Lysosomal Associated Membrane Protein 1 (Lamp1) 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 1 (LAMP1) is a major glycoprotein component of the lysosomal membrane. It is encoded by the LAMP1 gene located on chromosome 13q34 and plays critical roles in lysosomal function, autophagy, and cellular homeostasis. [@xilouri2016]
