abstractText | 1-Cys peroxiredoxin (1-cysPrx), a member of the peroxiredoxin family with a single conserved cysteine, is a unique antioxidant enzyme. We have generated mice in which the 1-cysPrx gene has been inactivated; they are viable and fertile. Mice have a highly related intronless gene (1-cysPrx-P1, GenBank accession number AF085220) with the same length of open reading frame (224 aa) as 1-cysPrx but located on a different chromosome. Since the product of this gene possibly could mimic 1-cysPrx function, we compared expression of 1-cysPrx and 1-cysPrx-P1 in mouse tissues by real-time polymerase chain reaction and Western blot. 1-cysPrx mRNA and protein were expressed in all mouse tissues that were examined with the highest expression level in lung. 1-cysPrx-P1 mRNA was expressed only in testis. In the 1-cysPrx 'knock-out' mouse, 1-cysPrx-P1 mRNA expression level was similar to the wild type but protein expression was not detected. Thus, mouse 1-cysPrx-P1 is an mRNA-expressed pseudogene that does not result in detectable protein in vivo. |
