| Background Information | Lysosyme-associated membrane proteins (LAMP) are transmembrane lysosomal glycoproteins, which share a common Gly-Tyr motif as a lysosomal targeting signal. While LAMP-1 and LAMP-2 contain type 1 transmembrane domains, LAMP-3 contains a transmembrane 4 superfamily domain, tetraspanin. FceRI-mediated stimulation of basophils causes LAMP-3 to be translocated from its intracellular localization to the plasma membrane. LAMP-3 thereby serves as a reliable marker for basophil activation. LAMP-3 expression is known to be reported in human bone marrow mast cells and in leukemic human mast cell line (HMC-1), among other cell lines. LAMP3 is shown to be regulated by hypoxia in a panel of tumor cells, via the unfolded protein response (UPR). UPR is a mechanism of adaptation to endoplasmic reticulum stress and is demonstrated to contribute to hypoxic adaptation in tumors through multiple mechanisms. |

| Entrez Gene Number |
|
| Entrez Gene Summary | Dendritic cells (DCs) are the most potent antigen-presenting cells. Immature DCs efficiently capture antigens and differentiate into interdigitating dendritic cells (IDCs) in lymphoid tissues that induce primary T-cell responses (summary by de Saint-Vis et al., 1998). |

| UniProt Number |
|
| UniProt Summary | FUNCTION: Might change the lysosome function after the transfer of peptide-MHC class II molecules to the surface of dendritic cells. SUBCELLULAR LOCALIZATION: Lysosome membrane; Single-pass type I membrane protein. TISSUE SPECIFICITY: Expressed in lymphoid organs and dendritic cells. Expressed in lung. Up-regulated in carcinomas of the esophagus, colon, rectum, ureter, stomach, breast, fallopian tube, thyroid and parotid tissues. |
| Molecular Weight | ~65 kDa observed. The calculated molecular weight of this protein is 41 kDa, but has been observed at ~65-90 kDa due to glycosolation (de Saint-Vis, B., et al. (1998). Immunity. 9(3):325-336). |
