Background: LAMP-2/CD107b

LAMP-2 (Lysosome-associated membrane protein 2) is a single-pass type I membrane protein that belongs to a family of membrane glycoproteins (~40 KDa). LAMP-2 protein is encoded by nine exons, with the first 8 exons and a portion of exon 9 encoding the highly glycosylated protein domains within the lysosomal lumen. The transmembrane and cytosolic carboxy-terminal domains of LAMP-2 are encoded by the remaining sequence of exon 9 and conform the receptor for targeting proteins to the lysosome. Splicing of exon 9 in the LAMP-2 pre mRNA leads to various splice forms with distinct cytosolic domains. Three splice variants, LAMP-2A, -2B and -2C, have been identified which shuttle between the plasma membrane, endosomal compartment and lysosomes (1). Tissue specific expression has been described for each LAMP-2 splice variant, with LAMP-2A being more ubiquitously expressed (e.g., placenta, lung, liver, pancreas and prostate), LAMP-2B predominantly expressed in skeletal muscle and LAMP-2C in brain tissue (1). All LAMP-2 splice variants participate in lysosomal degradation processes. LAMP-2A is the only variant that serves as a receptor targeting proteins for lysosomal degradation in chaperone-mediated autophagy (2,3). LAMP-2B is essential for macroautophagy in cardiomyocytes, where it facilitates autophagosome-lysosome fusion. LAMP-2B mutations underscore the myopathy and severe hypertrophic cardiomyopathy in Danon disease which results from deficits in autophagy (1, 4). Vasculopathy of coronary and cerebral arteries is a rare phenotype in Danon patients that is also associated with deficient autophagy processing of proteins and cellular organelles (5). LAMP2C serves as a receptor for DNA and RNA, facilitating their lysosomal degradation through DNA-autophagy and RNA-autophagy, respectively (1).
