Rab7 mutants associated with Charcot-Marie-Tooth disease exhibit enhanced NGF-stimulated signaling. [PDF]
PLoS ONE, 2010 Missense mutants in the late endosomal Rab7 GTPase cause the autosomal dominant peripheral neuropathy Charcot-Marie-Tooth disease type 2B (CMT2B). As yet, the pathological mechanisms connecting mutant Rab7 protein expression to altered neuronal function ...

Protocol for quantifying miRNA trafficking across the endosomal membrane
FEBS Open Bio, EarlyView.An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

requires Rab7-mediated degradation of endocytosed hemoglobin for their growth
, 2008 Leishmania is unable to synthesize heme and must acquire it from exogenous source, the mechanism of which is not known. We have shown that Leishmania endocytoses hemoglobin (Hb) and subsequently degrade it probably to generate heme.

Autophagy, 2020 NRBF2 is a component of the class III phosphatidylinositol 3-kinase (PtdIns3K) complex. Our previous study has revealed its role in regulating ATG14-associated PtdIns3K activity for autophagosome initiation. In this study, we revealed an unknown mechanism by which NRBF2 modulates autophagosome maturation and APP-C-terminal fragment (CTF) degradation ...

eLife, 2013 The small GTPase Rab7 is a key regulator of endosomal maturation in eukaryotic cells. Mutations in rab7 are thought to cause the dominant neuropathy Charcot-Marie-Tooth 2B (CMT2B) by a gain-of-function mechanism.

Rab1A Promotes Hepatic Steatosis by Suppressing Mitophagy via the Raf‐1/ERK1/2/PINK1 Signaling Axis
Advanced Science, EarlyView.Why does fat accumulate in the liver? Our study reveals Rab1A as the molecular switch that silences the cell's mitochondrial cleanup crew. Turning Rab1A off reactivates mitophagy, clears excess fat, and reverses fatty liver disease in mice—offering a promising new therapeutic target for MASLD, a growing global health challenge.

Advanced Science, EarlyView.Amphiphilic sulfonated chitosan nanoparticles buffer endo/lysosomal acidity in microglia by limiting V‐ATPase membrane recruitment and restoring endosomal homeostasis. Following systemic administration, they accumulate in the ischemic hemisphere partly through association with infiltrating immune cells, suppress TLR3/IRF3 and TLR4/NF‐κB signaling ...

Mechanistic and Functional Studies of Rab7 Phosphorylation [PDF]
, 2016 Rab7调控着从内体到溶酶体以及从内体到高尔基体的囊泡运输过程；也参与了自噬、吞噬过程；同时还调节着溶酶体及其相关细胞器的生成过程。Rab7的功能受到各种相互作用因子的调控；Rab7的功能异常会导致包括神经退行性疾病和肿瘤在内的多种疾病。前期实验发现Rab7与Src在早期内体和晚期内体共定位，另有报道v-Src可激活Rab7，但是Src对Rab7的调节机制尚不清楚。 本研究发现Src、Blk等酪氨酸激酶可磷酸化修饰Rab7，其磷酸化位点为第183位酪氨酸残基 ...
