A small RNA induced late in simian virus 40 infection can associate with early viral mRNAs.
Analysis of total cytoplasmic and polyadenylylated cytoplasmic RNA from cells lytically infected with simian virus 40 (SV40) has demonstrated the presence of a small RNA, approximately 65 nucleotides long, that is induced late in lytic infection. This small RNA is apparently specific in size and sequence and is not selected on columns of oligo(dT)-cellulose. It is homologous to a region of the early SV40 mRNAs (and to the late DNA strand), starting approximately 250 nucleotides from the 3' end of the early mRNAs (SV40 map position 0.21). The function of this RNA in the viral cycle and its source are unknown at this time; however, its temporal expression, unique sequence, and interesting region of homology within the SV40 genome suggest a possible role in the control of SV40 gene expression.
