Abstract

The mitochondrial protein entry gate, the TOM complex, undergoes a dynamic conversion between the fully assembled trimer and the dimer lacking Tom22. Mitochondrial porin, Por1, regulates the trimer assembly by chaperoning newly imported Tom22 and dimer-trimer dependent functions of the TOM complex together with Tom6.
