チームタイトル

ヌクレオソーム図​We research to unravel the mechanisms underlying the movement and functional expression of biomacromolecules such as proteins and nucleic acid complexes. This is achieved through a combination of computational scientific approaches, such as molecular modeling and molecular simulation, and experimental scientific approaches, including single-molecule measurements using optical tweezers and genetic engineering. Specifically, we investigate the binding and dissociation of small molecules with proteins, the relationship between changes in DNA packaging and gene expression, and the creation of novel functional proteins. 

We are currently recruiting researchers on an ongoing basis. Experience in our team offers a valuable opportunity for career growth as a next-generation researcher. Why not leverage your passion and skills to pioneer the future with us?
