This domain is found in spliceosomal RNA helicase Brr2. Brr2 is required for the assembly of a catalytically active spliceosome on a messenger RNA precursor. The domain is found in the N-terminal region and is non-canonically PWI-like. The PWI-like domain is thought to be involved in protein-protein interactions [1].	Domain
