| Description | Mouse monoclonal antibody to human CD44 Affinity purified clone BRIC 235. CD44 (also known as Pgp-1, ECMR III, Hermes antigen, p801, H- CAM) is a cell membrane glycoprotein of apparent molecular weight 80 kDa. The full amino acid sequence has been deduced from cDNA. It is heavily glycosylated with both N- and O- glycans. The extracellular part of CD44 comprises an N- terminal disulphide bonded domain and an O- glycosylated domain. CD44 carries the Ina and Inb blood group antigens. There is a strong association between CD44 and the cytoskeleton. CD44 is thought to be involved in mediating cell:cell adhesion particularly lymphocyte- endothelial cell interactions important for lymphocyte migration from blood to lymph nodes and mucosal associated lymph organs. CD44 is a member of the hyaladherin family of hyaluronan-binding proteins, with a structure similar to selectins, and is the principal cell surface receptor for Hyaluronate. Antibodies in CD44 may facilitate haemopoietic engraftment4. CD44 also functions as an adhesion, hyaluronan, fibronectin, osteopontin and MIP-1b receptor and as a co-stimulatory molecule. CD44 is found on a broad range of haemopoietic cells such as lymphoid cells, myeloid cells, fibroblasts, endothelial cells, epithelial cells, erythroid cells and the nervous system, but not platelets5. It is found on brain, heart, liver, thymus, kidney and colon epithelium. CD44 has been mapped to chromosome 11p. There are approximately 10,000 CD44 molecules per erythrocyte. |
