abstract：:Alternative splicing (AS) patterns have diverged rapidly during vertebrate evolution, yet the functions of most species- and lineage-specific splicing events are not known. We observe that mammalian-specific AS events are enriched in transcript sequences encoding intrinsically disordered regions (IDRs) of proteins, in...
