In Vivo Addition of Poly(A) Tail and AU-Rich Sequences to the 3′ Terminus of the Sindbis Virus RNA Genome: a Novel 3′-End Repair Pathway

Abstract excerpt

Alphaviruses are mosquito-transmitted RNA viruses that cause important diseases in both humans and livestock. Sindbis virus (SIN), the type species of the alphavirus genus, carries a 11.7-kb positive-sense RNA genome which is capped at its 5' end and polyadenylated at its 3' end. The 3' nontranslated region (3'NTR) of the SIN genome carries many AU-rich motifs, including a 19-nucleotide (nt) conserved element...
