Sea turtle tornovirus 1 is a single stranded DNA virus that was isolated from a turtle with fibropapillomatosis in 2009.[1]
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.
Taxonomy
The final classification of this virus has yet to be decided.
It has a low level of homology to the Circovirus chicken anemia virus.
