Previous studies of norovirus polyprotein processing have yielded three major products following in vitro transcription and translation, representing the uncleaved 3ABCD, N-term and 2C proteins. In addition, this important observation also confirms for the first time that the JV 3C protease was active in cells transfected with capped RNA as the size of the V5/N-term indicated successful cleavage of the protein from the ORF1 polyprotein. Unlike similarly studied human noroviruses JV initially did not appear to express the N-terminal protein, presenting the possibility that the encoding RNA sequence had a regulatory function itself, most likely involved in translation initiation in an IRES-like manner. ./cache/cord-048471-7jszm1nd.txt ./txt/cord-048471-7jszm1nd.txt
