Target Information

CD44 cell surface antigen is a 100 kDa type 1 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 is involved in cell-cell interactions, adhesion, and migration. It plays roles in lymphocyte activation, recirculation, and homing. CD44 expression may be upregulated in certain carcinomas and is associated with 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 express CD44 at high levels, and peripheral B and T cells can upregulate CD44 expression upon stimulation.

Transcripts for the CD44 gene undergo complex alternative splicing resulting in many functionally distinct isoforms. Alternative splicing contributes to the structural and functional diversity of the CD44 protein. Diseases associated with CD44 dysfunction include superficial keratitis and lichen sclerosus. CD44 is also implicated in tumor metastasis formation.
