Notes: In gray, protein identification obtained with a single hit. Those hits were validated by visual inspection. MS/MS data are reported in Supplementary Information. Mascot score (*) is reported for identifications which have not passed TPP validation, but were above Mascot threshold of 29 and for which manual validation was undertaken.
