The MissingProteinPedia is a protein data and information sharing web system that aims to collate any relevant data ‘Missing proteins’ as defined by neXtProt. At its core is a schema-less database-driven web system allowing captures of all PE2-4 protein PubMed data, based on gene and protein including synonyms. The database also allows unpublished, preliminary or proprietary data (e.g., antibody, MS, cell biological and genetic studies) to be shared with collaborators via a protected interface.

MissingProteinPedia facilitates the Human Proteome Project (HPP) cross-disciplinary collaboration by providing a complimentary, unfiltered, lower stringency perspective to both the HPP metrics and guidelines approaches, enabling community evaluation and scrutiny. MissingProteinPedia incorporates text mining technology to fetch and search accumulated UniProt, GeneCards, GeneRifs, PubMed PE2-4 data. Besides, MissingProteinPedia summarizes publicly available MS data from PRIDE, GPMDB, ProteomicsDB and MaxQB for relevant PE2-4 proteins. It allows community administrators to curate information before web publication.

We encourage all visitors to browse and contribute to 'finding' these proteins by sharing any relevant information on them that we may have missed!
