Human Lysosome-associated membrane glycoprotein 1(LAMP1) ELISA kit

Lysosomal membrane glycoprotein which plays an important role in lysosome biogenesis, autophagy, and cholesterol homeostasis. Plays also an important role in NK-cells cytotoxicity. Mechanistically, participates in cytotoxic granule movement to the cell surface and perforin trafficking to the lytic granule. In addition, protects NK-cells from degranulation-associated damage induced by their own cytotoxic granule content. Presents carbohydrate ligands to selectins. Also implicated in tumor cell metastasis.; (Microbial infection) Acts as a receptor for Lassa virus glycoprotein. Promotes also fusion of the virus with host membrane in less acidic endosomes.; (Microbial infection) Supports the FURIN-mediated cleavage of mumps virus fusion protein F by interacting with both FURIN and the unprocessed form but not the processed form of the viral protein F.
