Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Prp45 affects Prp22 partition in spliceosomal complexes and splicing efficiency of non-consensus substrates.

Human transcription co-regulator SNW1/SKIP is implicated in the regulation of both transcription elongation and alternative splicing. Prp45, the SNW/SKIP ortholog in yeast, is assumed to be essential for pre-mRNA processing. Here, we characterize prp45(1-169), a temperature sensitive allele of PRP45, which at permissive temperature elicits cell division defects and hypersensitivity to microtubule inhibitors. Using a synthetic lethality screen, we found ... [more]
