading to the development of ...

Rho GTPases as Key Molecular Players within Intestinal Mucosa and GI Diseases
Rho proteins operate as key regulators of the cytoskeleton, cell morphology and trafficking. Acting as molecular switches, the function of Rho GTPases is determined by guanosine triphosphate (GTP)/guanosine diphosphate (GDP) exchange and their lipidation

Thrombopoietin and collagen in low doses cooperatively induce human platelet activation
Aim In acute medicine, we occasionally treat life‐threatening conditions such as sepsis and trauma, which cause severe thrombocytopenia. Serum thrombopoietin levels have been reported to increase under the condition of thrombocytopenia related to ...

Identification of potential small molecule binding pockets on Rho family GTPases. [PDF]
Rho GTPases are conformational switches that control a wide variety of signaling pathways critical for eukaryotic cell development and proliferation. They represent attractive targets for drug design as their aberrant function and deregulated activity is
