SPIN90, an adaptor protein, alters the proximity between Rab5 and Gapex5 and facilitates Rab5 activation during EGF endocytosis [PDF]

Experimental and Molecular Medicine, 2019
Intracellular transport: a new SPIN A key protein required for incorporating substances into cells has been identified by researchers in South Korea. During this process, called endocytosis, materials are engulfed by the cell membrane, then packaged into

rab5 GTPase Regulates Adenovirus Endocytosis [PDF]

Journal of Virology, 1999
ABSTRACT Adenovirus interaction with αv integrins is important for virus entry. We have examined the effects of adenovirus attachment on intracellular signaling in HeLa cells, with an emphasis on pathways known to be activated following integrin interaction with other ligands. We found no evidence for [Ca 2+

Assessing Rab5 Activation in Health and Disease [PDF]

, 2021
The endocytic pathway is a system of dynamically communicating vesicles, known as early endosomes, that internalize, sort, and traffic nutrients, trophic factors, and signaling molecules to sites throughout the cell. In all eukaryotic cells, early endosome functions are regulated by Rab5 activity, dependent upon its binding to GTP, whereas Rab5 bound ...

Rab5-dependent autophagosome closure by ESCRT [PDF]

Journal of Cell Biology, 2019
In the conserved autophagy pathway, autophagosomes (APs) engulf cellular components and deliver them to the lysosome for degradation. Before fusing with the lysosome, APs have to close via an unknown mechanism. We have previously shown that the endocytic Rab5-GTPase regulates AP closure.

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

Journal 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 ...

Mendelian randomization analysis identifies HLA-A and AP2M1 as genetic biomarkers linked to immune-endocytic crosstalk in intervertebral disc degeneration. [PDF]

J Cell Commun Signal
HLA‐A and AP2M1 are identified as key endocytosis‐related biomarkers that modulate immune–endocytic crosstalk via mTOR signaling to regulate cell survival, immune infiltration, and the progression of intervertebral disc degeneration. Abstract Intervertebral disc degeneration (IVDD) is a major contributor to chronic spinal disorders, yet the role of ...

Identification of the Rab5 Binding Site in p110β: Assays for PI3Kβ Binding to Rab5 [PDF]

, 2015
Isoform-specific signaling by Class IA PI 3-kinases depends in part on the interactions between distinct catalytic subunits and upstream regulatory proteins. From among the class IA catalytic subunits (p110α, p110β, and p110δ), p110β has unique properties.

A non-linear system patterns Rab5 GTPase on the membrane

eLife, 2020
Proteins can self-organize into spatial patterns via non-linear dynamic interactions on cellular membranes. Modelling and simulations have shown that small GTPases can generate patterns by coupling guanine nucleotide exchange factors (GEF) to effectors ...

The plant-pathogen haustorial interface at a glance [PDF]

, 2020
Many filamentous pathogens invade plant cells through specialized hyphae called haustoria. These infection structures are enveloped by a newly synthesized plant-derived membrane called the extrahaustorial membrane (EHM).

The ubiquitous dermokine delta activates Rab5 function in the early endocytic pathway. [PDF]

PLoS ONE, 2011
The expression of the recently identified dermokine (Dmkn) gene leads to four families of proteins with as yet unknown functions. The secreted α, β and γ isoforms share an epidermis-restricted expression pattern, whereas the δ isoform is intracellular ...
