| Research Abstract |
This study has aimed to clarify the molecular function of two RNAi factors DRH-3 (Dicer Related Helicase-3) and E1 (a novel protein with two Tudor domains) that I originally found to be indispensable for germ-line formation in C. elegans. In this study, I generated the DNA constructs for expression of 10 mutated proteins and successfully prepared His- and GST-tagged-native and some of mutated versions of DRH-3 and E1 proteins using the E. coli protein expression system, and showed the physical interaction between DRH-3 and E1 by pull-down method with differently tagged-native proteins. In addition, genetic and cytological observations on both genes have suggested that DRH-3 and E1 proteins act in the same pathway of RNAi in nucleus.
