Abstract: Troyka is a distinctive group of gypsy-like LTR retrotransposons. Troyka retrotransposons differ from canonical gypsy and other LTR retrotransposons by the length of target site duplications (3-bp in Troyka) and by the unusual 5'-CG and CG-3' termini of LTRs. The ~1600-aa polyprotein encoded by Troyka elements is composed of the aspartyl protease (pos. 350-400), reverse transcriptase (pos. 700-900), and integrase domains (pos. 1250-1400). The polyproteins encoded by different families of Troyka present in the cnidarian and amphioxus genomes are ~50% identical to each other. However, there proteins are only 20-30% identical to the pro, RT and INT domains encoded by canonical gypsy LTR retrotransposons. Troyka-1_NV is a very young family of Troyka LTR retrotransposons present in the cnidarian genome. Copies of Troyka-1_NV are flanked by ~99% identical LTRs.
