Rab7: roles in membrane trafficking and disease
The endocytosis pathway controls multiple cellular and physiological events. The lysosome is the destination of newly synthesized lysosomal hydrolytic enzymes. Internalized molecules or particles are delivered to the lysosome for degradation through sequential transport along the endocytic pathway. The endocytic pathway is also emerging as a signalling

Chronic alcohol consumption retards lipophagy, which contributes to the pathogenesis of liver steatosis. Lipophagy-related Rab7 has been presumed as a crucial regulator in the progression of alcohol liver disease despite elusive mechanisms.

Retromer is an endosomal multi-protein complex that organizes the endocytic recycling of a vast range of integral membrane proteins. Here, we establish an additional retromer function in controlling the activity and localization of the late endosomal small GTPase RAB7. Surprisingly, we found that RAB7 not only decorates late endosomes or lysosomes, but

Role of the Small GTPase RAB7 in the Late Endocytic Pathway [PDF]
Rab7 is a small GTPase localized to the late endosomal compartment. Its function was investigated by overexpressing dominant negative or constitutively active mutants in BHK-21 cells. The effects of such overexpression on the internalization and/or degradation of different endocytic markers and on the morphology of the late endosomal compartment were ...

Role for Rab7 in maturation of late autophagic vacuoles [PDF]
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.

Supporting a role for the GTPase Rab7 in prostate cancer progression. [PDF]
Invasion and subsequent metastasis is the major cause of death from most cancers including prostate cancer. Herein we report on the potential tumor suppressive properties of Rab7, a GTPase that regulates trafficking of lysosomes.

Kinetics of Interaction of Rab5 and Rab7 with Nucleotides and Magnesium Ions [PDF]
We describe here the kinetics of the interaction of GTP and GDP with the small GTP-binding proteins Rab5 and Rab7. It was possible to make use of the intrinsic fluorescence of these proteins, since Rab5 contains two and Rab7 three tryptophan residues, respectively. With both enzymes, there is a significant decrease in fluorescence on binding GTP and an
