Research Abstract

In this proposal, we focused UHRF1/2 proteins, which are key molecules of epigenetics regulation. To obtain the fundamental role of epigenetics, we performed the structural and biochemical study of UHRF1 interacting proteins and UHRF2. We revealed the function of UHRF1 interacting proteins and the mechanism of complex formation, and also showed the DNA binding property of UHRF2.
