对加州核多角体病毒DNA聚合酶基因下游1·4 kb区域进行了测序。鉴定出两个长度分别为927和474碱基的开放阅读框(orf)。通过927碱基ORF模板的杂交选择RNA和体外合成RNA的体外翻译,确定了927碱基ORF编码34.8 k蛋白。预测的34·8K多肽(p34·8)的氨基酸序列显示了一个疏水的N端,两个潜在的N糖基化位点,以及酪蛋白激酶I和蛋白激酶c的潜在磷酸化位点。p34·8基因具有强烈的密码子使用偏好,这与多面蛋白基因有显著不同。927碱基ORF转录本的两个5 '端分别从ATG密码子上游11个碱基和87个碱基的ATAAG序列和GTAAG序列启动。较长RNA的前导序列中存在较短的上游阅读框。转录本有多个3 '端;最近端与927碱基ORF的翻译终止密码子重叠的多聚腺苷化信号相关。后者的转录本在感染周期早期未被观察到,但在感染后6小时出现,并在感染后12至24小时达到最高表达。这些转录本的晚期性质被证实了它们对阿菲霉素和环己亚胺的敏感性,分别是DNA复制抑制剂和蛋白质合成抑制剂。构建携带p34·8基因缺失并与β-半乳糖苷酶基因融合的病毒突变体的尝试表明,前者基因对病毒复制至关重要。
A 1·4 kb region downstream of the DNA polymerase gene ofAutographa californicanuclear polyhedrosis virus was sequenced. Two open reading frames (ORFs) were identified of 927 and 474 bases in length. The 927 base ORF encodes a 34·8K protein as determined byin vitrotranslation of both hybrid-selected RNA and RNA synthesizedin vitrofrom a 927 base ORF template. The predicted amino acid sequence of the 34·8K polypeptide (p34·8) reveals a hydrophobic N terminus, two potentialN-glycosylation sites, and potential sites for phosphorylation by casein kinase I and protein kinase C. The p34·8 gene has a strong codon usage bias which is strikingly different from that of the polyhedrin gene. The two 5′ ends of the 927 base ORF transcripts initiate from an ATAAG sequence and a GTAAG sequence 11 and 87 bases upstream of the ATG codon respectively. A short upstream reading frame is present in the leader sequence of the longer RNA. The transcripts have multiple 3′ ends; the most proximal endpoint correlates with a polyadenylation signal overlapping the translational termination codon of the 927 base ORF. Transcripts of the latter were not observed early in the infection cycle but appeared 6 h after infection and were maximally expressed at 12 to 24 h post-infection. The late nature of these transcripts was confirmed by their sensitivity to aphidicolin and cycloheximide, inhibitors of DNA replication and protein synthesis respectively. Attempts to construct viral mutants carrying a deletion of the p34·8 gene and fusion with the β-galactosidase gene suggest that the former gene is essential for viral replication.
