A conserved and regulated mechanism drives endosomal Rab transition

open access: yeseLife, 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,

Differences in endosomal Rab gene expression between positive and negative COVID-19 patients

open access: yesBMC Research Notes, 2022
Objective SARS CoV-2, the etiologic agent of coronavirus disease-2019 (COVID-19) is well-known to use ACE2 to begin internalization. Some viruses enter the host cell through the endocytosis process and involve some endocytosis proteins, such as the Rab ...

Rab7 associates with early endosomes to mediate sorting and transport of Semliki forest virus to late endosomes. [PDF]

open access: yesPLoS Biology, 2005
Semliki forest virus (SFV) is internalized by clathrin-mediated endocytosis, and transported via early endosomes to late endosomes and lysosomes. The intracellular pathway taken by individual fluorescently labeled SFV particles was followed using ...

Mechanism by which Rab5 promotes regeneration and functional recovery of zebrafish Mauthner axons

open access: yesNeural Regeneration Research
Rab5 is a GTPase protein that is involved in intracellular membrane trafficking. It functions by binding to various effector proteins and regulating cellular responses, including the formation of transport vesicles and their fusion with the cellular ...

Tropheryma whipplei, the agent of Whipple's disease, affects the early to late phagosome transition and survives in a Rab5- and Rab7-positive compartment.

open access: yesPLoS ONE, 2014
Tropheryma whipplei, the agent of Whipple's disease, inhibits phago-lysosome biogenesis to create a suitable niche for its survival and replication in macrophages. To understand the mechanism by which it subverts phagosome maturation, we used biochemical

Inhibition of endosome fusion by wortmannin persists in the presence of activated Rab5 [PDF]

open access: yes, 1998
Rab5-dependent endosome fusion is sensitive to the phosphoinositide 3-kinase inhibitor, wortmannin. It has been proposed that phosphoinositide 3-kinase activity may be required for activation of rab5 by influencing its nucleotide cycle such as to promote

Rab21 recruits EEA1 and competes with Rab5 for Rabex-5 activation

open access: yesFrontiers in Cell and Developmental Biology
Rab5 is a key regulator of early endosomal traffic and fusion. It shares its localization and guanine nucleotide exchange factor Rabex-5 with the less characterized member of the Rab5 subfamily Rab21.

Direct binding of vinculin and Rab5.

open access: yes, 2014
(A) Endogenous vinculin and Rab5 were immunoprecipitated from Cos-7 lysates with anti-Rab5 or anti-vinculin antibodies. Vinculin and Rab5 were assayed by western blotting using specific antibodies to vinculin and Rab5.

Evidence for a symmetrical requirement for Rab5-GTP in in vitro endosome-endosome fusion

open access: yes, 1998
Early endosome fusion, which has been extensively characterized using an in vitro reconstitution assay, is Rab5-dependent. To examine the requirement for Rab5 on both fusion partners, we prepared cytosol and endosomes depleted of Rab5.

Rab5 Association with the Angiotensin II Type 1A Receptor Promotes Rab5 GTP Binding and Vesicular Fusion [PDF]

open access: yesJournal of Biological Chemistry, 2002
Previous studies have demonstrated that the internalization of the angiotensin II type 1A receptor (AT(1A)R) may be mediated by both beta-arrestin-sensitive and -insensitive mechanisms. Therefore, we have used the AT(1A)R carboxyl-terminal tail to screen a rat brain yeast two-hybrid expression library for novel AT(1A)R-interacting proteins that might ...
