◆Specialties
Applied biofunctional and bioprocess engineering
◆Research Keywords
Signal transduction, Liposome, Phase-separation, Dynamics, Antibody Engineering, Genetic Engineering
◆Research Interests
Thermostable proteins
We are interested in thermostable proteins synthesized by hyperthermophilic archaeon. Structure-function relationsips, improvement of enzyme functions by protein engineering, application of thermostable proteins in the fields of medical science, food industries and environment remediation are involved.
Stress response
Intracellular signal transduction by external physical stresses (light, heavy metal, electric magnetic field etc.) will be studied. We are interested in signals related to apoptotic responses.
Protein folding process
Folding process especially amyloid formation will be intensively studied. Neural cell death caused by amyloids is also involved.
Dynamic movement of model membrane and its interaction with proteins
