    Summary
    Enables RNA helicase activity. Contributes to second spliceosomal transesterification activity. Involved in generation of catalytic spliceosome for second transesterification step and spliceosomal complex disassembly. Part of U2-type catalytic step 2 spliceosome and U2-type post-spliceosomal complex. Orthologous to human DHX8 (DEAH-box helicase 8). [provided by Alliance of Genome Resources, Apr 2022]

    What's a GeneRIF?
    1. At the catalytic stage of splicing, suboptimal splice sites are repressed by the DEAH-box ATPases Prp16 and Prp22. study shows that these ATPases function further by enabling the spliceosome to search for and utilize alternative branch sites and 3' splice sites.
