Target Information

CD44 cell surface antigen is a 100 kDa type I transmembrane glycoprotein widely expressed on human leukocytes, white matter of the brain, and epithelial cells of the intestine and breast. Several isoforms of CD44 exist, including the predominant CD44H isoform detected in many normal tissues. CD44 serves as a receptor for hyaluronic acid (HA) and plays roles in cell-cell interactions, adhesion, and migration. It participates in lymphocyte activation, recirculation, and homing, and may be upregulated in certain carcinomas associated with metastatic potential.

CD44 is expressed by hematopoietic and non-hematopoietic cells, epithelial tissues, and filopodia in cultured keratinocytes. Bone marrow myeloid cells and memory T cells express CD44 at high levels, and peripheral B and T cells can upregulate its expression upon stimulation. The CD44 gene undergoes complex alternative splicing, producing many distinct isoforms that contribute to structural and functional diversity. Diseases associated with CD44 dysfunction include superficial keratitis and lichen sclerosus, and CD44 may be related to tumor metastasis formation.
