cDNA sequence and chromosomal localization of the NDUFS8 human gene coding for the 23 kDa subunit of the mitochondrial complex I.
We have sequenced the cDNA for the 23 kDa subunit of the human mitochondrial respiratory complex I. The deduced protein consists of 210 amino acids (Mr = 23705 Da) with a 34 amino acid N terminus presumably acting as a presequence for mitochondrial import. The predicted mature protein (Mr = 20290 Da) is 92% identical to the bovine mitochondrial subunit and 72% to the Rhodobacter capsulatus NUOI counterpart. Two clusters of four cysteine residues are conserved among these proteins. The gene (NDUFS8) coding for the human subunit has been mapped to chromosome 11q13.
