Current Protocols, 2023 Abstract In different cellular activities like signal transduction, cell division, and intracellular transportation, small GTPases take on a vital role. Their functioning involves hydrolysing guanosine triphosphate (GTP) to guanosine diphosphate (GDP). In this article we explain the application of a commercially accessible GTPase assay,

WormBook, 2018 Members of the protein superfamily of small guanosine triphosphatases, also known as small GTPases, small G-proteins, or the Ras superfamily, are involved in nearly every aspect of cell biology. Small GTPases are tightly regulated molecular switches that make binary on/off decisions through controlled loading of GTP (activation) and hydrolysis of GTP ...

Miro GTPase domains regulate the assembly of the mitochondrial motor–adaptor complex
Life Science Alliance, 2023 Relocalizing the mitochondrial motor–adaptor protein Miro to peroxisomes and systematically manipulating each GTPase domain reveal the importance of the N-terminal GTPase domain of Miro1 for regulating mitochondrial transport.

A mechanism for the response of KRASG13D expressing colorectal cancers to EGFR inhibitors
Molecular & Cellular Oncology, 2020 Previous analysis of Phase 3 clinical trial data for colorectal cancer patients treated with cetuximab revealed that patients harboring a KRAS mutation did not benefit from treatment.

The Impact of the Stringent Response on TRAFAC GTPases and Prokaryotic Ribosome Assembly
Cells, 2019 Many facets of ribosome biogenesis and function, including ribosomal RNA (rRNA) transcription, 70S assembly and protein translation, are negatively impacted upon induction of a nutrient stress-sensing signalling pathway termed the stringent response ...

A highly-sensitive high throughput assay for dynamin's basal GTPase activity. [PDF]
PLoS ONE, 2017 Clathrin-mediated endocytosis is the major pathway by which cells internalize materials from the external environment. Dynamin, a large multidomain GTPase, is a key regulator of clathrin-mediated endocytosis.

WormBook, 2006 Small GTPases of the Ras superfamily are key regulators of diverse cellular and developmental events, including differentiation, cell division, vesicle transport, nuclear assembly, and control of the cytoskeleton. The C. elegans genome encodes 56 members of the major Ras GTPase subfamilies, including the Ras/Ral/Rap family, the Rho family, the Rab ...

The roles of GTPase-activating proteins in regulated cell death and tumor immunity
Journal of Hematology & Oncology, 2021 GTPase-activating protein (GAP) is a negative regulator of GTPase protein that is thought to promote the conversion of the active GTPase-GTP form to the GTPase-GDP form.
