Structural organization and chromosomal localization of the human nuclear gene (NDUFV2) for the 24-kDa iron-sulfur subunit of complex I in mitochondrial respiratory chain.

The structural organization of the entire human nuclear encoded gene for the 24-kDa iron-sulfur subunit of mitochondrial NADH-ubiquinone oxidoreductase (Complex I) and its chromosomal localization were determined. The gene contains 8 exons spanning 31.5 kb. The 5' flanking region sequenced lacks typical CAAT and TATA boxes but contains three putative GC boxes and there is one GC box at the beginning of the first intron. The sequences matching completely with the NRF-1 binding site and Mt elements were not identified in the flanking region. This gene was assigned to human chromosome 18 at region p11.3, by fluorescent in situ hybridization.
