Abstract

PPR proteins are a family of ubiquitous RNA-binding factors, found in all the Eukaryotic lineages, and are particularly numerous in higher plants. According to recent bioinformatic analyses, yeast genomes encode from 10 (in S. pombe) to 15 (in S. cerevisiae) PPR proteins. All of these proteins are mitochondrial and very often interact with the mitochondrial membrane. Apart from the general factors, RNA polymerase and RNase P, most yeast PPR proteins are involved in the stability and/or translation of mitochondrially encoded RNAs. At present, some information concerning the target RNA(s) of most of these proteins is available, the next challenge will be to refine our understanding of the function of the proteins and to resolve the yeast PPR-RNA-binding code, which might differ significantly from the plant PPR code.

  • Thirteen putative C. albicans PPR proteins were identified using the SCIPHER algorithm by Lipinski et al. (2011), and 9 of them show clear orthology to well-characterized PPR proteins of S. cerevisiae and S. pombe.

    “Thirteen putative C. albicans PPR proteins were identified using the SCIPHER algorithm by Lipinski et al. (2011), and 9 of them show clear orthology to well-characterized PPR proteins of S. cerevisiae and S. pombe (CaAep3p, CaAep2p, CaDmr1p, CaRpo41p, CaPet111p, CaPet309p, CaAtp22p, CaRmd9p, and CaCbp1p) (Kühl et al. 2011; Lipinski et al. 2011; Herbert et al. 2013).”
  • The SCIPHER algorithm tailored for the identification of new members of this family in yeasts does not recognize numerous μ-helical repeats as statistically significant PPR motifs.

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.
