Sortilin 1 (SORT1) is a member of the VPS10P family of sorting receptors that plays critical roles in intracellular protein trafficking, lipoprotein metabolism, and neuronal signaling. It functions as a sorting receptor that directs proteins to various cellular compartments including lysosomes, the cell surface, and the Golgi apparatus.
SORT1 encodes a type I transmembrane protein that functions as a sorting receptor:
SORT1 is highly expressed in the central nervous system:
SORT1 has been implicated in Alzheimer's disease pathogenesis through multiple mechanisms:
Genetic Evidence:
Molecular Mechanisms:
SORT1 interacts with several proteins relevant to neurodegeneration:
| Protein | Interaction | Relevance to Disease |
|---|---|---|
| APP | Direct binding | APP processing, Aβ generation |
| ApoE | Receptor-ligand | Lipid metabolism, AD risk |
| BDNF | Receptor binding | Neurotrophin signaling |
| Progranulin | Binding | FTD pathogenesis |
| Neurotensin | Ligand | Signal transduction |
