Abstract:We have isolated a novel cDNA sequence from a male mouse liver library. It consists of an open reading frame containing no stop codon of 1348 bp which share 98 % similarity with the cytochrome P450 2b10 followed by 95 nucleotides sharing 88 % identity with the mouse NADPH cytochrome P450 oxidoreductase. Proteins are encoded by the opposite DNA strands. Genomic amplification excludes a library artefact or a de novo recombination event. RT-PCR analyses revealed expression of this clone in the liver of male and female mice as well as in kidney, lung and intestine. This cDNA was not, however, induced by phenobarbital. Preliminary results indicate that this cDNA could span more than 2.5 kb. This study is the first description of a cytochrome P450 cDNA sequence encoding part of both a cytochrome P450 and the NADPH cytochrome P450 oxidoreductase in mammalian liver.
