Experimentally determined ESE data

This site is devoted to exonic splicing enhancers. If you are looking for general information about the alternative splicing of plant genes, we recommend the ASIP (Alternative Splicing in Plants) database at Iowa State or the specialized Genome Annotation Database at TIGR, including Splicing Variations and Non-consensus Splice Sites.


Existing genefinders use information about splice sites and differences between exons and introns, but do not explicitly incorporate information about sequences known as splicing enhancers, which promote incorporation of exons into mRNA (an exception is ExonScan). This is a project to characterize exonic splicing enhancers in Arabidopsis. Although splicing enhancers likely function in splice site selection in many plant genes, and contribute to the regulation of alternative splicing, plant splicing enhancers have not yet been described in detail. Computational analysis of a database of Arabidopsis exons and introns has been used to identify candidate splicing enhancer sequences. The role of these sequences, and sequences from genes that are known to be alternatively spliced, are being tested in transgenic Arabidopsis using a splicing reporter construct. The activity of these enhancers has been examined in transgenes that depend on exon inclusion for expression.
