Activation of Rac-1 and RhoA contributes to podocyte injury in chronic kidney disease [PDF]
, 2013 Rho-family GTPases like RhoA and Rac-1 are potent regulators of cellular signaling that control gene expression, migration and inflammation. Activation of Rho-GTPases has been linked to podocyte dysfunction, a feature of chronic kidney diseases (CKD). We

Symmetry breaking in a bulk-surface reaction-diffusion model for signaling networks [PDF]
, 2013 Signaling molecules play an important role for many cellular functions. We investigate here a general system of two membrane reaction-diffusion equations coupled to a diffusion equation inside the cell by a Robin-type boundary condition and a flux term ...

Mutations in human dynamin block an intermediate stage in coated vesicle formation [PDF]
, 1993 The role of human dynamin in receptor-mediated endocytosis was investigated by transient expression of GTP-binding domain mutants in mammalian cells. Using assays which detect intermediates in coated vesicle formation, the dynamin mutants were found to ...

Small GTPases: Structure, biological function and its interaction with nanoparticles
Asian Journal of Pharmaceutical Sciences, 2019 Small GTPase is a kind of GTP-binding protein commonly found in eukaryotic cells. It plays an important role in cytoskeletal reorganization, cell polarity, cell cycle progression, gene expression and many other significant events in cells, such as the ...

ARHGEF7 (Beta-PIX) acts as guanine nucleotide exchange factor for leucine-rich repeat kinase 2. [PDF]
PLoS ONE, 2010 Mutations within the leucine-rich repeat kinase 2 (LRRK2) gene are a common cause of familial and sporadic Parkinson's disease. The multidomain protein LRRK2 exhibits overall low GTPase and kinase activity in vitro.Here, we show that the rho guanine ...

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]
, 2002 Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.

Small GTPases all over invadosomes
Small GTPases, 2021 Cell invasion is associated with numerous patho-physiologic states including cell development and metastatic dissemination. This process couples the activation of cell motility with the capacity to degrade the extracellular matrix, thereby permitting cells to pass through basal membranes. Invasion is sustained by the actions of invadosomes, an ensemble
