Research Abstract

In eukaryotic cells, DNA replication and repair is intimately connected to chromatin structure. To understand the role of chromatin rerated factors in DNA replication and repair, we generated systematically a number of chicken DT40 mutant cell lines, respectively, lacking each of appropriate genes, CAF-1, which is consisted of p150, p60 and p48 subunit, and ASF1. By analyses of these mutant cells, we have revealed the function of CAF-1 and ASF1-dependent nucleosome assembly in DNA replication, and the relation to DNA damage repair
