Lysosomal-associated membrane protein 1 (LAMP-1) also known as lysosome-associated membrane glycoprotein 1 and CD107a (Cluster of Differentiation 107a), is a protein that in humans is encoded by the LAMP1 gene. The human LAMP1 gene is located on the long arm (q) of chromosome 13 at region 3, band 4 (13q34).

Lysosomal-associated membrane protein 1 is a glycoprotein from a family of Lysosome-associated membrane glycoproteins.^[1] The LAMP-1 glycoprotein is a type I transmembrane protein^[2] which is expressed at high or medium levels in at least 76 different normal tissue cell types.^[3] It resides primarily across lysosomal membranes,^[4] and functions to provide selectins with carbohydrate ligands.^[1] CD107a has also been shown to be a marker of degranulation on lymphocytes such as CD8+ and NK cells.^[5] and may also play a role in tumor cell differentiation and metastasis.

Structure

Residing primarily across lysosomal membranes, these glycoproteins consist of a large, highly glycosylated end with N-linked carbon chains on the luminal side of the membrane, and a short C-terminal tail^[2] exposed to the cytoplasm.^[4] The extracytoplasmic region contains a hinge-like structure which can form disulphide bridges homologous to those observed in human immunoglobulin A.^[4] Other characteristics of the structure of the LAMP-1 glycoproteins include:

A polypeptide core of ~40kDa^[4]
18 {N-glycosylation} sites to help with the addition of sugar chains^[6]
Polylactosamine attachments which protect the glyocoprotein from degradation by lysosomal proteases^[6]
Significant quantities of polylactosaminoglycan and sialic acid to traverse the trans-Golgi cisternae.^[6]
poly-N-acetyllactosamine groups which are involved in interactions with selectin and other glycan-binding proteins^[7]

Function

LAMP1 and LAMP2 glycoproteins comprise 50% of all lysosomal membrane proteins,^[2] and are thought to be responsible in part for maintaining lysosomal integrity, pH and catabolism.^[2]^[7] The expression of LAMP1 and LAMP2 glycoproteins are linked, as deficiencies in LAMP1 gene will lead to increased expression of LAMP2 glycoproteins.^[7] The two are therefore thought to share similar functions in vivo.^[2] However, this makes the determining the precise function of LAMP1 difficult, because while the LAMP1 deficient phenotype is little different than the wild type due to LAMP2 up regulation,^[2]^[7] the LAMP1/LAMP2 double deficient phenotype leads to embryonic lethality.^[7]

Although the LAMP1 glycoproteins primarily reside across lysosomal membranes, in certain cases they can be expressed across the plasma membrane of the cell.^[7] Expression of LAMP1 at the cell surface can occur due to lysosomal fusion with the cell membrane.^[8] Cell surface expression of LAMP1 can serve as a ligand for selectins^[9]^[10] and help mediate cell-cell adhesion.^[11] Accordingly, cell surface expression of LAMP1 is seen in cells with migratory or invasive functions, such as cytotoxic T cells, platelets and macrophages.^[12] Cell surface expression of LAMP1 and LAMP2 is also often seen in cancer cells,^[12]^[13] particularly cancers with high metastatic potential, such as colon carcinoma and melanoma,^[12] and has been shown to correlate with their metastatic potential.^[7]

Role in cancer

LAMP1 expression on the surface of tumor cells has been observed for a number of different cancer types, particularly in highly metastatic cancers such as pancreatic cancer,^[14]^[15] colon cancer^[12]^[13] and melanoma.^[12]^[13] The structure of LAMP1 correlates with differentiation^[4]^[16] and metastatic potential^[7] of tumor cells as it is thought to help mediate cell-cell adhesion ^[13] and migration.^[11]^[14] Indeed, the adhesion of some cancer cells to the extracellular matrix is mediated by interactions between LAMP1 and LAMP2 and E-selectin and galectins, with the LAMPs serving as ligands for the cell-adhesion molecules.^[13]

Cell membrane expression of LAMP-1 observed in the following cancer types:
