Abstract: Proto2-3_CS1 is a very young family of non-LTR retrotransposons present in the annelid genome. It belongs to a novel clade of metazoan non-LTR retrotransposons called Proto2. This clade includes families of non-LTR retrotransposons present in the hydra (from Proto2-1_HM to Proto2-5_HM), annelid (from Proto2-1_CS1 to Proto2-8_CS1), hemichordate (Proto2-1_SK) and amphioxus (Proto2-1_BF) genomes. A model Proto2 non-LTR retrotransposon is ~4.3 kb long, contains two ORFs; its 3' terminus is composed of microsatellites; usually there is no target site duplications generated upon retrotransposition of Proto2 elements. ORF1 codes for a protein conserved in Proto2 elements from all species mentioned above. ORF2 codes for a protein composed from the AP endonuclease and reverse transcriptase domains. It appears that the Proto2 clade is a clade ancestral to the RTE and RTEX clades.
