Background: LAMP-1/CD107a
LAMP-1 plays an important role in autophagy-mediated ATP-release during apoptosis where lysosomes containing intracellular ATP migrate to the plasma membrane and, during exocytosis, LAMP-1 is exposed to the cell surface (5). Studies have found that knockdown of LAMP-1 blocks the ATP release from the cell (5). Furthermore, an absence of LAMP-1 and LAMP-2 leads to an accumulation of lysosomal cholesterol (6). Lysosomal membrane dysfunction or defects has also been associated with disease development (6,7). For example, one feature of pancreatitis is autophagy impairment which is caused by lysosomal dysfunction and a corresponding decrease in lysosomal-membrane associated proteins LAMP-1 and LAMP-2 (7).
