My research interests relate to the structure and function of proteins, which have been produced by nature through the evolutionary process of life to create new diversified functions with just the 20 amino acids found in nature. To understand the mysteries of proteins including their unique functions and properties, we focus on protein molecular evolution.

最近の研究について

The secrets of a pearl’s luster Pearl luster is one of major quality factors that determine the true beauty of pearl that charms many people. To understand the biomineralization mechanisms of the pearl shell, we focus on the matrix proteins, which regulate the lamellar nano-architechture structure composed of aragonite crystals, and especially on the molecular mechanism regulating the orientation distribution of aragonite crystals.

Experimental Molecular Archeology: Reconstruction of Ancestral Mutants and the Evolutionary History of Proteins To analyze the structure-function relationship of proteins and to design new functional proteins, we have developed a protein engineering system using reconstruction of ancestral mutants based on a phylogenetic tree.

A venomics project of the Protobothrops flavoviridis (Habu) snake Venomous animals produce multiple toxins, which specifically affect the biological systems of prey. We focus on the diverse functions of toxin genes, which demonstrate a unique evolutionary phenomenon: accelerated evolution. To elucidate the unique structural information of toxin-related genes and the mechanism of accelerated evolution, we are conducting whole genome analysis of the venomous snake, Protobothrops flavoviridis. Understanding the molecular mechanisms of accelerated evolution will provide us with a new concept of molecular evolution.

メッセージ

I believe that the skillful fusion of diverse ways of thinking, viewpoints, and research methods leads to unique new research programs. We study proteins from a variety of angles and enjoy the research; from protein structure, function, and evolution, to the application of this information to new materials and functional materials. I would like to encourage you to enjoy these research activities with us.
