Background: CD44
CD44, also known as ECMR-III, Hermes, Pgp1, Ly-24, GP90, or HUTCH, is a ubiquitously expressed protein that is the major 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. In cancer cells, may play an important role in invadopodia formation. Also involved in lymphocyte activation, recirculation and homing, and in hematopoiesis. Mouse CD44 has a 22 amino acid (aa) signal sequence, an extracellular domain (ECD) with a 100 aa hyaluronan-binding disulfide-stabilized link region and a 48-463 aa stem region, a 21 aa transmembrane domain, and a 72 aa cytoplasmic domain. CD44 exists as a large number of different isoforms due to alternative RNA splicing. Clone IM7.8.1 has been reported to recognize all isoforms of CD44.
