Lysosomal Associated Membrane Protein 3 (Lamp3) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Lysosomal Associated Membrane Protein 3 (LAMP3), also known as DC-LAMP or CD208, is a lysosomal membrane protein primarily expressed in dendritic cells and certain epithelial cells. It is encoded by the LAMP3 gene located on chromosome 3q27.2.

LAMP3 shares structural features with LAMP1 and LAMP2:
Unlike LAMP1/2, LAMP3 has a restricted tissue distribution.
LAMP3 is primarily known for its role in immune cells:
In AD, LAMP3 may play a role in:
LAMP3 involvement in PD includes:
LAMP3 is overexpressed in several cancers:
| Approach | Mechanism | Status |
|---|---|---|
| LAMP3-targeting | Cancer immunotherapy | Research |
| Immune modulation | Neuroinflammation | Research |
| Disease | Role | Evidence |
|---|---|---|
| Alzheimer's Disease | Microglial involvement | LAMP3+ cells in AD brain[1] |
| Parkinson's Disease | Neuroinflammation | Altered expression in PD[2] |
| Cancer | Metastasis | Overexpressed in multiple cancers |
