Proapoptotic and antiinvasive activity of Rac1 small molecule inhibitors on malignant glioma cells [PDF]
Malignant gliomas are characterized by an intrinsic ability to invade diffusely throughout the normal brain tissue. This feature contributes mainly to the failure of existing therapies. Deregulation of small GTPases signaling, in particular Rac1 activity,

Multisite phosphorylation of the guanine nucleotide exchange factor Cdc24 during yeast cell polarization. [PDF]
BACKGROUND:Cell polarization is essential for processes such as cell migration and asymmetric cell division. A common regulator of cell polarization in most eukaryotic cells is the conserved Rho GTPase, Cdc42.

Dietary Methionine Restriction Regulates Liver Protein Synthesis and Gene Expression Independently of Eukaryotic Initiation Factor 2 Phosphorylation in Mice [PDF]
Background: The phosphorylation of eukaryotic initiation factor 2 (p-eIF2) during dietary amino acid insufficiency reduces protein synthesis and alters gene expression via the integrated stress response (ISR).Objective: We explored whether a Met ...

Small GTP-binding protein Rho-mediated signaling promotes proliferation of rheumatoid synovial fibroblasts [PDF]
Rho is a major small GTP-binding protein that is involved in the regulation of various cell functions, including proliferation and cell migration, through activation of multiple signaling molecules in various types of cells.

Ric-8A, a Gα protein guanine nucleotide exchange factor potentiates taste receptor signaling
Taste receptors for sweet, bitter and umami tastants are G-protein coupled receptors (GPCRs). While much effort has been devoted to understanding G-protein-receptor interactions and identifying the components of the signalling cascade downstream of these

Research progress in the relationship between PREX1 gene and tumor pathogenesis [PDF]
Phosphatidylinositol-3, 4, 5-triphosphate-dependent Rac exchange factor 1 (PREX1) is a coding gene that is abnormally expressed in a variety of tumors. As a guanine nucleotide exchange factor (RacGEF) of small GTP binding protein Rac1, PREX1 gene-encoded

Membrane and Protein Interactions of the Pleckstrin Homology Domain Superfamily. [PDF]
The human genome encodes about 285 proteins that contain at least one annotated pleckstrin homology (PH) domain. As the first phosphoinositide binding module domain to be discovered, the PH domain recruits diverse protein architectures to cellular ...
