Protein interaction data exists in a number of repositories. Each repository has its own data format, molecule identifier and supplementary information. Michigan Molecular Interactions (MiMI) assists scientists searching through this overwhelming amount of protein interaction data. MiMI gathers data from well-known protein interaction databases and deep-merges the information. Utilizing an identity function, molecules that may have different identifiers but represent the same real-world object are merged. Thus, MiMI allows the users to retrieve information from many different databases at once, highlighting complementary and contradictory information. To help scientists judge the usefulness of a piece of data, MiMI tracks the provenance of all data.

MiMI data can be accessed in many different ways:

• through a "google-like" search interface
• through a form-based attribute specific search interface
• by pointing and clicking in a graphical visualizer such as Cytoscape
• through an experimental natural language query interface, NaLIX
• through an XQuery expression that can express arbitrarily complex queries over the data
