This domain is found at the C-terminal end of U4/U6 and U4/U5/U6- small nuclear ribonucleoprotein Prp3, part of the tri-RNA complex that form the spliceosome. Prp3 plays a key role in the recognition of the snRNA duplex. This binding domain, highly conserved among eukaryotes, interacts with the 3' end of U6 snRNA. It adopts a ferredoxin-like fold, showing a five-stranded mixed beta-sheet with three alpha-helices, two of them running parallel to the beta-strands on one side of the sheet and one on the other. This fold is extended with a long beta-hairpin, an extra beta-strand, an helix and a final loop at the C terminus. It is located C-terminal to Pfam:PF08572 [1-4].	Domain
