Abstract

Members of the tristetraprolin (TTP) family of CCCH tandem zinc finger proteins can bind directly to AU-rich elements in mRNAs and promote transcript deadenylation and decay. The yeast Schizosaccharomyces pombe expresses a single TTP family member, Zfs1p. In this study, we identified probable Zfs1p target mRNAs by comparing transcript levels in wild-type yeast and zfs1Δ mutants, using deep sequencing and microarray approaches. We also used direct RNA sequencing to determine polyadenylation site locations and to confirm the presence of potential Zfs1p target sequences within the target mRNA. These studies identified a set of transcripts containing potential Zfs1p binding sites that accumulated significantly in the zfs1Δ mutants; a subset of these transcripts decayed more slowly in the zfs1Δ mutants and bound directly to Zfs1p in coimmunoprecipitation assays. One apparent direct target encodes the transcription factor Cbf12p, which is known to increase cell-cell adhesion and flocculation when overexpressed. Studies of zfs1Δ cbf12Δ double mutants demonstrated that the increased flocculation seen in zfs1Δ mutants is due, at least in part, to a direct effect on the turnover of cbf12 mRNA. These data suggest that Zfs1p can both directly and indirectly regulate the levels of transcripts involved in cell-cell adhesion in this species.

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The only other fungus with a functionally described Cth2 ortholog, S. pombe, displays no transcriptional alterations of its iron homeostasis genes when this gene is deleted.

    “The only other fungus with a functionally described Cth2 ortholog, Schizosaccharomyces pombe, also displays no transcriptional alterations of its iron homeostasis genes when this gene is deleted (46, 47).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
