The complete DNA sequence of the human JC virus, which was found to consist of 5,130 nucleotide pairs, is presented. The amino acid sequence of six proteins could be deduced: the early, nonstructural proteins, large T and small t antigens; the late capsid proteins, VP1, VP2, and VP3; and the agnogene product encoded within the late leader sequence, called the agnoprotein in simian virus 40. The extent of homology between JC virus DNA and the genomes of simian virus 40 (69%) and BK virus (75%) confirmed the close evolutionary relationship of these three polyomaviruses. The sequences showing the greatest divergence in these viral DNAs occurred within the tandem repeats located to the late side of the replication origins.
本文展示了人类JC病毒的完整DNA序列,该序列由5130个核苷酸对组成。可以推导六种蛋白质的氨基酸序列:早期非结构蛋白大T抗原和小t抗原;晚期衣壳蛋白VP1、VP2和VP3;以及在晚期前导序列中编码的agnogene产物,在猴病毒40中称为agnoprotein。JC病毒DNA与猴病毒40基因组(69%)和BK病毒基因组(75%)之间的同源程度证实了这三种多瘤病毒之间密切的进化关系。这些病毒DNA中差异最大的序列出现在复制起点下游的串联重复序列中。
