Predicted to enable RNA helicase activity and identical protein binding activity. Predicted to be involved in spliceosome conformational change to release U4 (or U4atac) and U1 (or U11). Predicted to be located in nucleoplasm. Predicted to be part of spliceosomal complex and spliceosomal snRNP complex. Human ortholog(s) of this gene implicated in retinitis pigmentosa and retinitis pigmentosa 33. Orthologous to human SNRNP200 (small nuclear ribonucleoprotein U5 subunit 200).
