Definition : Lysosome-associated membrane protein 2 (LAMP2) also known as CD107b (Cluster of Differentiation 107b), is a human gene. Its protein, LAMP2, is one of the lysosome-associated membrane glycoproteins ( LAMPS ).

The protein encoded by this gene is a member of a family of membrane glycoproteins. This glycoprotein provides selectins with carbohydrate ligands. It may play a role in tumor cell metastasis. It may also function in the protection, maintenance, and adhesion of the lysosome.

Alternative splicing of the gene produces three variants - LAMP-2A, LAMP-2B and LAMP-2C.

LAMP-2A is the receptor for chaperone-mediated autophagy. Recently it has been determined that antibodies against LAMP-2 account for a fraction of patients who get a serious kidney disease termed focal necrotizing glomerulonephritis.

LAMP-2B is associated with Danon disease.
