Loss of strumpellin in the melanocytic lineage impairs the WASH Complex but does not affect coat colour [PDF]
, 2016 The five-subunit WASH complex generates actin networks that participate in endocytic trafficking, migration and invasion in various cell types. Loss of one of the two subunits WASH or strumpellin in mice is lethal, but little is known about their role in

Primary fibroblasts from CSPα mutation carriers recapitulate hallmarks of the adult onset neuronal ceroid lipofuscinosis [PDF]
, 2017 Mutations in the co- chaperone protein, CSPα, cause an autosomal dominant, adult-neuronal ceroid lipofuscinosis (AD-ANCL). The current understanding of CSPα function exclusively at the synapse fails to explain the autophagy-lysosome pathway (ALP ...

Structural Basis for Rab8a Recruitment of RILPL2 via LRRK2 Phosphorylation of Switch 2 [PDF]
, 2020 Rab8a is associated with the dynamic regulation of membrane protrusions in polarized cells. Rab8a is one of several Rab GTPases that are substrates of leucine-rich repeat kinase 2 (LRRK2), a serine/threonine kinase that is linked to Parkinson's disease ...

IGF-I stimulates Rab7-RILP interaction during neuronal autophagy [PDF]
Neuroscience Letters, 2011 Restoration of autophagy represents a potential therapeutic target for neurodegenerative disorders, but factors that regulate autophagic flux are largely unknown. When deprived of trophic factors, cultured Purkinje neurons die by an autophagy associated cell death mechanism.

TRAF6 triggers Mycobacterium-infected host autophagy through Rab7 ubiquitination
Cell Death Discovery, 2023 AbstractTumor necrosis factor receptor-associated factor 6 (TRAF6) is an E3 ubiquitin ligase that is extensively involved in the autophagy process by interacting with diverse autophagy initiation and autophagosome maturation molecules. However, whether TRAF6 interacts with lysosomal proteins to regulate Mycobacterium-induced autophagy has not been ...

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.

Role for Rab7 in maturation of late autophagic vacuoles [PDF]
Journal of Cell Science, 2004 The small GTP binding protein Rab7 has a role in the late endocytic pathway and lysosome biogenesis. The role of mammalian Rab7 in autophagy is, however, unknown. We have addressed this by inhibiting Rab7 function with RNA interference and overexpression of dominant negative Rab7.

Intercompartmental communication in senescence
FEBS Open Bio, EarlyView.Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.

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 ...
