Characterising alternate splicing and tissue specific expression in the chicken from ESTs.

ABSTRACT: Alternate splicing is believed to produce the greatest diversity in transcriptional complexity and function in eukaryotic species. In this study, we present an analysis of alternative splicing events that occur in the chicken, using the recently sequenced genomic sequence and over 580,000 EST sequences mapped back to the genome. A carefully controlled EST-to-genome mapping pipeline is presented, based around the EXONERATE program using the est2genome model, which also considers several quality control steps to filter out erroneous matches. The data is then used to estimate the level of alternate splicing events with respect to Ensembl predicted transcripts. The EST-genome mappings are characterised at the exon level, in order to classify individual splicing events and provide estimates of
