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 ...

Ribosome-associated GTPases: The role of RNA for GTPase activation [PDF]
RNA Biology, 2010 The GTPase super-family comprises a variety of G proteins found in all three domains of life. Although they are participating in completely different processes like signal transduction, protein biosynthesis and regulation of cell proliferation, they all share a highly conserved G domain and use a common mechanism for GTP hydrolysis.

NF-κB signaling and crosstalk during carcinogenesis
4 open, 2019 Transcription factors (TFs) are proteins that control the transcription of genetic information from DNA to mRNA by binding to specific DNA sequences either on their own or with other proteins as a complex.

A Rho family GTPase controls actin dynamics and tip growth via two counteracting downstream pathways in pollen tubes. [PDF]
, 2005 Tip growth in neuronal cells, plant cells, and fungal hyphae is known to require tip-localized Rho GTPase, calcium, and filamentous actin (F-actin), but how they interact with each other is unclear.

Domain interactions within Fzo1 oligomers are essential for mitochondrial fusion [PDF]
, 2006 Mitofusins are conserved GTPases essential for the fusion of mitochondria. These mitochondrial outer membrane proteins contain a GTPase domain and two or three regions with hydrophobic heptad repeats, but little is known about how these domains interact ...

Journal of Biomedical Science, 2007 Chloroplasts import more than 90% of their protein constituents from the cytosol. The import is mediated by translocon complexes located in the chloroplast envelope and the stroma. This review focuses on the two GTPases in the Toc (translocon at the outer envelope membrane of chloroplasts) complex. Hypotheses are presented about gating across the outer

Small GTPase Rab3B: biological properties and possible role in carcinogenesis
Успехи молекулярной онкологии, 2019 Proteins of the superfamily of small guanosine triphosphate hydrolase (GTPase) perform various functions: from the control of cell proliferation to the regulation of vesicular transport. The superfamily of small GTPase Ras includes more than 150 proteins,

GTPase activity and neuronal toxicity of Parkinson's disease-associated LRRK2 is regulated by ArfGAP1. [PDF]
PLoS Genetics, 2012 Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are the most common cause of autosomal dominant familial Parkinson's disease (PD) and also contribute to idiopathic PD. LRRK2 encodes a large multi-domain protein with GTPase and kinase activity.
