I have been using MISO to identify mis-spliced exons in a human dataset and now I am trying to compare these mis-spliced human exons to another dataset from a mouse model with similar splicing events. Does anyone know of a resource to identify orthologous exons between human and mouse? I've searched through Biomart many times and can't seem to find this. I have also been "blat-ing" the human sequence against a query of mouse exon sequences but this seems to be giving many false negatives.
Thanks a lot!
