Rho Family GTPases in Fission Yeast Cytokinesis
Communicative & Integrative Biology, 2019 During cytokinesis, actomyosin ring constriction drives furrow formation. In animal cells, Rho GTPases drive this process through the positioning and assembly of the actomyosin ring, and through extracellular matrix remodeling within the furrow.

Computational model explains high activity and rapid cycling of Rho GTPases within protein complexes. [PDF]
PLoS Computational Biology, 2006 Formation of multiprotein complexes on cellular membranes is critically dependent on the cyclic activation of small GTPases. FRAP-based analyses demonstrate that within protein complexes, some small GTPases cycle nearly three orders of magnitude faster ...

Fixing the GAP: The role of RhoGAPs in cancer
European Journal of Cell Biology, 2022 Cancer progression and metastasis are processes that involve significant cellular changes. Many of these changes include alterations in the activity of the Rho GTPase family of proteins.

Turing instabilities in a mathematical model for signaling networks
, 2011 GTPase molecules are important regulators in cells that continuously run through an activation/deactivation and membrane-attachment/membrane-detachment cycle. Activated GTPase is able to localize in parts of the membranes and to induce cell polarity.

Atypical Rho GTPases of the RhoBTB Subfamily: Roles in vesicle trafficking and tumorigenesis [PDF]
, 2016 RhoBTB proteins constitute a subfamily of atypical Rho GTPases represented in mammals by RhoBTB1, RhoBTB2, and RhoBTB3. Their characteristic feature is a carboxyl terminal extension that harbors two BTB domains capable of assembling cullin 3-dependent ...

Structure and function of bacterial dynamin-like proteins [PDF]
, 2012 Membrane dynamics are essential for numerous cellular processes in eukaryotic and prokaryotic cells. In eukaryotic cells, membrane fusion and fission are often catalyzed by large GTPases of the dynamin protein family. These proteins couple GTP hydrolysis

Drugging the Small GTPase Pathways in Cancer Treatment: Promises and Challenges
Cells, 2019 Small GTPases are a family of low molecular weight GTP-hydrolyzing enzymes that cycle between an inactive state when bound to GDP and an active state when associated to GTP.
