Epsilonretrovirus

The Epsilonretroviren is a genus within the family of retroviruses. They belong to the simple retroviruses. Epsilonretroviren infect fish. Some cause tumors, such as the Walleye dermal sarcoma virus ( Walleye, ie Walleye ).

The genomic structure of the Epsilonretroviren is unique among retroviruses because they upstream of gag have an ORF, which is designated as orf -C. In addition, they are the only known retroviruses using a histidyl - tRNA for priming of DNA synthesis to the start of the first strand. Another ORF ORF -A, coding for a retroviral cyclin heretofore found only in Epsilonretroviren.
