Identification and functional analysis of mitochondrial complex I assembly factor homologues in C. elegans.

摘要
The biogenesis of mitochondrial NADH:ubiquinone oxidoreductase (complex I) requires several assembly chaperones. These so-called complex I assembly factors have emerged as a new class of human disease genes. Here, we identified putative assembly factor homologues in Caenorhabditis elegans. We demonstrate that two candidates (C50B8.3/NUAF-1, homologue of NDUFAF1 and R07H5.3/NUAF-3, homologue of NDUFAF3) clearly affect complex I function. Assembly factor deficient worms were shorter, showed a diminished brood size and displayed reduced fat content. Our results suggest that mitochondrial complex I biogenesis is evolutionarily conserved. Moreover, Caenorhabditis elegans appears to be a promising model organism to study assembly factor related human diseases.
