Molecular and Functional Characterization of Thioredoxin 1 from Korean Rose Bitterling (Rhodeus uyekii).

ABSTRACT: Thioredoxin is a multifunctional antioxidant enzyme that belongs to the reductase family. In this study, we cloned and characterized thioredoxin 1 cDNA from the Korean rose bitterling Rhodeus uyekii (RuTrx). The full-length RuTrx cDNA consists of 674 bp with a 324 nt open reading frame (ORF) encoding a 107 aa protein. The deduced RuTrx amino acid sequence indicated a characteristic redox active site, (31)WCGPC(35). Pairwise alignment revealed RuTrx amino acid identity (55.1%-83.2%) with orthologs from various species of mammalia, amphibia, fish and bird. Phylogenetic analysis was conducted to determine the evolutionary position of RuTrx. Expression analysis showed that RuTrx transcripts were present in all of the tissues examined, and was high in the hepatopancreas of R. uyekii. During ear
