Novel split-luciferase-based genetically encoded biosensors for noninvasive visualization of Rho GTPases. [PDF]

PLoS ONE, 2013
Rho family GTPases are critical regulators of many important cellular processes and the dysregulation of their activities is implicated in a variety of human diseases including oncogenesis and propagation of malignancy.

Regulation of polarised growth in fungi [PDF]

, 2008
Polarised growth in fungi occurs through the delivery of secretory vesicles along tracks formed by cytoskeletal elements to specific sites on the cell surface where they dock with a multiprotein structure called the exocyst before fusing with the ...

Regulation of the small GTP-binding protein Rho by cell adhesion and the cytoskeleton [PDF]

The EMBO Journal, 1999
Soluble factors from serum such as lysophosphatidic acid (LPA) are thought to activate the small GTP-binding protein Rho based on their ability to induce actin stress fibers and focal adhesions in a Rho-dependent manner. Cell adhesion to extracellular matrices (ECM) has also been proposed to activate Rho, but this point has been controversial due to ...

High throughput transcriptome profiling of lithium stimulated human mesenchymal stem cells reveals priming towards osteoblastic lineage. [PDF]

PLoS ONE, 2013
Human mesenchymal stem cells (hMSCs) present in the bone marrow are the precursors of osteoblasts, chondrocytes and adipocytes, and hold tremendous potential for osteoregenerative therapy.

Nitric Oxide Mediates Biofilm Formation and Symbiosis in Silicibacter sp. Strain TrichCH4B. [PDF]

, 2015
UnlabelledNitric oxide (NO) plays an important signaling role in all domains of life. Many bacteria contain a heme-nitric oxide/oxygen binding (H-NOX) protein that selectively binds NO.

Actin re-organization induced by Chlamydia trachomatis serovar D--evidence for a critical role of the effector protein CT166 targeting Rac. [PDF]

PLoS ONE, 2010
The intracellular bacterium Chlamydia trachomatis causes infections of urogenital tract, eyes or lungs. Alignment reveals homology of CT166, a putative effector protein of urogenital C. trachomatis serovars, with the N-terminal glucosyltransferase domain

The domain architecture of large guanine nucleotide exchange factors for the small GTP-binding protein Arf

BMC Genomics, 2005
BackgroundSmall G proteins, which are essential regulators of multiple cellular functions, are activated by guanine nucleotide exchange factors (GEFs) that stimulate the exchange of the tightly bound GDP nucleotide by GTP.

Phytochrome regulates GTP‐binding protein activity in the envelope of pea nuclei [PDF]

The Plant Journal, 1993
Three GTP‐binding proteins with apparent molecular masses of 27, 28 and 30 kDa have been detected in isolated nuclei of etiolated pea plumules. After LDS‐PAGE and transfer to nitrocellulose these proteins bind [32p]GTP in the presence of excess ATP, suggesting that they are monomeric G proteins.

Phosphatidylinositol (4,5)-bisphosphate turnover by INP51 regulates the cell wall integrity pathway in "Saccharomyces cerevisiae" [PDF]

, 2004
Signal transduction pathways are important for the cell to transduce external or internal stimuli where second messengers play an important role as mediators of the stimuli. One important group of second messengers are the phosphoinositide family present
