''Sea turtle tornovirus 1'' is a single stranded DNA virus that was isolated from a turtle with fibropapillomatosis in 2009.〔Ng TF, Manire C, Borrowman K, Langer T, Ehrhart L, Breitbart M (2009) Discovery of a novel single-stranded DNA virus from a sea turtle fibropapilloma by using viral metagenomics. J Virol 83(6):2500-2509〕 ==Virology==
The genome is circular and ~1.8 kilobases in length with a G+C content of ~50%. It has at least three open reading frames (ORF 1, 2, 3) and two others (ORF 4 and 5) may also be present. The genome is of negative polarity. ORF 1 possesses a putative nuclear localization signal at its N terminal. ORF 2 has some homology to the viral protein 2 of chicken anaemia virus. ORF 3 has no homology to any known protein. Similarly neither ORF 4 or 5 have any homology with any known protein. The functions of these proteins is not known. A TATA box (sequence - TATAAA) and a poly adenosine signal (sequence - AATAAA) are present in the genome.
