The VPS35 D620N mutation impairs retromer complex assembly at endosomal membranes, disrupting the retrieval of GCase-containing vesicles from endosomes back to the lysosome. Under physiological conditions, the retromer recognizes a specific sorting motif on GCase (possibly within its cytosolic tail) and directs it toward the lysosome via the CLIP1-positive tubular network. The VPS35 D620N mutation specifically destabilizes the retromer-cargo interaction without affecting overall complex integrit
## Mechanistic Overview
VPS35 retromer activation prevents endosomal tau templating across all brain regions and disease stages starts from the claim that modulating VPS35 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview VPS35 retromer activation prevents endosomal tau templating across all brain regions and disease stages starts from the claim that modulating VPS35 within the disease context of neur
