Target

  • Function
    Implicated in tumor cell metastasis. May function in protection of the lysosomal membrane from autodigestion, maintenance of the acidic environment of the lysosome, adhesion when expressed on the cell surface (plasma membrane), and inter- and intracellular signal transduction. Protects cells from the toxic effects of methylating mutagens.
  • Tissue specificity
    Isoform LAMP-2A is highly expressed in placenta, lung and liver, less in kidney and pancreas, low in brain and skeletal muscle. Isoform LAMP-2B is highly expressed in skeletal muscle, less in brain, placenta, lung, kidney and pancreas, very low in liver.
  • Involvement in disease
    Danon disease
  • Sequence similarities
    Belongs to the LAMP family.
  • Post-translational
    modifications
    O- and N-glycosylated; some of the 16 N-linked glycans are polylactosaminoglycans.
  • Cellular localization
    Cell membrane. Endosome membrane. Lysosome membrane. This protein shuttles between lysosomes, endosomes, and the plasma membrane.
