    ..Even in vitro, the absence of the protein has little effect on splicing. On the basis of these observations, we suggest that a principal role of the U1A protein is to help fold or maintain U1 RNA in an active configuration. ..

    ..These data suggest that the loss of Luc7p disrupts U1 snRNP-CBC interaction, and that this interaction contributes to normal 5' splice site recognition. ..

    ..Mud2 mutational effects in the swm2Delta background paralleled those for mud1Delta. The requirements for Mud2 function are apparently more stringent when yeast cells lack TMG caps than when they lack Mud1 or Swm2.

    ..Instead, delays in cotranscriptional U5 snRNP and Prp19 recruitment and altered spliceosome formation in vitro suggest that Prp40 WW domains assist in late steps of spliceosome assembly. ..

    ..Mutants lacking yCBC were found to be defective in rRNA processing. Analysis of the yCBC deletion phenotype suggests that this is likely to be due to a defect in the splicing of a subset of ribosomal protein mRNA precursors. ..
