pubmed:abstractText |
A cDNA clone coding for boar transition protein 2 (TNP 2) was isolated from a randomly primed cDNA library of boar testis. Sequence analysis revealed an open reading frame of 414 bp (corresponding to 138 amino acids), 33 bp of the 5' untranslated and about 300 bp of the 3' untranslated region. As compared to TNP 2 of mouse and rat, similarity with TNP 2 of the boar is approximately 70% at the nucleotide level and only about 40% on the basis of amino acid sequence. The similarity between boar and bull TNP2 is 77% and 64%, respectively. Northern blot experiments with RNA of different boar tissues and in situ hybridization on mature boar testis sections revealed testis-specific expression of the TNP 2 gene which is restricted to haploid germ cells. Hybridization experiments of boar TNP2 cDNA with testicular RNA of boar, bull, rat and mouse revealed decreasing intensities of the hybridization signals. With human testicular RNA no hybridization could be obtained.
