principle

Though it accounts a small ratio in the cell space, mitochondria possess about 10% to 15% proteins encoded by nuclear genes in eukaryotic organisms. These proteins are synthesized in cytosol and then recognized by the membrane receptors of mitochondria. Translocases in the outer and inner membrane of mitochondria mediate the import and intra-mitochondrial sorting of these proteins. ATP is used as an energy source; Chaperones and auxiliary factors assist in folding and assembly of mitochondrial proteins into their native, three-dimensional structures. 　　As shown in the figure above, beta-barrel outer-membrane proteins (dark green), precursor proteins (brown) with positively charged amino-terminal presequences and multispanning inner-membrane proteins (blue) with internal targeting signals are recognized by specific receptors of the outer mitochondrial membrane (TOM) translocases Tom20, Tom22 and/or Tom70. The precursor proteins are then translocated through a small Tom proteins of the TOM complex, Tom40 pore, which the TOM complex contains two or three.
