UPSK RNA
RNA family
From Wikipedia, the free encyclopedia
The Upstream pseudoknot (UPSK) domain is an RNA element found in the turnip yellow mosaic virus, beet virus Q,[1] barley stripe mosaic virus[2] and tobacco mosaic virus,[3] which is thought to be needed for efficient transcription. Disruption of the pseudoknot structure gives rise to a 50% drop in transcription efficiency.[4] This element acts in conjunction with the Tymovirus/Pomovirus tRNA-like 3' UTR element to enhance translation.[5]
