We have investigated the cleavages at the flavivirus capsid-prM protein junction in vitro. When expressed in the absence of the flavivirus proteinase, capsid and prM, which are separated by an internal signal sequence, exist as a membrane-spanning precursor protein. Here we show the induction of posttranslational signal peptidase cleavage of prM by trypsin cleavage of a cytoplasmic region of this precursor protein.
我们在体外研究了黄病毒衣壳蛋白与prM蛋白连接处的切割情况。当在没有黄病毒蛋白酶的情况下表达时,由内部信号序列分隔的衣壳蛋白和prM蛋白以跨膜前体蛋白的形式存在。在此我们展示了通过胰蛋白酶切割该前体蛋白的细胞质区域来诱导prM蛋白进行翻译后信号肽酶切割。
