Abstract

The covalent attachment of ubiquitin to proteins regulates numerous processes in eukaryotic cells. Here we report the identification of 753 unique lysine ubiquitylation sites on 471 proteins using higher-energy collisional dissociation on the LTQ Orbitrap Velos. In total 5756 putative ubiquitin substrates were identified. Lysine residues targeted by the ubiquitin-ligase system show no unique sequence feature. Surface accessible lysine residues located in ordered secondary regions, surrounded by smaller and positively charged amino acids are preferred sites of ubiquitylation. Lysine ubiquitylation shows promiscuity at the site level, as evidenced by low evolutionary conservation of ubiquitylation sites across eukaryotic species. Among lysine modifications a significant overlap (20%) between ubiquitylation and acetylation at site level highlights extensive competitive crosstalk among these modifications. This site-specific crosstalk is not prevalent among cell cycle ubiquitylations. Between SUMOylation and ubiquitylation the preferred interaction is through mixed-chain conjugation. Overall these data provide novel insights into the site-specific selection and regulatory function of lysine ubiquitylation.

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.
