Kuwahara K, Yoshida M, Kondo E, Sakata A, Watanabe Y, Abe E, et al
. A novel nuclear phosphoprotein, GANP, is up-regulated in centrocytes of the germinal center and associated with MCM3, a protein essential for DNA replication. Blood. 2000;95:2321-8 pubmed
..These results suggest that the up-regulation of GANP might participate in the development of Ag-driven B cells in GCs through its interaction with MCM3. ..
Tateishi S, Sakuraba Y, Masuyama S, Inoue H, Yamaizumi M. Dysfunction of human Rad18 results in defective postreplication repair and hypersensitivity to multiple mutagens. Proc Natl Acad Sci U S A. 2000;97:7927-32 pubmed
..Stable transformants with hRad18 mutated in this motif become sensitive to UV, methyl methanesulfonate, and mitomycin C, and are defective in the replication of UV-damaged DNA. Thus, hRAD18 is a functional homologue of RAD18. ..
Hiraga S, Ichinose C, Onogi T, Niki H, Yamazoe M. Bidirectional migration of SeqA-bound hemimethylated DNA clusters and pairing of oriC copies in Escherichia coli. Genes Cells. 2000;5:327-41 pubmed
..A single cluster of SeqA-bound hemimethylated DNA segment separates into two clusters and these clusters migrate abruptly in a bipolar fashion during progress of replication and prior to separation of linked sister oriC copies. ..
Onogi T, Ohsumi K, Katayama T, Hiraga S. Replication-dependent recruitment of the beta-subunit of DNA polymerase III from cytosolic spaces to replication forks in Escherichia coli. J Bacteriol. 2002;184:867-70 pubmed
..When chromosome replication is terminated after incubation at nonpermissive temperature in a temperature-sensitive dnaC mutant, the beta-subunit is located in the cytosolic spaces of the cell poles. ..
Watanabe K, Tateishi S, Kawasuji M, Tsurimoto T, Inoue H, Yamaizumi M. Rad18 guides poleta to replication stalling sites through physical interaction and PCNA monoubiquitination. EMBO J. 2004;23:3886-96 pubmed
..These results suggest that Rad18 is crucial for recruitment of poleta to the damaged site through protein-protein interaction and PCNA monoubiquitination. ..
Masuyama S, Tateishi S, Yomogida K, Nishimune Y, Suzuki K, Sakuraba Y, et al
. Regulated expression and dynamic changes in subnuclear localization of mammalian Rad18 under normal and genotoxic conditions. Genes Cells. 2005;10:753-62 pubmed
..No de novo protein synthesis is required for this process. These results suggest that in higher eukaryotes, the maintenance and dynamic translocation of Rad18 protein is important for postreplication repair. ..
Matsuda K, Makise M, Sueyasu Y, Takehara M, Asano T, Mizushima T. Yeast two-hybrid analysis of the origin recognition complex of Saccharomyces cerevisiae: interaction between subunits and identification of binding proteins. FEMS Yeast Res. 2007;7:1263-9 pubmed
..We discuss roles of these interactions in functions of ORC. ..
Ono Y, Sakai A, Takechi K, Takio S, Takusagawa M, Takano H. NtPolI-like1 and NtPolI-like2, bacterial DNA polymerase I homologs isolated from BY-2 cultured tobacco cells, encode DNA polymerases engaged in DNA replication in both plastids and mitochondria. Plant Cell Physiol. 2007;48:1679-92 pubmed publisher
..Taken together, our results suggest that NtPolI-like1/2 genes encode DNA polymerases engaged in DNA replication in both plastids and mitochondria...
Tsuji Y, Watanabe K, Araki K, Shinohara M, Yamagata Y, Tsurimoto T, et al
. Recognition of forked and single-stranded DNA structures by human RAD18 complexed with RAD6B protein triggers its recruitment to stalled replication forks. Genes Cells. 2008;13:343-54 pubmed publisher
..These results suggest that RAD18 complexed with RAD6B is recruited to stalled replication forks via interactions with forked DNA or long ssDNA structures, a process that is required for initiating PRR. ..
