Human Proteinpedia
Human Proteinpedia is a portal for sharing and integration of human proteomic data. It allows research laboratories to contribute and maintain protein annotations. Human Protein Reference Database (HPRD) integrates data, that is deposited in Human Proteinpedia along with the existing literature curated information at the context of an individual protein. In essence, researchers can add new data to HPRD by registering to Human Proteinpedia. The data deposited in Human Proteinpedia is freely available for download. Emphasizing the importance of proteomics data disposition to public repositories, "Nature Methods" recommends Human Proteinpedia in their editorial. More than 70 labs participate  in this effort. Data types. Data pertaining to post-translational modifications, protein–protein interactions, tissue expression, expression in cell lines, subcellular localization and enzyme substrate relationships can be submitted to Human Proteinpedia. Experimental platforms. Protein annotations present in Human Proteinpedia are derived from a number of platforms such as This portal that allows adding of protein information was developed as a collaborative effort between the laboratory of Dr. Akhilesh Pandey at Johns Hopkins University and the Institute of Bioinformatics FAQs. Any investigator who fulfills the following criteria can contribute data: i) provides experimentally derived data, and, ii) is willing to  share data, and, iii) is willing to be listed as the 'contributor' of the data Anonymous contributions are not allowed. Contributor details should be clearly presented while contributing data. Predictions of any type are not allowed. Contributed data should be derived experimentally and should be accompanied with experimental evidence. The data are not subjected to peer review and the actual experimental data (raw or processed) should be provided. In cases where a given entry is documented as erroneous, we will consult with the contributing group(s) about deleting the entry.
