A bstract : Most estrogen actions are mediated by two estrogen receptor subtypes (ERα and ERβ). While a single ERβ appears to be present in higher vertebrates, two forms of ERβ encoded by different genes have recently been isolated in some teleost fish species. We investigated whether this also applies to the hermaphrodite sparid sea bream ( Sparus auratus ) and cloned a second ERβ (sbERβ2) in this species. We have also compared the tissue distribution of the three receptors as yet identified in sea bream, designated sbERα, sbERβ1, and sbERβ2.
