    Abstract:

    Subunit Vb of mammalian cytochrome c oxidase (COX; EC 1.9.3.1) is encoded by a nuclear gene and assembled with the other 12 COX subunits encoded in both mitochondrial and nuclear DNA. We have cloned the gene for human COX subunit Vb (COX5B) and determined the exon-intron structure by both hybridization analysis and DNA sequencing. The gene contains five exons and four introns; the four coding exons span a region of approximately 2.4 kb. The 5' end of the COX5B gene is GC-rich and contains many HpaII sites. Genomic Southern blot analysis of human DNA probed with the human COX Vb cDNA identified eight restriction fragments containing COX Vb-related sequences that were mapped to different chromosomes with panels of human x Chinese hamster somatic cell hybrids. Because only one of these fragments hybridized with a 210-bp probe from intron 4, we conclude that there is a single expressed gene for COX subunit Vb in the human genome. We have mapped this gene to chromosome 2, region cen-q13.
