Import of preproteins into mitochondria requires transport machineries in both mitochondrial membranes that have been characterized in Saccharomyces cerevisiaeand Neurospora crassa. By cDNA analysis, we identified a human protein of 16 kDa with significant overall homology to the fungal mitochondrial import receptor Mom19, including the three typical characteristics: a hydrophobic N‐terminal segment, a tetratrico peptide motif in the middle and a negatively charged C‐terminus. The human Mom19 homolog is expressed in all tissues analyzed. When synthesized in vitro, the human Mom19 homolog is targeted to isolated yeast mitochondria and specifically associates with the outer membrane receptor complex, suggesting that indeed a mitochondrial import receptor was identified. |
