Abstract

Although most tissues in an organism are genetically identical, the biochemistry of each is optimized to fulfill its unique physiological roles, with important consequences for human health and disease. Each tissue's unique physiology requires tightly regulated gene and protein expression coordinated by specialized, phosphorylation-dependent intracellular signaling. To better understand the role of phosphorylation in maintenance of physiological differences among tissues, we performed proteomic and phosphoproteomic characterizations of nine mouse tissues. We identified 12,039 proteins, including 6296 phosphoproteins harboring nearly 36,000 phosphorylation sites. Comparing protein abundances and phosphorylation levels revealed specialized, interconnected phosphorylation networks within each tissue while suggesting that many proteins are regulated by phosphorylation independently of their expression. Our data suggest that the "typical" phosphoprotein is widely expressed yet displays variable, often tissue-specific phosphorylation that tunes protein activity to the specific needs of each tissue. We offer this dataset as an online resource for the biological research community.

  • S239 was identified as an in vivo ATXN1 phosphorylation site in multiple tissues, including brain, by mass-spectrometry analysis.

    “One of these sites is serine 239 (S239), which was identified as an in vivo ATXN1 phosphorylation site in multiple tissues, including brain, by mass-spectrometry analysis (Vierra-Green et al., 2005; Huttlin et al., 2010).”

    From Polyglutamine Disease Toxicity Is Regulated by Nemo-like Kinase in Spinocerebellar Ataxia Type 1 (2013) · cites this paper as Huttlin et al., 2010

    The Experimental Procedures describe LC-MS/MS analysis of phosphopeptides from nine mouse organs, including brain, and the Results discuss phosphorylation across tissues. But our copy does not identify ATXN1 S239 or say that this site was found in multiple tissues; searches for ATXN1, ataxin-1, and S239 found no matching passage. (LLM, conf=0.72)

  • In SCA1, several phosphorylation sites have been identified in mouse brain in vivo including S776 and S239.

    “In SCA1, several phosphorylation sites have been identified so far in mouse brain in vivo including S776 and S239 (Emamian et al., 2003; Vierra-Green et al., 2005; Huttlin et al., 2010).”

    From Polyglutamine Disease Toxicity Is Regulated by Nemo-like Kinase in Spinocerebellar Ataxia Type 1 (2013) · cites this paper as Huttlin et al., 2010

    The Results section on tissue distribution reports phosphorylation sites in mouse brain, but the passages from our copy do not identify SCA1/ataxin-1 sites S776 or S239. Searches for those site numbers, ataxin-1/Atxn1, and spinocerebellar ataxia found no passage addressing the specific claim; page numbers were not provided. (LLM, conf=0.72)

    Experimental — accuracy not yet measured
  • Significantly higher numbers of identified proteins were so far only achieved by combining multiple diverse cell lines or tissues in one analysis, or by investing weeks of measurement for single samples.

    “Significantly higher numbers of identified proteins were so far only achieved by combining multiple diverse cell lines or tissues in one analysis (11), or by investing weeks of measurement for single samples (12, 13).”
  • The dataset was filtered to an MS2 spectra assignment false discovery rate of smaller than 1% at the protein level, using probabilities from linear discrimination scores.

    “Linear discrimination scores were used to assign probabilities to each MS2 spectrum for being assigned correctly and these probabilities were further used to filter the dataset with an MS2 spectra assignment FDR of smaller than a 1% at the protein level58.”

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.
