Vps35 Mutant Neurons is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
VPS35 (Vacuolar protein sorting 35) is a component of the retromer complex, essential for endosomal trafficking and protein recycling. The D620N mutation causes autosomal dominant Parkinson's disease, disrupting retromer function and leading to impaired protein sorting and neurodegeneration.
This page provides comprehensive information about the subject's role in neurodegenerative diseases. The subject participates in various molecular pathways and cellular processes relevant to Alzheimer's disease, Parkinson's disease, and related conditions.
