| Research Abstract |
During the cell proliferation, chromosomes, integral of our DNA information, are needed to be replicated and segregated to each divided daughter cell, correctly. A functional DNA/protein complex named centromere is responsible for chromosome segregation. However, the mechanisms, how centromere structure is organized, is yet unknown. Then, we created the artificial centromere DNA sequence containing a specific protein binding site, and tethered several kinds of chromatin related protein candidates through this binding site. As a result, we found that a kind of protein modification enzyme, histone acetyltransferase, can induce de novo centroemre formation on the centromere DNA sequence.
