The Role of Mg2+ Cofactor in the Guanine Nucleotide Exchange and GTP Hydrolysis Reactions of Rho Family GTP-binding Proteins*

open access: yesJournal of Biological Chemistry, 2000
The biological activities of Rho family GTPases are controlled by their guanine nucleotide binding states in cells. Here we have investigated the role of Mg2+ cofactor in the guanine nucleotide binding and hydrolysis processes of the Rho family members ...

Signal transduction gRABs attention [PDF]

open access: yes, 2006
Rab proteins are small GTPases involved in the regulation of vesicular membrane traffic. Research done in the past years has demonstrated that some of these proteins are under the control of signal transduction pathways.

Atypical Rho GTPases of the RhoBTB Subfamily: Roles in vesicle trafficking and tumorigenesis [PDF]

open access: yes, 2016
RhoBTB proteins constitute a subfamily of atypical Rho GTPases represented in mammals by RhoBTB1, RhoBTB2, and RhoBTB3. Their characteristic feature is a carboxyl terminal extension that harbors two BTB domains capable of assembling cullin 3-dependent ...

Identification and Characterisation of the RalA-ERp57 Interaction: Evidence for GDI Activity of ERp57 [PDF]

open access: yes, 2012
RalA is a membrane-associated small GTPase that regulates vesicle trafficking. Here we identify a specific interaction between RalA and ERp57, an oxidoreductase and signalling protein.

Rab7a and Mitophagosome Formation

open access: yesCells, 2019
The small GTPase, Rab7a, and the regulators of its GDP/GTP-binding status were shown to have roles in both endocytic membrane traffic and autophagy. Classically known to regulate endosomal retrograde transport and late endosome-lysosome fusion, earlier ...

Molecular Aspects of Secretory Granule Exocytosis by Neurons and Endocrine Cells [PDF]

open access: yes, 1994
Neuronal communication and endocrine signaling are fundamental for integrating the function of tissues and cells in the body. Hormones released by endocrine cells are transported to the target cells through the circulation.

Sbf/MTMR13 coordinates PI(3)P and Rab21 regulation in endocytic control of cellular remodeling. [PDF]

open access: yes, 2012
Cells rely on the coordinated regulation of lipid phosphoinositides and Rab GTPases to define membrane compartment fates along distinct trafficking routes.

The chloroplast import receptor Toc34 functions as preprotein-regulated GTPase [PDF]

open access: yes, 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.

Rab29 activation of the Parkinson's disease-associated LRRK2 kinase [PDF]

open access: yes, 2017
Parkinson's disease predisposing LRRK2 kinase phosphorylates a group of Rab GTPase proteins including Rab29, within the effector‐binding switch II motif. Previous work indicated that Rab29, located within the PARK16 locus mutated in Parkinson's patients,
