A database of mammalian mitochondrial localisation evidence, phenotypes and diseases
Many other genes will not be in these lists but may encode a protein that has some experimental evidence for mitochondrial localisation. These can be searched for on the 'Localisation Evidence' data category page. These are not necessarily non-mitochodrial that have been identified due to contamination. If a protein is low abundance, tissue specific or expression specific this may result in it being missed by a majority of studies. In addition many mitochondrial proteins are membrane bound and these are notoriously difficult to identify by mass spectrometry as most purification procedures are biased towards extracting soluble proteins.
