A comparison of alternative splicing within the human and mouse basigin locus. In total the human BSG protein-coding locus contains 13 transcript models in GENCODE v16, four of which are shown here for clarity (A–D). Similarly, three CDSs from the orthologous mouse Bsg locus are shown (a–c), taken from the manual annotation resources of the Vega project (Wilming et al. 2008). Annotated CDSs are highlighted in green, UTRs in red. The human locus contains an intron 5 bp downstream from the termination codon that has no counterpart in the mouse locus; other minor UTR variations have been omitted. Dashed lines indicate exon level orthology; intron sizes are to approximate scale only. Transcript models A and a, and B and b, are thus equivalent between human and mouse, and each is supported by transcriptional evidence in both species.
