The Pax-5 Gene Is Alternatively Spliced during B-cell Development

Alternatively Spliced Tissue Factor Is Not Sufficient for Embryonic Development

Tissue factor (TF) triggers blood coagulation and is translated from two mRNA splice isoforms, encoding membrane-anchored full-length TF (flTF) and soluble alternatively-spliced TF (asTF). The complete knockout of TF in mice causes embryonic lethality associated with failure of the yolk sac vasculature. Although asTF plays roles in postnatal angiogenesis, it is unknown whether it activates coag...

Exon 2 of the gene for neural cell adhesion molecule L1 is alternatively spliced in B cells.

L1CAM is a neural cell adhesion molecule expressed mainly on neurones' cell surface and plays an important role in the developing fetal brain. Recently, we have shown that mutations in the gene encoding L1CAM are responsible for three related neurological disorders including the most common form of inherited hydrocephalus. During our genetic analysis, we have discovered that L1CAM is also expre...

A sugarcane R2R3-MYB transcription factor gene is alternatively spliced during drought stress

MYB transcription factors of the R2R3-MYB family have been shown to play important roles in many plant processes. A sugarcane R2R3-MYB gene (ScMYB2) and its two alternative forms of transcript (ScMYB2S1 and ScMYB2S2) were identified in this study. The deduced protein of ScMYB2S1 is a typical plant R2R3-MYB protein, while ScMYB2S2 encodes a truncated protein. Real-time qPCR analysis revealed tha...

Tropoelastin pre-mRNA is alternatively spliced at different frequencies during rat lung development.

An alternatively spliced form of CD79b gene may account for altered B-cell receptor expression in B-chronic lymphocytic leukemia.

Several functional anomalies of B-chronic lymphocytic leukemia (B-CLL) cells may be explained by abnormalities of the B-cell receptor (BCR), a multimeric complex formed by the sIg homodimer and the noncovalently bound heterodimer Igalpha/Igbeta (CD79a/CD79b). Because the expression of the extracellular Ig-like domain of CD79b has been reported to be absent in the cells of most CLL cases, we hav...
