Structural heterogeneity and functional convergence of transposable elements.

ABSTRACT: Almost half the mammalian genomes consist of transposable elements (TEs) and their derivatives. The distribution density of TEs can be associated with genomic regions of chromosomal rearrangements in different mammalian species and with the genomic localization of protein-coding genes that differ in length and function. To evaluate these characteristics at the local genomic level, an analysis of the distribution of various TEs (retrotransposons and DNA transposons) was performed in three mammalian species (human, cattle, and domestic rabbit) in genes with different functions and chromosomal localizations and their flanking regions. In humans and rabbits, melanophilin (MLPH) and myostatin (MSTN) are syntenic, but not in cattle. In the latter, MLPH and the leptin receptor (LEPR) are syntenic
