FEBS Letters, EarlyView.LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Co-crystalization reveals the interaction between AtYchF1 and ppGpp
Frontiers in Molecular Biosciences, 2022 AtYchF1 is an unconventional G-protein in Arabidopsis thaliana that exhibits relaxed nucleotide-binding specificity. The bindings between AtYchF1 and biomolecules including GTP, ATP, and 26S rRNA have been reported.

A process model of Rho GTP-binding proteins
Theoretical Computer Science, 2009 AbstractRho GTP-binding proteins play a key role as molecular switches in many cellular activities. In response to extracellular stimuli and with the help of regulators (GEF, GAP, Effector, GDI), these proteins serve as switches that interact with their environment in a complex manner.

The GTP binding proteins Gem and Rad are negative regulators of the Rho–Rho kinase pathway
Journal of Cell Biology, 2002 The cytoskeletal changes that alter cellular morphogenesis and motility depend upon a complex interplay among molecules that regulate actin, myosin, and other cytoskeletal components.

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Small GTPase Ran and Ran-binding proteins
Biomolecular Concepts, 2012 Like many other small GTPases, Ran functions in eukaryotic cells as a molecular switch that cycles between GTP- and GDP-bound forms. Through the proper modulation of the GTP/GDP cycle, Ran functions with a number of Ran-binding proteins to control a ...

Kinetics and Thermodynamics of Membrane Protein Folding [PDF]
Biomolecules 2014, 4(1), 354-373, 2014 Understanding protein folding has been one of the great challenges in biochemistry and molecular biophysics. Over the past 50 years, many thermodynamic and kinetic studies have been performed addressing the stability of globular proteins. In comparison, advances in the membrane protein folding field lag far behind. Although membrane proteins constitute

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]
, 2002 Toc34 is a protein of the chloroplast outer envelope membrane that acts as receptor for preproteins containing a transit sequence. The recognition of preproteins by Toc34 is regulated by GTP binding and phosphorylation.
