Molecular cloning and sequence of partial cDNA for interferon-induced (2'-5')oligo(A) synthetase mRNA from human cells.


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.
