About CD44
This gene has 38 transcripts (splice variants), 133 orthologues, 1 paralogue and is associated with 1 phenotype. Broad expression in skin (RPKM 96.7), appendix (RPKM 60.6) and 19 other tissues.
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. [provided by RefSeq, Jul 2008]
