Systematical identification of splicing regulatory cis-elements and cognate trans-factors

Minigene reporter for identification and analysis of cis elements and trans factors affecting pre-mRNA splicing.

All human genes contain a diverse array of cis-acting elements within introns and exons that are required for correct and efficient precursor messenger RNA (pre-mRNA) splicing. Recent computational analyses predict that most human exons contain elements required for splicing coinciding with an appreciation for the high frequency with which mutations that disruption pre-mRNA splicing cause disea...

Coevolutionary networks of splicing cis-regulatory elements.

Accurate and efficient splicing of eukaryotic pre-mRNAs requires recognition by trans-acting factors of a complex array of cis-acting RNA elements. Here, we developed a generalized Bayesian network to model the coevolution of splicing cis elements in diverse eukaryotic taxa. Cross-exon but not cross-intron compensatory interactions between the 5' splice site (5'ss) and 3' splice site (3'ss) wer...

Identification of cis-Acting Elements and Splicing Factors Involved in the Regulation of BIM Pre-mRNA Splicing

Aberrant changes in the expression of the pro-apoptotic protein, BCL-2-like 11 (BIM), can result in either impaired or excessive apoptosis, which can contribute to tumorigenesis and degenerative disorders, respectively. Altering BIM pre-mRNA splicing is an attractive approach to modulate apoptosis because BIM activity is partly determined by the alternative splicing of exons 3 or 4, whereby exo...

Identification of cis-regulatory elements for MECP2 expression.

Rett syndrome (RTT) is an X-linked dominant disabling neurodevelopmental disorder caused by loss of function mutations in the MECP2 gene, located at Xq28, which encodes a multifunctional protein. MECP2 expression is regulated in a developmental stage and cell-type-specific manner. The need for tightly controlled MeCP2 levels in brain is strongly suggested by neurologically abnormal phenotypes o...
