Abstract__ Retroviruses have evolved multiple strategies to direct the synthesis of a complex proteome from a single primary transcript. Their mechanisms are modulated by a breadth of virus-host interactions which are of significant fundamental interest because they ultimately affect the efficiency of virus replication and disease pathogenesis. Motifs located within the untranslated region UTR of the retroviral RNA have established roles in transcriptional trans-activation RNA packaging and genome reverse transcription and a growing literature has revealed a necessary role of the UTR in modulating the efficiency of viral protein synthesis. Examples include a 5 UTR post-transcriptional control element PCE present in at least eight retroviruses that interacts with cellular RNA helicase A to facilitate cap-dependent polyribosome association and 3 UTR constitutive transport element CTE of .
