PRP45

FUN20, mRNA splicing protein PRP45, L000000638, YAL032C
Protein required for pre-mRNA splicing; associates with the spliceosome and interacts with splicing factors Prp22p and Prp46p; orthologous to human transcriptional coactivator SKIP and can activate transcription of a reporter gene
Saccharomyces cerevisiae (S288c)
PREY

CDC40

PRP17, SLT15, SLU4, L000000275, L000001921, YDR364C
Pre-mRNA splicing factor; important for catalytic step II of pre-mRNA splicing and plays a role in cell cycle progression; required for DNA synthesis during mitosis and meiosis; has WD repeats
Saccharomyces cerevisiae (S288c)

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.

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]
