  • Function
    Receptor for hyaluronic acid (HA). Mediates cell-cell and cell-matrix interactions through its affinity for HA, and possibly also through its affinity for other ligands such as osteopontin, collagens, and matrix metalloproteinases (MMPs). Adhesion with HA plays an important role in cell migration, tumor growth and progression. Also involved in lymphocyte activation, recirculation and homing, and in hematopoiesis. Altered expression or dysfunction causes numerous pathogenic phenotypes. Great protein heterogeneity due to numerous alternative splicing and post-translational modification events.
  • Tissue specificity
    Isoform 10 (epithelial isoform) is expressed by cells of epithelium and highly expressed by carcinomas. Expression is repressed in neuroblastoma cells.
  • Sequence similarities
    Contains 1 Link domain.
  • Domain
    The lectin-like LINK domain is responsible for hyaluronan binding.
  • Post-translational
    Proteolytically cleaved in the extracellular matrix by specific proteinases (possibly MMPs) in several cell lines and tumors.
    O-glycosylated; contains more-or-less-sulfated chondroitin sulfate glycans, whose number may affect the accessibility of specific proteinases to their cleavage site(s).
    Phosphorylated; activation of PKC results in the dephosphorylation of Ser-706 (constitutive phosphorylation site), and the phosphorylation of Ser-672.

Anti-CD44 antibody [MEM-85] (Phycoerythrin) images

  • Umbilical cord mesenchymal stem cells were treated or not with chondroitinase ABC or Hylase and placed in co-culture with inflammatory cells seeded in a transwell insert with a 0.44-μm pore. Expression and localization of TSG6 and CD44 were evaluated by immunocytochemistry using immunoflurence with ab23777.
