Due to the functions that estrogens play in the regulation of reproduction, development of the mammary gland, growth and differentiation of cells, estrogen receptors and their genes are considered candidates for the markers of production and functional traits in farm animals, including cattle. In the present study, on the basis of the sequences of the human, ovine, and porcine ER genes, available in the GenBank database, sets of PCR primers were designed and used to amplify the bovine ERa gene 5?-region. Seven overlapping fragments of the 5? region of the bovine ERa gene were amplified and then sequenced. Altogether, these fragments were composed in the 2853-bp sequence which was deposited in the GenBank database under accession no. AY340597. The sequenced fragment included the noncoding exons A, B, C, their putative promoters, and a part of the coding exon 1. A polymorphism within the 5? region of the bovine ERa gene ? A/G transition, which could be recognized with RFLP-BglI, lying upstream to the exon C, was identified for the first time using this sequence.
