CD44 is a ubiquitously expressed type 1 transmembrane glycoprotein and proteoglycan, otherwise known as phagocytic glycoprotein 1 (pgp 1), which acts as a receptor for the major extracellular matrix component hyaluronate, and also binds other ligands including collagen and matrix metalloproteinases (MMPs).
CD44 is known to play a role in cell-cell interactions, cell adhesion, the activation and homing of lymphocytes, cell migration, hematopoiesis and metastasis, and exists as a number of isoforms generated by the alternative RNA splicing of at least 10 variant exons (CD44v).
Applications:Suitable for use in Immunohistochemistry.
