| Specificity | CD44v10 Approximant 116 kDa) Recent studies indicate that the expression of CD44 on the cell surface changes profoundly during tumor metastasis, particularly during the progression of various carcinomas. Sequencing analysis reveals that CD44 exists in different forms (at least 15 isoforms have been identified) that are variants of the common or standard hemopoietic form CD44s. Specifically, the human CD44 gene contains 19 exons, out of which 10 exons can potentially be alternatively spliced. In particular, CD44s contains exons 1-15 and exons 15-19. The other exons (e.g. 6-14) are also spliced in a variety of different cells. For example, epithelial cells contain exons 12-14 inserted into the CD44s transcripts. This isoform has been designated as CD44E. Other CD44 variants CD44v) have the same sequences at the two ends of the molecule, but differ in a middle region (with different numbers of additional exons) located on the external side of the cell membrane. It has been suggested that expression of CD44 variants with the additional exon 14 (SO-called v10) is responsible for tumor progression and metastasis. In fact, CD44v10 expression has been used as an indicator of metastasis. |

| Entrez Gene Number |
|
| Entrez Gene Summary | The protein encoded by this gene is a cell-surface glycoprotein involved in cell-cell interactions, cell adhesion and migration. It is a receptor for hyaluronic acid (HA) and can also interact with other ligands, such as osteopontin, collagens, and matrix metalloproteinases (MMPs). This protein participates in a wide variety of cellular functions including lymphocyte activation, recirculation and homing, hematopoiesis, and tumor metastasis. Transcripts for this gene undergo complex alternative splicing that results in many functionally distinct isoforms, however, the full length nature of some of these variants has not been determined. Alternative splicing is the basis for the structural and functional diversity of this protein, and may be related to tumor metastasis. |

| UniProt Summary | FUNCTION: SwissProt: P16070 # 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. Also involved in lymphocyte activation, recirculation and homing, and in hematopoiesis. Altered expression or dysfunction causes numerous pathogenic phenotypes. Great protein heterogeneity due to numerous alternative splicing and post-translational modification events. SIZE: 742 amino acids; 81554 Da SUBUNIT: Interacts with HA, as well as other glycosaminoglycans, collagen, laminin, and fibronectin via its N-terminal segment. Interacts with ANK, the ERM proteins (VIL2, RDX and MSN), and NF2 via its C-terminal segment. SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein. TISSUE SPECIFICITY: An epithelial isoform (CD44E) is expressed by cells of epithelium and highly expressed by carcinomas. An hematopoietic isoform (CD44H) is expressed by cells of mesodermal origin. Expression is repressed in neuroblastoma cells. PTM: Proteolytically cleaved in the extracellular matrix by specific proteinases (possibly MMPs) in several cell lines and tumors. & N-glycosylated. & O-glycosylated; contains more-or-less-sulfated chondroitin sulfate glycans, whose number may affect the accessibility of specific proteinases to their cleavage site(s). & Phosphorylated; activation of PKC results in the dephosphorylation of Ser-706 (constitutive phosphorylation site), and the phosphorylation of Ser-672. SIMILARITY: SwissProt: P16070 ## Contains 1 Link domain. |
