. Genetic and structural characterization of the human mitochondrial inner membrane translocase. J Mol Biol. 1999;289:69-82 pubmed
..Both TIM complexes display a native molecular mass of 110 kDa. We suggest that the structural organization of TIM23.17 preprotein translocases is conserved from low to high eukaryotes. ..

. QIL1 is a novel mitochondrial protein required for MICOS complex stability and cristae morphology. elife. 2015;4: pubmed publisher
..Collectively, our work uncovers a previously unrecognized subunit of the MICOS complex, necessary for CJ integrity, cristae morphology, and mitochondrial function and provides a resource for further analysis of MICOS architecture. ..

..These assays thus demonstrated the 18.1, 21.9, and 45 kDa proteins to be the translocator components of the rat mitochondrial inner membrane and, therefore, the functional homologues of Tim17, Tim23, and Tim44, respectively. ..

..These results suggest that the precursor is first targeted to the inner membrane component DeltaPsi-dependently, then transferred to the Tim system consisting of Tim23-Tim17, and finally imported into the matrix. ..
