This domain is found in eukaryotes, and is about 20 amino acids in length. It is found associated with Pfam:PF10597, Pfam:PF10596, Pfam:PF10598, Pfam:PF08083, Pfam:PF08082, Pfam:PF01398, Pfam:PF08084. There is a conserved LILR sequence motif. The domain is a selenomethionine domain in a subunit of the spliceosome. The function of PRP8 domain IV is believed to be interaction with the splicosomal core.	Domain
