CDNA Isolation and Expression of Nicotinamide Adenine Dinucleotide Phosphate-Dependent Cytochrome P450 Reductase Gene in the Chagas Disease Vector Triatoma infestans.

ABSTRACT: Pyrethroid resistance has been detected in Triatoma infestans (Hemiptera: Reduviidae), which was atributed to target site insensitivity and increased oxidative metabolism of the insecticide by cytochrome P450s. Nicotinamide adenine dinucleotide phosphate (NADPH) cytochrome P450 reductase (CPR) plays an essential role in transferring electrons from NADPH to the P450-substrate complex. In this study, the full length CPR cDNA of T. infestans was isolated and gene expression was determined by quantitative polymerase chain reaction. The open reading frame is 2,046 bp long, encoding a protein of 682 amino acids. Amino acid sequence analysis indicates that the T. infestans CPR and the putative Rhodnius prolixus and Triatoma dimidiata CPRs present conserved ligand-binding domains. Congruent with a
