What is it about?
We analyze all known genomes that have been properly annotated to look for syntenic sequences and check if their evolution on gene duplications has changed their sequence for further roles as well as the sequences linked to this protein. Surprisingly, avian genomes lack this essential protein. Furthermore, mammalian evolution shows two different pathways for this protein leading to open questions about the functionality of the second sequence of fibrillarin.

Why is it important?
This is relevant in several fields. Fibrillarin is required for Viral progression in plants and plays several roles in viral infection in humans and animals. Furthermore, the expression of fibrillarin and fibrillarin is different and increases in different types of cancers. It is currently unknown many of the aspects that this protein may play in all these illnesses, but its role is far from well understood.
