Research Interests

The H. Moriyama Lab is interested in the structure and function of proteins that trigger biological processes, in order to better understand and treat metabolic and behavior disorders. Our research involves the interdisciplines of mathematical biology, biophysics, chemical biology, molecular and structural biology plus bioinformatics. Our passion is to reconstruct critical signaling nodes how these drive responses based on the substance oriented science.

Protein Allostery and Modulators
We are interested in the internal protein atomic network. How protein preserves the energy to give allosteric motion upon ligand binding? Can we discover the method to cancel the preserved energy to be used in the protein motions? We are using the time-resolved protein crystallography and the small angle scattering using free electron laser, X-ray, and neutron as probes.

Chemoreceptor Signaling Pathways
We are working to communicate with many chemoreceptor in animals, including insects and monkeys. Which chemical compounds are chemoreceptor targets? How are thy recognized by the chemoreceptor? Can we extract the voice of chemoreceptors? Can we change the tone in the therapeutic purpose?

Temperature Deriven Evolution
We are approaching the problem how enzymes’ optimal temperature and pH defined. Can we address enzymes from organisms found by the antarctic drilling as the most evolved version of that from the hot spring organisms? What are the fine tuning methods nature used to fit the optimal temperature and pH in the process of adaptation? How large is the functional merging do organisms allow?
