Background: LAMP-2/CD107b

Lysosomal associated membrane protein 2 (LAMP-2), also known as CD107b and LGP110, is an approximately 110 kDa transmembrane glycoprotein that is a major component of lysosomal membranes (1). Mature mouse LAMP-2 consists of a 354 amino acid (aa) intralumenal domain, a 25 aa transmembrane segment, and a 11 aa cytoplasmic tail (2). Its lumenal domain is organized into two heavily N-glycosylated regions separated by a Ser/Pro-rich linker that carries a minor amount of O‑linked glycosylation (2, 3). Alternate splicing generates two additional mouse LAMP-2 isoforms (LAMP-2B and LAMP-2C) with a substituted juxtamembrane lumenal region, transmembrane segment, and cytoplasmic tail (4). Within the lumenal domain, mouse LAMP-2 shares approximately 64% and 81% aa sequence identity with human and rat LAMP-2, repectively. LAMP-2 itself is subject to lysosomal degradation following cleavage of its lumenal domain (5). It mediates the lysosomal uptake of the chaperone HSC73 in complex with cargo proteins and is required for the lysosomal destruction of autophagic vacuoles (6, 7). In cytotoxic T cells and mast cells, LAMP-2 is expressed in the membranes of intracellular granules that contain effector molecules such as perforin, granzymes, eicosanoids, and histamine (8-10). Up‑regulated LAMP-2 at the plasma membrane serves as an indicator of cell activation of CD8+ T cells, mast cells, monocytes, and platelets (9-12). LAMP-2 is a native ligand for lectins Galectin-1 and Galectin-3 (13‑15).
