1 型人乳头瘤病毒 (HPV-1) 会引起足底疣。根据先前绘制的 HPV-1 与其他乳头瘤病毒的 mRNA 和序列同源性,我们设计了寡核苷酸引物并采用聚合酶链式反应从足底疣中回收 HPV-1 cDNA。对七种剪接 RNA 进行了表征,其中包括三种以前未检测到的RNA,并推导了每种剪接RNA的编码潜力。最丰富的病毒 mRNA 编码 E1i--E4 蛋白。预计一个新物种能够编码全长 E2 蛋白,而另一个新物种理论上可以编码 E2-C 或 E1-M 蛋白,这三种蛋白调节 mRNA 转录和 DNA 复制。一种源自上游调控区的新型 HPV 启动子的 RNA 物种具有编码小衣壳蛋白 L2 的潜力。新识别的 E5a 开放阅读框 (ORF) 包含在所有在 E 区 Poly(A) 位点进行聚腺苷酸化的 mRNA 中,以及推定的 L2 mRNA 中。三个不同的物种,其中两个源自上游调控区启动子,有可能编码 L1 蛋白;第三个物种还包含 L1 ORF 5'端的 E1i-E4 蛋白的整个编码区。 E1i--E4 mRNA 和潜在的双顺反子 L1 mRNA 均源自位于 E7 ORF 中的启动子。我们没有发现任何证据表明选择性剪接的 mRNA 可以解释跖疣中多种、丰富的 E4 蛋白,这表明翻译后修饰是观察到的蛋白质异质性的主要原因。
Human papillomavirus type 1 (HPV-1) causes plantar warts. On the basis of previously mapped mRNAs and sequence homologies of HPV-1 to other papillomaviruses, we designed oligonucleotide primers and employed the polymerase chain reaction to recover HPV-1 cDNAs from plantar warts. Seven spliced RNA species were characterized, including three not previously detected, and the coding potentials of each were deduced. The most abundant viral mRNA encodes an E1i--E4 protein. One new species is predicted to encode the full-length E2 protein, and another can, theoretically, encode the E2-C or E1-M proteins, three products that regulate mRNA transcription and DNA replication. One RNA species originating from a novel HPV promoter in the upstream regulatory region has the potential to encode the minor capsid protein L2. A newly recognized E5a open reading frame (ORF) is contained in all mRNAs that are polyadenylated at the E-region poly(A) site and also in a putative L2 mRNA. Three distinct species, two of which are derived from the upstream regulatory region promoter, have the potential to encode the L1 protein; the third species also contains the entire coding region of the E1i--E4 protein 5' to the L1 ORF. Both the E1i--E4 mRNA and the potentially bicistronic L1 mRNA are derived from a promoter located in the E7 ORF. We uncovered no evidence of alternatively spliced mRNAs that could account for the multiple, abundant E4 proteins in plantar warts, suggesting that posttranslational modification is mainly responsible for the observed protein heterogeneity.
