About

The Human Ubiquitination Proteome PeptideAtlas provides a compendium of results from uniformly reprocessed mass spectrometry proteomics datasets.

Available datasets of Human Ubiquitination Proteome samples were reprocessed from the raw files using the Trans-Proteomic Pipeline suite of tools.

Chromosome Summary

Column descriptions ▲

Entries: Number of entries in each chromosome
Canonical: Proteins seen with 2 distinct, uniquely mapping peptides
Uncertain: Proteins with some evidence that is not sufficient for canonical status
Redundant: Proteins that have peptides that map to them, but not uniquely and thus not needed to explain the observed peptides
Not Observed: No detections at all in PeptideAtlas above our very stringent threshold

Publications

A publication describing the Human Ubiquitination Proteome PeptideAtlas build is in progress.

Download

Below are individual Human Ubiquitination Proteome PeptideAtlas builds available for download in various flat file formats. Note that not all files contain all information from the build. A build subtitled "PSM FDR=0.002" denotes a PSM FDR threshold of 0.002 (0.2%) is applied to every sample in the build.
