The Upstream pseudoknot (UPSK) is an RNA element found in turnip yellow mosaic virus which is thought to be needed for efficient transcription. Disruption of the pseudoknot structure gives rise to a 50% drop in transcription efficiency.[1] This element acts in conjunction with the Tymovirus/Pomovirus tRNA-like 3' UTR element to enhance translation.[2]
