Distribution of estrogen sulfotransferase genes in tunas and their relatives.

ABSTRACT:

Objective

Estrogen sulfotransferase is an enzyme involved in the inactivation of estrogen, and the encoding gene, sult1st6, is widely conserved among animal species. Recently, it was reported that a paralog of the estrogen sulfotransferase gene is paternally inherited in Pacific bluefin tuna (Thunnus orientalis), suggesting that this gene, sult1st6y, may be involved in sex determination or differentiation of Thunnus species as a suppressor of feminization. However, current knowledge on fish sult1st6 is still limited. This study aims to update the previous findings by thoroughly examining the distribution of sult1st6 in tuna (the species of tribe Thunnini) and their relatives (the species of family Scombridae).

Results

Based on a survey of the sult1st6 loci in the available c
