Research Abstract

Structural studies of the proteins that are associated with human accelerated-aging diseases and the proteins that function in the cell signaling pathway, have been performed. Three-dimensional structures of the “RQC domain of Werner syndrome WRN helicase in complex with double-stranded DNA”, “HRDC domain of Bloom syndrome BLM helicase”, and the “heterotrimeric G protein in complex with its specific inhibitor YM-254890” have been determined. These new structures offered insights into the field of biology and medicine.
