Lysosomes are membrane-bound organelles found within the cytoplasm of most cells, which contain hydrolytic enzymes and act as the major compartment for heterophagic and autophagic digestion. Members of the lysosomal-associated membrane protein family (LAMPS) are believed to play an important role in protecting the lysosomal membrane from protease degradation and are involved in lectin-mediated cell adhesion. Evidence shows that CD107b is involved in the lysosomal uptake of cytosolic proteins and the endocytic pathway and human studies have revealed a correlation between the level of surface expression of CD107b on tumor cells and their metastatic potential.
