Alternative splicing events are classified into four main subgroups: (i) exon skipping (cassette exons), where the exon can be spliced out of the transcript together with its flanking introns; (ii) alternative 5�ss and (iii) 3�ss selection, which are the results of the recognition of two or more splice sites at one end of an exon; and (iv) intron retention, in wh...

In order to comprehend the influence of evolutionary changes in gene structure on the alternative splicing mechanism, we work on three related subjects: (i) conservation of exonintron sequences, (ii) splice site score changes and (iii) length data changes, across the vertebrate tree. We have analyzed conservation levels of human Alternative cassette exons (ACEs) ...
