What does PRIDE contain?
What does PRIDE store?
PRIDE aims to represent the submitter's original view of the data. PRIDE stores:
- Processed identification results: peptide and protein identifications, including post-translational modifications (PTMs);
- Mass spectrometer output files: both raw data and peak list files;
- Quantification values: peptide and protein expression values (if available);
- Metadata: technical and biological metadata;
- Other files related to one submission: gel images, scripts, etc
Why do we need PRIDE?
Various journals in the field strongly support, and some even mandate, deposition of MS-based proteomics data into a public proteomics repository such as PRIDE (or others from the ProteomeXchange consortium). This enables researchers to understand, and potentially reproduce, experiments described in a particular publication. It also allows you to reanalyse mass spectra data as protein sequence databases and search-engine toolkits improve.
In addition, PRIDE provides proteomics data to other data resources such as UniProt.
