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.
Isoform 10 (epithelial isoform) is expressed by cells of epithelium and highly expressed by carcinomas. Expression is repressed in neuroblastoma cells.
Contains 1 Link domain.
The lectin-like LINK domain is responsible for hyaluronan binding.
Proteolytically cleaved in the extracellular matrix by specific proteinases (possibly MMPs) in several cell lines and tumors. N-glycosylated. 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.

ab40983 staining CD44 in Human OSCC tongue tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 1% serum + 0.1% BSA for 30 minutes at 21°C. Samples were incubated with primary antibody (1/100 in blocking buffer) for 2 hours at 21°C. An Alexa Fluor®488-conjugated Goat anti-rat IgG monoclonal(1/400) was used as the secondary antibody.

ab40983 staining mouse embryonic stem cells by Flow Cytometery. Cells were fixed in paraformaldehyde and gating was done on live cells. The primary antibody was diluted 1/100 and incubated with sample for 30 minutes at 25°C. A PE conjugated goat polyclonal to rat IgG, diluted 1/100 was used as secondary.
