Abstract

Reactive oxygen species and free radicals that are produced during normal metabolism can potentially damage cellular macromolecules. Defenses against such damage include a number of antioxidant enzymes that specifically target the removal or dismutation of the reactive agent. We report here the isolation and regional mapping of a human gene, TDPX1, that encodes an enzyme homologous to a yeast thioredoxin-dependent peroxide reductase (thioredoxin peroxidase, TPX). The human TDPX1 coding sequence was determined from the product of a polymerase chain reaction (PCR) amplification of human cDNA. Based on PCR analysis of DNA from a human/rodent somatic cell hybrid panel, the TDPX1 locus was assigned to chromosome 13. Further localization of the locus to 13q12 was accomplished by fluorescence in situ hybridization analysis, using as a probe DNA from a yeast artificial chromosome (YAC) that contains the TDPX1 gene. It was also determined by PCR analysis of various YACs that the TDPX1 locus is in the region of the dinucleotide repeat markers D13S289 and D13S290. This regional mapping localizes the TDPX1 gene to a genomic region recently shown to contain the breast cancer susceptibility gene BRCA2 and a gene associated with a form of muscular dystrophy. Oxygen radical metabolism has been hypothesized to be important for cancer, muscular dystrophy, and other disorders, so TDPX1 should be considered a candidate gene for these diseases.
