like fungi.

Inteins vary greatly, but many of the same intein-containing proteins are found in a number of species. For example, pre-mRNA processing factor 8 (Prp8) protein, instrumental in the spliceosome, has seven different intein insertion sites across eukaryotic species. Intein-containing Prp8 is most commonly found in fungi, but is also seen in Amoebozoa, Chlorophyta, Capsaspora,
