Cancers, 2020 The Rab GTPase family of proteins are mediators of membrane trafficking, conferring identity to the cell membranes. Recently, Rab and Rab-associated factors have been recognized as major regulators of the intracellular positioning and activity of ...

α1B-adrenergic receptors differentially associate with Rab proteins during homologous and heterologous desensitization. [PDF]
PLoS ONE, 2015 Internalization of G protein-coupled receptors can be triggered by agonists or by other stimuli. The process begins within seconds of cell activation and contributes to receptor desensitization.

Effect of vine and fruit pruning on yield attributes of two watermelon (Citrullus lanatus) cultivars
Advances in Horticultural Science, 2021 This study was carried out to determine the effect of vine and fruit pruning on watermelon (Citrullus lanatus) yield. Five pruning methods: P1=no pruning at all, P2=pruning to four vines with two fruits per vine, P3=pruning to four vines with one fruit ...

Rab GTPase localization and Rab cascades in Golgi transport [PDF]
Biochemical Society Transactions, 2012 Rab GTPases are master regulators of membrane traffic. By binding to distinct sets of effector proteins, Rabs catalyse the formation of function-specifying membrane microdomains. They are delivered to membranes by a protein named GDI (guanine-nucleotide-dissociation inhibitor) and are stabilized there after nucleotide exchange by effector binding.

Role of Rab GTPases in membrane traffic and cell physiology.
Physiological Reviews, 2011 Intracellular membrane traffic defines a complex network of pathways that connects many of the membrane-bound organelles of eukaryotic cells. Although each pathway is governed by its own set of factors, they all contain Rab GTPases that serve as master ...

, 2015 Rab proteins represent the largest branch of the Ras-like small GTPase superfamily and there are 66 Rab genes in the human genome. They alternate between GTP- and GDP-bound states, which are facilitated by guanine nucleotide exchange factors (GEFs) and GTPase-activating proteins (GAPs), and function as molecular switches in regulation of intracellular ...

Mechanism of Digeranylgeranylation of Rab Proteins [PDF]
Journal of Biological Chemistry, 1996 Rab proteins are Ras-related small GTPases that are digeranylgeranylated at carboxyl-terminal cysteines, a modification essential for their action as molecular switches regulating intracellular vesicular transport. Geranylgeranylation of Rabs is a complex reaction that requires a catalytic Rab geranylgeranyl transferase (GGTase) and a Rab escort ...

eLife, 2017 We previously reported that Parkinson’s disease (PD) kinase LRRK2 phosphorylates a subset of Rab GTPases on a conserved residue in their switch-II domains (Steger et al., 2016) (PMID: 26824392). Here, we systematically analyzed the Rab protein family and

A conserved and regulated mechanism drives endosomal Rab transition
eLife, 2020 Endosomes and lysosomes harbor Rab5 and Rab7 on their surface as key proteins involved in their identity, biogenesis, and fusion. Rab activation requires a guanine nucleotide exchange factor (GEF), which is Mon1-Ccz1 for Rab7. During endosome maturation,
