VPS13C (Vacuolar Protein Sorting 13 Homolog C) is a large lipid transfer protein involved in endosomal and lysosomal trafficking. It plays a role in mitochondrial quality control and has been implicated in early-onset Parkinson's disease. VPS13C localizes to the outer mitochondrial membrane and is involved in tethering mitochondria to endolysosomal compartments, facilitating the removal of damaged mitochondria through mitophagy. Mutations cause autosomal recessive PD with rapid progression and cognitive decline.
VPS13C is a member of the VPS13 family of lipid-transfer proteins. These proteins are characterized by their ability to transport lipids between membranes via arod-like bridging.
- Large protein (~3,100 amino acids)
- Contains multiple protein-binding domains
- Has a lipid-binding cavity
- Associates with various cellular membranes
- Lipid transfer: Moves lipids between organelles
- Mitochondrial quality control: Involved in mitophagy
- Endolysosomal trafficking: Regulates lysosomal function
- Cellular stress response: Activated by mitochondrial damage
VPS13C mutations cause autosomal recessive early-onset PD:
- Biallelic loss-of-function mutations identified in PD patients
- Associated with early onset (<40 years) and rapid progression
- Patients show typical PD phenotype with levodopa response
- Often presents with cognitive decline
- Impaired mitophagy leads to accumulation of damaged mitochondria
- Increased oxidative stress from dysfunctional mitochondria
- Reduced cellular viability under metabolic stress
- Interaction with PINK1/Parkin pathway
