Cell Function Design Research Group
Cell Function Design Research Group Overview
The Cell Function Design Research Group aims to engineer “fit-for-purpose cells” for the emerging cell-based bioindustry by redesigning the growth capacity, productivity, and functional stability of microbial and animal cells at the molecular level. By integrating molecular engineering technologies—including gene discovery, genetic manipulation, and expression control—with advanced approaches for optimizing culture conditions and regulating cellular functionality and storage stability, we are building a comprehensive research platform that enables seamless cell design, evaluation, and optimization

Research Project
Project 1:Development of genetic resources using metagenomics
Researcher: SUENAGA Hikaru
Using metagenomic approaches, we have been discovering and collecting genetic resources from microbial communities in environments beyond the scope of conventional culture. By utilizing these genetic sequences, we are applying our findings to synthetic biology and precision fermentation, including the production of novel enzymes and the development of unprecedented gene expression control systems.

Project 2:Control of hydration dynamics by sub-THz waves and elucidation of biomolecular functions
Researcher: IMASHIMIZU Masahiko
Biomolecular functions arise from the selective stabilization of specific structural states out of thermal fluctuations. In this project, we focus on hydration water as a key factor underlying this selectivity. By combining selective perturbation using sub-THz waves with dielectric spectroscopy, along with biochemical approaches and multiple spectroscopic techniques, we investigate the relationship between hydration dynamics and biomolecular functions, and work toward its control.

Project 3:Heterologous protein production in yeasts
Researcher: YOKO-O Takehiko
The methanol-utilizing yeast Ogataea minuta is an excellent host for heterologous protein production. Our research focuses on the development of plasmids and libraries, as well as the generation of high-yield protein-producing strains in this species. Additionally, we study the biosynthetic mechanisms of glycosylphosphatidylinositol (GPI) anchors and the localization mechanisms of glycosyltransferases.

Project 4:Development of an RNA vector for efficient gene delivery and biological applications
Researcher: SANO Masayuki
We have been developing the efficient gene delivery system that leads to high transduction efficiency, long-term expression of coding- and non-coding genes, and control of transgene expression using the persistent RNA vector. The vector system can be used to facilitate cell visualization, regulation of endogenous gene expression, and cell reprogramming and differentiation.

Project 5:Development of High-Efficiency Gene Function Screening for Industrial Cell Line Engineering
Researcher: KATO Shoichi
We have been developing pooled screening technologies that evaluate numerous genetic perturbations in parallel, identifying phenotype-controlling genes and their combinatorial effects. The large-scale perturbation–phenotype data obtained will serve as a training and benchmarking resource for machine learning and foundation models to predict and design perturbation outcomes. Using these screening and AI technologies, we aim to rationally engineer industrial cell lines with enhanced stress tolerance and proliferative capacity.

Project 6:The Cell factory platform: Integrated discovery and host engineering
Researcher: SRISAWAT Pisanee
We focus on developing advanced technologies for the biosynthesis of bioactive compounds, thereby expanding the possibilities for biological assembly of complex molecules. A key aspect of our work is the precise engineering of microbial hosts, transforming them into high-efficiency cellular factories for the large-scale production of industrially relevant compounds. This capability is driven by our systematic exploration of underutilized genetic resources from natural environments, enabling access to a broad library of biological blueprints for the discovery and scalable production of next-generation sustainable solutions.
