Vps8 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
VPS8 (Vacuolar Protein Sorting 8 Homolog) is a gene located on chromosome 6p12.3 that encodes a component of the HOPS (Homotypic fusion and Vacuole Protein Sorting) complex. It plays essential roles in late endosomal and lysosomal trafficking.

VPS8 is a core component of the HOPS complex:
- Late Endosomal Trafficking: Mediates transport to lysosomes
- Autophagosome-Lysosome Fusion: Essential for autophagy completion
- Lysosomal Function: Maintains lysosomal degradation capacity
VPS8 dysfunction contributes to neurodegenerative processes:
- Mechanism: Impaired autophagic-lysosomal pathway
VPS8 is implicated in PD:
VPS8 is expressed ubiquitously with high expression in:
- Brain (cortex, basal ganglia)
- Liver, kidney
- HOPS Complex Modulation: Enhance lysosomal fusion
- Gene Therapy: Viral delivery of wild-type VPS8
