Report of a chimeric origin of transposable elements in a bovine-coding gene

L. M. Almeida, Amaral, M. E. J., Silva, I. T., Silva, Jr., W. A., Riggs, P. K., and Carareto, C. M., Report of a chimeric origin of transposable elements in a bovine-coding gene, vol. 7, pp. 107-116, 2008.

Despite the wide distribution of transposable elements (TEs) in mammalian genomes, part of their evolutionary significance remains to be discovered. Today there is a substantial amount of evidence showing that TEs are involved in the generation of new exons in different species. In the present study, we searched 22,805 genes and reported the occurrence of TE-cassettes in coding sequences of 542 cow genes using the RepeatMasker program.
