CD44 antigen is a cell-surface glycoprotein involved in cell–cell interactions, cell adhesion and migration.
CD44 is expressed in a large number of mammalian cell types.
CD44 is a receptor for hyaluronic acid and can also interact with other ligands, such as osteopontin, collagens, and matrix metalloproteinases (MMPs).
CD44 function is controlled by its posttranslational modifications.
One critical modification involves discrete sialofucosylations rendering the selectin-binding glycoform of CD44 called HCELL (for Hematopoietic Cell E-selectin/L-selectin Ligand).
CD44 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.
特徴
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 48.7 kDa.
The protein migrates as 55-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
