ATP-dependent RNA helicase of the SFI superfamily; involved in nonsense mediated mRNA decay; required for efficient translation termination at nonsense codons and targeting of NMD substrates to P-bodies; binds to the small ribosomal subunit via an interaction with Rps26; forms cytoplasmic foci upon DNA replication stress

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.

Evidence against a direct role for the Upf proteins in frameshifting or nonsense codon readthrough.
The Upf proteins are essential for nonsense-mediated mRNA decay (NMD). They have also been implicated in the modulation of translational fidelity at viral frameshift signals and premature termination codons. How these factors function in both mRNA turnover and translational control remains unclear. In this study, mono- and bicistronic reporter systems were used in the yeast Saccharomyces cerevisae to differentiate between ... [more]
