I want to analyze the databases of Protein Protein Interaction which are open source and freely available. I have
gone through the paper which is " An evaluation of human protein-protein interaction data in the public domain" by
Suresh Mathivanan, Balamurugan Periaswamy, TKB Gandhi. They have analyzed different freely available datasets which are MINT , INTACT , HPRD , BIND, DIP , MIPS , PDZBase , and Reactome. The links of the available databases are mentioned in the paper but there is a list of databases available in it. They havent mentioned which kind of database they are using for analysis. Can any one provide a better source from where i can download This open source databases for analysis.
