Background: LAMP-1/CD107a

LAMP-1 (lysosome-associated membrane protein 1), also known as CD107a (cluster of differentiation 107a), is a major component of lysosomal membranes that plays an important role in lysosomal biogenesis, autophagy, and cholesterol metabolism (1). LAMP-1 is a type I transmembrane glycoprotein that is expressed on plasma membranes and the membranes of endosomes, autolysosomes, and lysosomes (1,2). Additionally, LAMP-1/CD107a is a commonly used marker for natural killer (NK) cell degranulation (3). LAMP-1 and another lysosomal-associated membrane protein, LAMP-2, together make up about half of all lysosome membrane proteins (1). Additionally, LAMP-1 has a role in presenting carbohydrate ligands to selectins (2). Human LAMP-1 protein is comprised of 417 amino acids (aa) with a theoretical molecular weight of 44.8 kDa; however, glycosylation can increase the molecular weight upwards of 120 kDa (1, 4). Structurally, LAMP-1 protein contains a large luminal/extracellular domain (29-382 aa), a helical transmembrane domain (383-405 aa), and a short cytoplasmic tail (406-417 aa) (1,2). Additionally, the protein has many N- and O-linked glycosylation sites which helps with stability in the membrane (1,2).

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).
