Cloning, structural organization and tissue-specific expression of the rabbit transferrin gene

We cloned the rabbit transferrin (rTf) cDNA and gene, and quantified the expression of the rTf gene at the RNA level in various organs. The tissue-specific pattern of expression of rTf gene is different to those in other species, with a high expression in mammary gland and kidney. The exon/intron structure of the rTf gene (17 exons/16 introns) is similar to those of transferrins from other species. The sequence of the rTf cDNA already published is corrected and lengthened in the 5' region, and a likely polymorphism is documented.
