We report the cloning of an ovine thioredoxin cDNA. The clone was isol
ated from a bovine leukemia virus-infected cell line (FLK) cDNA librar
y cloned in the lambda gt11 vector. The clone encodes the full length
thioredoxin protein made of 105 amino acids with 92 and 83% identity t
o published sequences of human and mouse thioredoxin, respectively.
