  • Listed are all proteins that were isolated at least twice as fusion proteins in the yeast two-hybrid screen with one of regions a–e as bait.

  • a Listed is the smallest fragment isolated that interacts with Prp8. Given in parentheses is the number of amino acids in the respective full-length protein.

  • b A frameshift is required to translate these codons (+1 in two clones and −1 in the third). It has previously been reported that frameshift events are selected for in the yeast two-hybrid screen, when viability depends on it (Fromont-Racine et al. 1997).

  • c Bmh1 and Bmh 2 are >90% identical.
