Outline of Final Research Achievements

Three approaches were utilized to examine the feasibility of biotechnological application of CaMKII memory function: biochemical experiments, cellar and molecular biological experiments, and computer simulation. I developed the insect cell expression system of CaMKII-FRET, and also developed the optical observation/simulation system of target molecules in HeLa cells. The CaMKII memory system is also applicable. Also, I computationally simulated the reaction-diffusion system of the memory-related molecules in morphologically realistic dendrites and spines, to examine localization of those molecules.
