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 some epithelial cells of the intestine and breast.
Several isoforms of CD44 exist, including the predominant CD44H isoform detected in many normal tissues.
CD44 acts as a receptor for hyaluronic acid (HA) and plays roles in cell-cell interactions, adhesion, and migration. It is involved in lymphocyte activation, recirculation, and homing.
Expression of CD44 may be upregulated in certain carcinomas, potentially related to metastatic potential. It is expressed by hematopoietic and non-hematopoietic cells, epithelial tissues, and filopodia in cultured keratinocytes.
Bone marrow myeloid cells and memory T cells show high CD44 expression, while peripheral B and T cells can upregulate CD44 in response to stimulation.
CD44 transcripts undergo complex alternative splicing, resulting in diverse isoforms with distinct functions. Diseases associated with CD44 dysfunction include superficial keratitis and lichen sclerosus, and CD44 may be implicated in tumor metastasis formation.
