Splicing and mouse-human conservation patterns for sense and antisense ESTs from UniGene cluster Mm.148209. The graph depicts the exon-intron splicing structures of transcript sequences belonging to UniGene cluster Mm.148209. Organization of the figure as for Figure 2. The BOU mRNA (GenBank accession NM_011557) is oriented from left to right with respect to genomic contig GA_x5J8B7W5VG6 of the Celera mouse genome assembly. The mRNA encodes synaptonemal complex protein 3. The observed portion of the antisense species does not have protein-level homologies, and consistently overlaps a single internal coding exon of the sense transcript. Many of the antisense species are 3' reads containing an appropriately located poly(A) signal, suggesting that we are observing the 3' end of a larger transcript.
