원숭이 신장 세포에서 M13 DNA에 의한 SV40 DNA 복제 억제 현상에 대하여
Inhibition of SV40 DNA replication in simian cell by bacteriophage M13 DNA sequences
초록
Bacteriophage M13 DNAs carrying the wild type or base substituted SV40 DNA replication origins were used for replication assay. In vivo and in vitro assay with African green monkey cell line COS-1 showed that the replication of M13-SV40 recombinant DNAs was restricted like a pBR322 SV40 recombinant DNA(Lusky and Botchan, 1981). Furthermore, recombinant phage DNAs isolated from the transfected siminan cells subsequently show a reduced ability to retransform E. coli. But pATSV-W(Kim et al., 1988) was replicated in COS-1 cells normally. We think that a poison sequence may exist on bacteriophage M13 DNA like pBR322.
