猴病毒40(SV40)已被证明是研究哺乳动物DNA复制的一个有用的模型系统(Challberg和Kelly 1989;Hurwitz等人)。1990年;凯利1988年;斯蒂尔曼)。SV40基因组由宿主机器与单一病毒蛋白T抗原一起复制。因此,病毒DNA复制的基本机制对哺乳动物DNA复制很可能是重要的。病毒基因组的合成始于一个明确的来源,与染色体DNA复制一样,以双向和半不连续的方式进行。无细胞复制系统(Li和Kelly 1984;Li和Kelly 1985)的发展证明了这一相对简单的系统的实用性,该系统允许识别与哺乳动物DNA复制有关的因素。体外复制被证明具有体内SV40DNA复制的大部分特征(Li和Kelly 1984;Li和Kelly 1985;Li et al.1986年;Stillman等人。1985年;Stillman和Gluzman 1985年;Wobbe等人。1985年)。尤其是病毒蛋白T抗原的启动,发生在DNA复制的起始点,并且是双向进行的。此外,体外形成的复制中间体与体内发现的复制中间体是相同的。
Simian virus 40 (SV40), has proved to be a useful model system for the study of mammalian DNA replication (Challberg and Kelly 1989; Hurwitz et al. 1990; Kelly 1988; Stillman 1989). The SV40 genome is replicated by the host machinery in conjunction with a single viral protein, T antigen. Thus, the basic mechanisms involved in the replication of viral DNA are likely to be important for mammalian DNA replication. Synthesis of the viral genome begins at a well-defined origin and, like chromosomal DNA replication, proceeds in a bidirectional and semidiscontinuous manner. The utility of this relatively simple system is exemplified by the development of a cell-free replication system (Li and Kelly 1984; Li and Kelly 1985) which has allowed the identification of factors implicated in the replication of mammalian DNA. Replication in vitro was demonstrated to possess most of the characteristics of in vivo SV40 DNA replication (Li and Kelly 1984; Li and Kelly 1985; Li et al. 1986; Stillman et al. 1985; Stillman and Gluzman 1985; Wobbe et al. 1985). In particular, initiation depended on the viral protein T antigen, occured at the origin of DNA replication, and proceeded bidirectionally. Furthermore, replication intermediates formed in vitro were identical to those found in vivo.
