The major secretory product of the thyroid is a pro\u2010hormone, T<jats:sub>4<\/jats:sub>, which is activated in peripheral tissues by outer ring deiodination to T<jats:sub>3<\/jats:sub>. We have isolated from rainbow trout testis, a full length cDNA encoding type II iodothyronine deiodinase (rtD2). The cDNA was 2410 nucleotides long and coded for a polypeptide of 264 amino acids including a selenocysteine residue. The predicted molecular weight of rtD2 was 29.3 kDa and the isoelectric point 8.71. The deduced amino acids sequence showed 80% identity with <jats:italic>Fundulus heteroclitus<\/jats:italic> D2 (fhD2) but only 68\u201369% identity with rat, mouse, and human D2. The 3\u2032 UTR contained a putative selenocysteine insertion sequence (SECIS) similar to that described in human cDNA. The rtD2 gene was isolated and the gene structure was similar to that described in human with two exons separated by a large intron. We studied rtD2 gene expression by Northern blot analysis using total RNA extracted from testis, ovary, and other tissues. We found a high expression of a 3 kb transcript in liver and in gonads. A lower expression was also detected in posterior kidney. In testis, rtD2 mRNA expression was dependent on spermatogenic stages: it increased at the onset of spermatogenesis. Our results show that the structural characteristics of the D2 protein and gene have been highly conserved during evolution. The rtD2 mRNA expression in the gonads suggests that rtD2 may be a key factor regulating local supply of active T<jats:sub>3<\/jats:sub> during rainbow trout gametogenesis. Mol. Reprod.
