| Abstract: | All but one of the mitochondrial respiratory complexes are composed of products of both the mitochondrial and the nuclear genomes. The recent isolation of cDNAs for several nuclear-encoded respiratory proteins reveals that some of them are present in at least two forms. Although some of these forms are traditional in differing somewhat in amino acid sequence, a new class, termed silent isoforms, differs in the presequence but contains identical processed proteins. What are the roles of tissue isoforms in oxidative metabolism? |
