By using a translation assay in oocytes, a 17S RNA fraction coding for the interferon-induced (2'-5')oligo(A) synthetase was purified from human cells. A cDNA library was prepared by cloning in Escherichia coli plasmid pBR322 and screened by positive hybridization-translation in oocytes. A cDNA clone corresponding to the (2'-5')oligo(A) synthetase mRNA was identified. In SV80 cells, this E cDNA recognizes three RNAs of 1.65, 1.85, and 3.6 kilobases, which are present only after interferon treatment of the cells. In Namalva cells, mainly one RNA of 1.8 kilobases is seen.
通过在卵母细胞中进行翻译检测,从人细胞中纯化出编码干扰素诱导的(2'-5')寡腺苷酸合成酶的17S RNA组分。通过克隆到大肠杆菌质粒pBR322中制备cDNA文库,并通过在卵母细胞中的阳性杂交-翻译进行筛选。鉴定出一个与(2'-5')寡腺苷酸合成酶mRNA相对应的cDNA克隆。在SV80细胞中,该E cDNA识别1.65、1.85和3.6千碱基的三种RNA,这些RNA仅在细胞经干扰素处理后才出现。在Namalva细胞中,主要可见一种1.8千碱基的RNA。
