Vps16 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.
VPS16 (Vacuolar Protein Sorting 16 Homolog) is a gene located on chromosome 13q14.2 that encodes a component of the HOPS (Homotypic fusion and Vacuole Protein Sorting) complex. It plays essential roles in late endosomal and lysosomal trafficking.

VPS16 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
VPS16 dysfunction contributes to neurodegenerative processes:
- Mechanism: Impaired autophagic-lysosomal pathway
VPS16 is implicated in PD:
VPS16 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 VPS16
