The Center for Molecular Medicine at Emory University maintains this human mitochondrial genome database, which offers information on Mitochondrial DNA Function Locations and Polypeptide Assignments as well as the relevant publication references. The database is initially searchable by gene, disease, and enzyme. Users can then refine their search by function, polymorphisms, or references (author, title, journal, year, or keyword). Users can also search the references directly via an Advanced Search. An additional resource at the site is a reference guide to mitomap tables featuring searchable (by keyword) information on specific mitochondrial DNA function locations and references. An opportunity to add publications to this database is available, if users find that pertinent papers have not been cited.
