Proteoglycan forms of the lymphocyte homing receptor CD44 are alternatively spliced variants containing the v3 exon
The CD44 cell surface glycoprotein is expressed on a broad range of different tissues as multiple isoforms containing from one to ten alternatively spliced exons v1-v10 inserted within the extracellular domain. Differential glycosylation generates still further variability, yielding both N- and O-glycan-modified forms of CD44 in addition to proteoglycan-like variants containing chondroitin sulp...
متن کاملGenomic structure of DNA encoding the lymphocyte homing receptor CD44 reveals at least 12 alternatively spliced exons.
The CD44 molecule is known to display extensive size heterogeneity, which has been attributed both to alternative splicing and to differential glycosylation within the extracellular domain. Although the presence of several alternative exons has been partly inferred from cDNA sequencing, the precise intron-exon organization of the CD44 gene has not been described to date to our knowledge. In the...
متن کاملAlternatively spliced androgen receptor variants.
Alternative splicing is an important mechanism for increasing functional diversity from a limited set of genes. Deregulation of this process is common in diverse pathologic conditions. The androgen receptor (AR) is a steroid receptor transcription factor with functions critical for normal male development as well as the growth and survival of normal and cancerous prostate tissue. Studies of AR ...
متن کاملCD44 isoforms containing exon V3 are responsible for the presentation of heparin-binding growth factor
Glycosaminoglycan-modified isoforms of CD44 have been implicated in growth factor presentation at sites of inflammation. In the present study we show that COS cell transfectants expressing CD44 isoforms containing the alternatively spliced exon V3 are modified with heparan sulfate (HS). Binding studies with three HS-binding growth factors, basic-fibroblast growth factor (b-FGF), heparin binding...
متن کاملAlu-containing exons are alternatively spliced.
Alu repetitive elements are found in approximately 1.4 million copies in the human genome, comprising more than one-tenth of it. Numerous studies describe exonizations of Alu elements, that is, splicing-mediated insertions of parts of Alu sequences into mature mRNAs. To study the connection between the exonization of Alu elements and alternative splicing, we used a database of ESTs and cDNAs al...
