The cancer antigen atlas (caAtlas) is a comprehensive resource for the selection and prioritization of peptides for immunogenicity testing and cancer immunotherapy development. It was built upon publicly available mass spectrometry (MS)-based human immunopeptidomic datasets from 309 cancer samples covering nine cancer types and 225 non-cancerous samples. Standardized analysis of the 51.6 million MS/MS spectra from these datasets identified 5.8 million peptide-spectrum matches corresponding to 365,267 peptides, including 93,709 modified peptides and 324,772 non-modified peptides. Further analysis of these data provided evidence for tumor specific-presentation of post translationally modified antigens, cancer testis antigens and cancer type-specific tumor associated antigens. Systematic analysis of the 100,000 most frequently reported mutations in the International Cancer Genome Consortium (ICGC) database finds immunopeptidomic evidence for only a single recurrent mutation (TP53 T125M). caAtlas makes all these data together with annotated MS/MS spectra supporting each individual antigen identification in an easily browsable web portal.
