Structural characteristics of the bovine leukemia virus genome: A mini review

open access: yesПищевые системы, 2023
Enzootic bovine leukemia is an infectious disease with a chronic course caused by an RNA‑containing virus of the genus Deltaretrovirus. Despite the implementation of various programs for the elimination of leukemia, the disease is still widespread on the

The bovine leukemia virus p34 is a transactivator protein. [PDF]

open access: yesThe EMBO Journal, 1987
Recombinant Moloney murine retroviruses containing the BLV post-envelope long open reading frame were constructed and transfected into the psi 2 packaging cell line. They were shown to encode and to express a 34-kd protein able to transactivate the BLV long terminal repeat-directed gene expression in the respective transfected cells.
