Lamp5 Gene — Lysosomal Associated Membrane Protein 5 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
LAMP5 (Lysosomal Associated Membrane Protein 5) encodes a member of the lysosomal-associated membrane protein (LAMP) family. Formerly known as BAD-LAMP, LAMP5 is expressed in neurons and has been implicated in Alzheimer's disease susceptibility through genome-wide association studies.
LAMP5 is a type I transmembrane protein localized primarily to lysosomes and late endosomes. It is expressed predominantly in the brain, particularly in regions affected in Alzheimer's disease. Genetic variants in LAMP5 have been associated with AD risk.
The LAMP5 gene is located on chromosome 20p13.
