Tombusvirus 3′ UTR is an important cis-regulatory region of the Tombus virus genome.[1]
Tomato bushy stunt virus is the prototype member of the family Tombusviridae. The genome of this virus is positive sense single stranded RNA. Replication occurs via a negative strand RNA intermediate. In addition to viral proteins p33 and the RNA-dependent RNA polymerase p92, and unknown host factors, conserved and structural regions within the 3′ untranslated region (3′ UTR) are important for regulating genome replication. This 3′ structural element contains a pseudoknot.[1][2]
Other non-coding RNA structures in Tombusvirus include the 5′ UTR and an internal replication element.[3]
