Is there any intron sliding in mammals?

ABSTRACT:

Background

Eukaryotic protein-coding genes consist of exons and introns. Exon-intron borders are conserved between species and thus their changes might be observed only on quite long evolutionary distances. One of the rarest types of change, in which intron relocates over a short distance, is called "intron sliding", but the reality of this event has been debated for a long time. The main idea of a search for intron sliding is to use the most accurate genome annotation and genome sequence, as well as high-quality transcriptome data. We applied them in a search for sliding introns in mammals in order to widen knowledge about the presence or absence of such phenomena in this group.

Results

We didn't find any significant evidence of intron sliding in the primate group (human, c
