• Lysosomes are cell organelles found in most animal cells. (wikipedia.org)
  • Both LAMP1 and LAMP2 have been found expressed on the surface of cancerous tumors, specifically in cells of highly metastatic cancer such as colon cancer and melanoma. (wikipedia.org)
  • They are rarely found on the plasma membranes of normal cells, and are found more on highly metastatic tumors than on poorly metastatic ones. (wikipedia.org)
  • LAMP2, along with LAMP1, interact with E-selectin and galectins to mediate the adhesion of some cancer cells to the ECM. (wikipedia.org)
  • It has also been shown that the down-regulation of LAMP2 could both reduce the resistance of breast cancer cells to the paclitaxel and could inhibit cell proliferation in multiple myeloma cells. (wikipedia.org)
  • In a study of glial tumors, the cell membranes of glial and endothelial cells were found to contain LAMP1 and LAMP2, while YKL-40 (a different glycoprotein) was found in the cytoplasm. (wikipedia.org)
  • Cells that lack LAMP2 express normal levels of VAMP8, but fail to accumulate STX17 on autophagosomes, which is the most likely explanation for the lack of fusion between autophagosomes and lysosomes (PubMed:27628032). (nih.gov)
  • It may also function in the protection, maintenance, and adhesion of the lysosome. (wikipedia.org)
