The lysosome-associated membrane protein 2A (LAMP2A) is a critical component of chaperone-mediated autophagy (CMA), a selective degradation pathway that targets cytosolic proteins with a KFERQ-like motif for lysosomal degradation. As one of three splice variants of the LAMP2 gene, LAMP2A is uniquely localized to the lysosomal membrane, where it acts as a receptor for substrate recognition and translocation. Its role in maintaining cellular homeostasis, protein quality control, and stress response has made it a key focus in studies of neurodegenerative diseases, cancer, and metabolic disorders.
Antibodies targeting LAMP2A are essential tools for investigating CMA activity and lysosomal function. They are widely used in Western blotting, immunofluorescence, and immunohistochemistry to assess LAMP2A expression levels, subcellular localization, and dynamics under various physiological or pathological conditions. Specificity is crucial due to structural similarities among LAMP2 isoforms (LAMP2A, LAMP2B, LAMP2C). High-quality anti-LAMP2A antibodies help identify CMA defects in diseases like Alzheimer's, Parkinson's, and Danon disease (caused by LAMP2 mutations). Additionally, these antibodies serve as lysosomal markers in organelle studies. Most commercially available LAMP2A antibodies are raised against unique C-terminal epitopes of the isoform, with validation often performed using knockout controls or isoform-specific overexpression systems.
