Critical role for Piccolo in synaptic vesicle retrieval

eLife, 2019
Loss of function of the active zone protein Piccolo has recently been linked to a disease, Pontocerebellar Hypoplasia type 3, which causes brain atrophy.

Turing instabilities in a mathematical model for signaling networks

, 2011
GTPase molecules are important regulators in cells that continuously run through an activation/deactivation and membrane-attachment/membrane-detachment cycle. Activated GTPase is able to localize in parts of the membranes and to induce cell polarity.

A C3(H20) recycling pathway is a component of the intracellular complement system [PDF]

, 2017
An intracellular complement system (ICS) has recently been described in immune and nonimmune human cells. This system can be activated in a convertase-independent manner from intracellular stores of the complement component C3. The source of these stores

Signal transduction gRABs attention [PDF]

, 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.

Regulation of Liver Metabolism by the Endosomal GTPase Rab5

Cell Reports, 2015
The liver maintains glucose and lipid homeostasis by adapting its metabolic activity to the energy needs of the organism. Communication between hepatocytes and extracellular environment via endocytosis is key to such homeostasis. Here, we addressed the question of whether endosomes are required for gluconeogenic gene expression.

Coordination between ESCRT function and Rab conversion during endosome maturation

The EMBO Journal
The endosomal pathway is essential for regulating cell signaling and cellular homeostasis. Rab5 positive early endosomes receive proteins from the plasma membrane.

Molecular mechanism for Rabex-5 GEF activation by Rabaptin-5

eLife, 2014
Rabex-5 and Rabaptin-5 function together to activate Rab5 and further promote early endosomal fusion in endocytosis. The Rabex-5 GEF activity is autoinhibited by the Rabex-5 CC domain (Rabex-5CC) and activated by the Rabaptin-5 C2-1 domain (Rabaptin-5C21)

Changes in early endosomes in rat hippocampal CA1 neurons after transient global cerebral ischaemia

Folia Histochemica et Cytobiologica
INTRODUCTION: Transient global ischaemia in rodents causes selective loss of hippocampal CA1neurons, but the potential involvement of endocytic pathways has not been fully explored.

Rabex-5 E3 and Rab5 GEF domains differ in their regulation of Ras, Notch, and PI3K signaling in Drosophila wing development.

PLoS ONE
Rabex-5 (also called RabGEF1), a protein originally characterized for its Rab5 GEF function, also has an A20-like E3 ubiquitin ligase domain. We and others reported that Rabex-5 E3 activity promotes Ras mono- and di-ubiquitination to inhibit Ras ...
