Abstract:
VPS10P (vacuolar protein sorting 10 protein) domain receptors consitute a family of sorting receptors which are responsible for directing their protein cargo into destined subcellular localization. Functions of VPS10P domain receptors have been well-described in neurons, where efficient sorting of proteins is crucial for cell viability. Dysfunctions in neuronal actions of VPS10P domain receptors are linked to disturbances in neuronal plasticity and development of neurodegenerative disorders. VPS10P domain receptors are also crucial for lipid metabolism, mainly through transport of lipolytic enzymes or influencing the uptake of lipoproteins by the cells. Emerging evidence suggests that VPS10P domain receptors can play important roles in immune response evoked by immune or glial cells. They are also key players in pathogenesis of cancers.

Overview of Protein Sorting and Transport
Protein sorting can be of two types: signal-based sorting and vesicle-based trafficking. In signal-based sorting, specific amino acid sequences called sorting signals target proteins to the proper location inside the cell either via gated transport or by protein translocation. In gated transport, folded...
ER Retrieval Pathway
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...
Nuclear Protein Sorting
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...
