PeptideAtlas

PeptideAtlas is a multi-organism, publicly accessible compendium of peptides identified in a
large set of tandem mass spectrometry proteomics experiments. Mass spectrometer output files are
collected for human, mouse, yeast, and several other organisms, and searched using the latest search
engines and protein sequences. All results of sequence and spectral library searching are subsequently
processed through the  Trans
Proteomic Pipeline to derive a probability of correct identification for all results in a
uniform manner to insure a high quality database, along with false discovery rates at the whole atlas
level. Results may be queried and browsed at the PeptideAtlas web site. The raw data, search results,
and full builds can also be downloaded for other uses.
