Efficient Interaction between Two GTPases Allows the Chloroplast SRP Pathway to Bypass the Requirement for an SRP RNA [PDF]
, 2007 Cotranslational protein targeting to membranes is regulated by two GTPases in the signal recognition particle (SRP) and the SRP receptor; association between the two GTPases is slow and is accelerated 400-fold by the SRP RNA.

Journal of Cell Science, 2007 Rab GTPases control vesicle movement and tethering membrane events in membrane trafficking. We used the 38 human Rab GTPase activating proteins (GAPs) to identify which of the 60 Rabs encoded in the human genome function at the Golgi 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.

The role of Cdc42p GTPase-activating proteins in assembly of the septin ring in yeast.
Molecular Biology of the Cell, 2003 The septins are a conserved family of GTP-binding, filament-forming proteins. In the yeast Saccharomyces cerevisiae, the septins form a ring at the mother-bud neck that appears to function primarily by serving as a scaffold for the recruitment of other ...

The gateway to chloroplast: re-defining the function of chloroplast receptor proteins [PDF]
, 2012 Chloroplast biogenesis often requires a tight orchestration between gene expression (both plastidial and nuclear) and translocation of similar to 3000 nuclear-encoded proteins into the organelle.

Regulation of ras p21 by GTPase Activating Proteins
Cold Spring Harbor Symposia on Quantitative Biology, 1991 We propose a model for dual effector functions of the known ras GAPs p120-GAP and NF1-GAP. This model is consistent with known biological and biochemical effects of GAPs in mammalian cells, but it is clearly not a proven hypothesis, and several difficulties remain in making this model convincing.

The yeast Rgd1p is a GTPase activating protein of the Rho3 and Rho4 proteins [PDF]
FEBS Letters, 1999 The RGD1 gene, identified during sequencing of the Saccharomyces cerevisiae genome, encodes a protein with a Rho‐GTPase activating protein (GAP) domain at the carboxy‐terminal end. The Rgd1 protein showed two‐hybrid interactions with the activated forms of Rho2p, Rho3p and Rho4p.

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 ...
