PH Domain-Arf G Protein Interactions Localize the Arf-GEF Steppke for Cleavage Furrow Regulation in Drosophila. [PDF]
PLoS ONE, 2015 The recruitment of GDP/GTP exchange factors (GEFs) to specific subcellular sites dictates where they activate small G proteins for the regulation of various cellular processes.

Turning Platelets Off and On: Role of RhoGAPs and RhoGEFs in Platelet Activity
Frontiers in Cardiovascular Medicine, 2022 Platelet cytoskeletal reorganisation is a critical component of platelet activation and thrombus formation in haemostasis. The Rho GTPases RhoA, Rac1 and Cdc42 are the primary drivers in the dynamic reorganisation process, leading to the development of ...

GTP Binding Assays in Arabidopsis thaliana
Bio-Protocol, 2013 Signaling through G proteins constitutes an ancient mechanism that functions in the transduction of extracellular signals into intracellular responses. Activation of a proper receptor by a stimuli leads to an exchange of GDP for GTP, the activation of G ...

GTP-binding-defective ARL4D alters mitochondrial morphology and membrane potential. [PDF]
PLoS ONE, 2012 ARL4D, ARL4A, and ARL4C are closely related members of the ADP-ribosylation factor/ARF-like protein (ARF/ARL) family of GTPases. All three ARL4 proteins contain nuclear localization signals (NLSs) at their C-termini and are primarily found at the plasma ...

Yeast Irc6p is a novel type of conserved clathrin coat accessory factor related to small G proteins. [PDF]
, 2012 Clathrin coat accessory proteins play key roles in transport mediated by clathrin-coated vesicles. Yeast Irc6p and the related mammalian p34 are putative clathrin accessory proteins that interact with clathrin adaptor complexes.

LRRK2 kinase activity is dependent on LRRK2 GTP binding capacity but independent of LRRK2 GTP binding. [PDF]
PLoS ONE, 2011 Leucine rich repeat kinase 2 (LRRK2) is a Parkinson's disease (PD) gene that encodes a large multidomain protein including both a GTPase and a kinase domain.

Involvement of a small GTP binding protein in HIV-1 release
Retrovirology, 2005 Background There is evidence suggesting that actin binding to HIV-1 encoded proteins, or even actin dynamics themselves, might play a key role in virus budding and/or release from the infected cell.

Identifying conformational changes with site-directed spin labeling reveals that the GTPase domain of HydF is a molecular switch [PDF]
, 2017 [FeFe]-hydrogenases catalyse the reduction of protons to hydrogen at a complex 2Fe[4Fe4S] center called H-cluster. The assembly of this active site is a multistep process involving three proteins, HydE, HydF and HydG.

Essential Role of the G-Domain in Targeting of the Protein Import Receptor atToc159 to the Chloroplast Outer Membrane [PDF]
, 2002 Two homologous GTP-bindin proteins, atToc33 and atToc159, control access of cytosolic precursor proteins to the chloroplast, at Toc33 is a constitutive outer chloroplast membrane protein, whereas the precusor receptor atToc159 may be able to switch ...
