Small GTPase patterning: How to stabilise cluster coexistence.
PLoS ONE, 2019 Many biological processes have to occur at specific locations on the cell membrane. These locations are often specified by the localised activity of small GTPase proteins.

Rho family GTPases: Key players in neuronal development, neuronal survival, and neurodegeneration
Frontiers in Cellular Neuroscience, 2014 The Rho family of GTPases belongs to the Ras superfamily of low molecular weight (~21 kDa) guanine nucleotide binding proteins. The most extensively studied members are RhoA, Rac1, and Cdc42.

A Rab10:RalA G protein cascade regulates insulin-stimulated glucose uptake in adipocytes. [PDF]
, 2014 Insulin-stimulated glucose uptake in fat and muscle is mediated by the major facilitative glucose transporter Glut4. Insulin controls the trafficking of Glut4 to the plasma membrane via regulation of a series of small G proteins, including RalA and Rab10.

Rab GTPases in Immunity and Inflammation [PDF]
Frontiers in Cellular and Infection Microbiology, 2017 Strict spatiotemporal control of trafficking events between organelles is critical for maintaining homeostasis and directing cellular responses. This regulation is particularly important in immune cells for mounting specialized immune defenses. By controlling the formation, transport and fusion of intracellular organelles, Rab GTPases serve as master ...

Emerging role of ARHGAP29 in melanoma cell phenotype switching
Molecular Oncology, EarlyView.This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

The gateway to chloroplast: re-defining the function of chloroplast receptor proteins [PDF]
, 2012 Chloroplast biogenesis often requires a tight orchestration between gene expression (both plastidial and nuclear) and translocation of similar to 3000 nuclear-encoded proteins into the organelle.

Journal of Cell Biology, 1996 Ran is a nuclear Ras-like GTPase that is required for the bidirectional transport of proteins and ribnucleoproteins across the nuclear pore complex (NPC). A key regulator of the Ran GTP/GDP cycle is the 70-kD Ran-GTPase-activating protein RanGAP1.

Imperial strategy of cancer cells through mitochondrial transfer
Molecular Oncology, EarlyView.Cangkrama et al. demonstrated that cancer cells donate their mitochondria to fibroblasts through mitochondrial transfer, reprogramming them into ‘MitoCAF’. Likewise, our group has identified mitochondrial transfer from cancer cells to tumor infiltrating lymphocytes, resulting in mitochondrial ‘hijack’ and impaired antitumor immunity.

PLoS ONE, 2014 The Deinococcus radiodurans genome encodes homologues of divisome proteins including FtsZ and FtsA. FtsZ of this bacterium (Dr-FtsZ) has been recently characterized. In this paper, we study FtsA of D.

Coordination of Rho GTPase activities during cell protrusion
Nature, 2009 The GTPases Rac1, RhoA and Cdc42 act together to control cytoskeleton dynamics. Recent biosensor studies have shown that all three GTPases are activated at the front of migrating cells, and biochemical evidence suggests that they may regulate one another:
