The relative levels of expression of the five 3'-coterminal mRNA families encode in the 16.4 to 99 map unit transcription unit of adenovirus type 2 (Ad2) are determined in part by the frequency of utilization of five possible polyadenylation sites. The possibility that polyadenylation frequencies at these sites may be regulated was tested by examining the expression of the fiber (polypeptide IV) gene in cells infected with nondefective (ND) Ad2-simian virus 40 hybrid viruses which express a sixth late mRNA family. Both the relative rate of fiber protein synthesis and the relative abundance of fiber mRNA were normal in cells infected with the hybrid viruses Ad2+ND1, Ad2+ND2, or Ad2+ND4.
在2型腺病毒(Ad2)16.4至99图单位转录单位中编码的五个3' 共末端mRNA家族的相对表达水平,部分由五个可能的聚腺苷酸化位点的使用频率决定。通过检测纤维(多肽IV)基因在感染了表达第六个晚期mRNA家族的无缺陷(ND)Ad2-猴病毒40杂交病毒的细胞中的表达,来测试这些位点处聚腺苷酸化频率可能受到调控的可能性。在感染杂交病毒Ad2+ND1、Ad2+ND2或Ad2+ND4的细胞中,纤维蛋白合成的相对速率和纤维mRNA的相对丰度均正常。
