Nucleotide binding switches the information flow in ras GTPases.
PLoS Computational Biology, 2011 The Ras superfamily comprises many guanine nucleotide-binding proteins (G proteins) that are essential to intracellular signal transduction. The guanine nucleotide-dependent intrinsic flexibility patterns of five G proteins were investigated in atomic ...

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

Studying GGDEF Domain in the Act: Minimize Conformational Frustration to Prevent Artefacts
Life, 2021 GGDEF-containing proteins respond to different environmental cues to finely modulate cyclic diguanylate (c-di-GMP) levels in time and space, making the allosteric control a distinctive trait of the corresponding proteins.

This Is the End: Regulation of Rab7 Nucleotide Binding in Endolysosomal Trafficking and Autophagy
Frontiers in Cell and Developmental Biology, 2018 Rab7 – or in yeast, Ypt7p – governs membrane trafficking in the late endocytic and autophagic pathways. Rab7 also regulates mitochondrion-lysosome contacts, the sites of mitochondrial fission.

Rabaptin5 is recruited to endosomes by Rab4a and Rabex5 to regulate endosome maturation [PDF]
, 2014 Membrane trafficking between organelles is fundamental to the existence of eukaryotic cells. A multitude of proteins is involved in membrane trafficking, acting as building blocks for transport carriers, regulators of transport, and targeting and fusion ...

Structural Insights into How Yrb2p Accelerates the Assembly of the Xpo1p Nuclear Export Complex
Cell Reports, 2014 Proteins and ribonucleoproteins containing a nuclear export signal (NES) assemble with the exportin Xpo1p (yeast CRM1) and Gsp1p-GTP (yeast Ran-GTP) in the nucleus and exit through the nuclear pore complex.

GTP and Ca2+ Modulate the Inositol 1,4,5-Trisphosphate-Dependent Ca2+ Release in Streptolysin O-Permeabilized Bovine Adrenal Chromaffin Cells [PDF]
, 1991 The inositol 1,4,5-trisphosphate (IP3)-induced Ca2+ release was studied using streptolysin O-permeabilized bovine adrenal chromaffin cells. The IP3-induced Ca2+ release was followed by Ca2+ reuptake into intracellular compartments.
