| Research Abstract |
To reveal a molecular mechanism regulating the intracellular transport of copper ions, I have noted specific interactions between a copper chaperone, CCS, and a copper-requiring enzyme, SOD1. Inside cells, a copper-bound form of CCS specifically recognizes apo SOD1 and then delivers a copper ion to SOD1. CCS consists of three domains, among which a central domain(CCS-dII) plays a role in recognizing SOD1. In this study, I have performed in vitro biochemical tests using recombinant CCS-dII and SOD1 proteins and found the requirements for these two proteins to associate with each other.
