Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Publication

CEF1/CDC5 alleles modulate transitions between catalytic conformations of the spliceosome.

Query CC, Konarska MM

Conformational change within the spliceosome is required between the first and second catalytic steps of pre-mRNA splicing. A prior genetic screen for suppressors of an intron mutant that stalls between the two steps yielded both prp8 and non-prp8 alleles that suppressed second-step splicing defects. We have now identified the strongest non-prp8 suppressors as alleles of the NTC (Prp19 complex) component, ... [more]

Additional Notes

the cef1-V36R allele restored viability of a strain carrying U6-A51C alleles and growth defects due to U6-G52C and U6-A59C
the combination of U6-U57C (first-step allele) with the second-step cef1 alleles resulted in rescue of the ts phenotype of U6-U57C
