| Summary: | Transposable elements (TEs) or transposons are thought to play roles in animal physiological processes, such as germline, early embryonic, and brain development, as well as aging. However, their roles have not been systematically investigated through experimental studies. In this study, we created a catalog of genes directly involved in replication, excision, or integration of transposon-coding DNA, which we refer to as transposon DNA processing genes (TDPGs). Specifically, to bridge the gap to experimental studies, we sought potentially functional TDPGs which maintain intact open reading frames and the amino acids at their catalytic cores on the latest long-read genome assembly of Caenorhabditis elegans , VC2010. Among 52 519 TE loci, we identified 145 potentially functional TDPGs encoded in long terminal repeat elements, long interspersed nuclear elements, terminal inverted repeat elements, Helitrons, and Mavericks/Polintons. Our TDPG catalog, which contains a feasible number of genes, allows for the experimental manipulation of TE mobility in vivo , regardless of whether the TEs are autonomous or non-autonomous, thereby potentially promoting the study of the physiological functions of TE mobility. |
