    Summary
    Contributes to second spliceosomal transesterification activity. Involved in generation of catalytic spliceosome for second transesterification step and nuclear mRNA surveillance. Part of U2-type post-spliceosomal complex; U4/U6 x U5 tri-snRNP complex; and U5 snRNP. Orthologous to human PRPF18 (pre-mRNA processing factor 18).

    1. Splicing factor Prp18p promotes genome-wide fidelity of consensus 3'-splice sites.
      Title: Splicing factor Prp18p promotes genome-wide fidelity of consensus 3'-splice sites.
    2. structure along with sequence comparisons among SRA1p orthologs and against authentic RNA recognition motif (RRM) proteins indicates that it is not an RRM domain but rather an all-helical protein with a fold more similar to the PRP18 splicing factor
      Title: The C-terminal domain of SRA1p has a fold more similar to PRP18 than to an RRM and does not directly bind to the SRA1 RNA STR7 region.
