Ciaccio PJ, Graves PE, Bourque DP, Glinsmann-Gibson B, Halpert JR. 1991. cDNA and deduced amino acid sequences of a dog liver cytochrome P450 of the IIIA gene subfamily. Biochimica Biophysica Acta 1088:319–322


A 1.96 kbp cDNA encoding a male Beagle dog liver cytochrome P-450 of 503 amino acid residues (Mr 57,636) has been isolated and sequenced. The deduced amino acid sequence is 79.8%, 69.3% and 74.1% identical to the P450IIIA forms human NF25, rat PCN1 and rabbit LM3c, respectively. The amino terminal sequence is identical to the first 28 residues of the dog P450IIIA form PBD-1. Southern blot analysis yields restriction patterns consistent with IIIA gene subfamily multiplicity.
