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.

PF20981AAR2 N-terminal domain (AAR2_1st)AAR2 N-terminal domainThis family consists of several eukaryotic AAR2-like proteins. The yeast protein AAR2 is involved in splicing pre-mRNA of the a1 cistron and other genes that are important for cell growth [1]. This entry represents the N-terminal Ig-like domain.Domain
