Sharing experimental data is important for the scientific community, for example, to validate and reuse the data. In Japan, the Database Integration Coordination Program has been promoted to share the life science data. We have joined this program and developed a new repository for MS raw and processed data to share the proteomics data. However, the processed data by submitters are generally in a wide variety of qualities because each experiment has been analyzed under the different criteria. To ensure the quality of processed data, we have developed our own workflow for reanalysis of the deposited raw data, and the results are stored in the curated database. Here, we introduce the current status of our developing system “jPOST,” Japan ProteOme STandard repository/database.
