Gene Information

human ... LAMP1(3916)

General description

Lysosome-associated membrane glycoprotein 1 (UniProt: P11279; also known as LAMP-1, Lysosome-associated membrane protein 1, CD107 antigen-like family member A, CD107a) is encoded by the LAMP1 gene (Gene ID: 3916) in human. LAMP-1 and LAMP-2 are two highly glycosylated proteins found in the lysosomal membrane. They may contribute up to 50% of all proteins present in the lysosomal membranes. They are known to maintain the lysosomal acidification and lysosomal membrane integrity. Extensive N-glycosylation on LAMP-1 and 2 to protects them from the lysosomal proteolysis. However, higher levels of poly-N-acetyllactosamines on LAMP-1 and 2 have been correlated with decreased cellular differentiation and enhanced metastatic potential. LAMP-1 is a single-pass type I transmembrane protein that contains a large lumenal domain (aa 29-382), a transmembrane domain (aa 383-405), and a short C-terminal cytoplasmic tail (aa 406-417). LAMP-1 is synthesized with a signal peptide (aa 1-28) that is subsequently cleaved in the mature form. LAMP-1 presents carbohydrate ligands to selectins and is also reported to act as a receptor for Lassa virus protein. Two isoforms of LAMP-1 have been described that are produced by alternative splicing. (Ref.: Tan, K-P., et al. (2016). Cell Death Dis. 7, e2347).
