X-ray crystallography for macromolecular complexes

Organismal bodies and biogenic activities are sustained by various macromolecules including proteins, DNA, and RNA. These bio-molecules express their functions or activities by interacting with each other or by forming gigantic molecular complexes. Studying the three-dimensional structures of these bio-molecules allows us to understand their action mechanism. We employ X-ray crystallography for the structural analyses. The obtained three-dimensional structures provide not only insights into detailed molecular mechanisms, but also firm bases for applied researches such as drug development.

Epi-nucleosome’ technologies (Precise reconstitution of epigenetic nucleosomes)

Epigenetic information is ‘added’ onto genetic information, which regulates gene expression of individual cell. This ‘additional’ information is substantialized by chemical modification onto nucleosome that is composed of DNA and histone proteins. The modification of the histone proteins is recorded on the nucleosome, as combinations of the kind of modifications (acetylation, methylation, phosphorylation etc.), and the kind of the subunit and residues modified. These combinatorial information is maintained, recognized and converted in the cell. Although the regulatory mechanisms of epigenetics have been extensively analyzed at the cellular level, biochemical analyses mostly remained at those using modified peptides as pseudo-substrate of chromatin.

Cell-Free Protein Production System

Cell-free protein production system consists of RNA polymerase, transfer RNAs (tRNAs), aminoacyl-tRNA synthetases, translation factors, ribosomes, and DNA for the template of a target protein.

Cell-free system that recapitulates miRNA-mediated mRNA regulation.

Regulation of translation and mRNA degradation is based on a complex interplay of canonical factors, diverse RNA-binding proteins, and non-coding regulatory RNAs (e.g. microRNAs). We have established an in vitro experimental system to recapitulate mechanisms of miRNA-mediated post-transcriptional control by utilizing a cell-free translation technique.

Production and Crystallization of Membrane Proteins

Membrane proteins play indispensable roles in the living cells, such as signal transduction between outside and inside of the cell (receptors), solute transporters, ion channels, and so on, thus many of them have been drug discovery targets.

Structural analysis of bio-macromolecular complexes in electron cryo-microscopy

Structural analysis of bio-macromolecular complexes in electron cryo-microscopy (cryo-EM) is a relatively new method in structural biology.There are two major methods in the cryo-EM, one is called cryo-electron tomography and the other is single particle cryo-EM.

Technique to detect tissue fibrogenesis using the antibodies against TGF-β LAP degradation products

The most fibrogenic cytokine, TGF-β, is produced as a latent complex, in which active TGF-β is wrapped by latency associated protein (LAP), preventing TGF-β from binding its receptor on target cells.

The “KOKORO scale”, a system to assess human mood or mental state.

The “KOKORO scale”, which was developed by Cellular Function Imaging Team is a system in which individuals can input mood information simply with a touch panel or other device. It utilizes four-quadrant matrix*1 with measures of mood including feelings of security and anxiety, feelings of excitement and irritability, and level of motivation (feeling considerable motivation and feeling no motivation) on horizontal and vertical axes.

CAGE : A method for genome-wide identification of transcription start sites

Cap Analysis Gene Expression is a technology focused on the 5' sequence analysis, capturing capped 5' end of RNAs, originally developed by RIKEN in 2003. TSS sequence is quite informative, since you can find corresponding promoter sequence and thereby, you can also predict transcription factor regulation for each transcript.

ZENBU: Interactive visualization and analysis genome browser system

The ZENBU Genome Browser was developed at RIKEN for the FANTOM 5 project. ANTOM5 needed a more powerful genome browser system which could manage CAGE & RNAseq transcriptomics data from 1000s of different cell and tissue samples. ZENBU is a next-generation Sequencing (NGS) focused genome browser for transcriptomics and epigentics data.

Technologies for FANTOM Web Resources

Recent genomics data tends to be large-scale and diverse, for example, tables, texts, DNA/RNA sequences, images, and so forth. As such, well-organized visualization and databases systems are required to access the data. In the FANTOM5 project, we created a series of database systems for this purpose.

ACCIS: Automated Cell Culturing System

Cells possess all of its genetic materials required to function (e.g. DNA and RNA) and these genetic materials can be extracted and profiled to understand the cellular function. Further, because in vitro cells can be maintained with precise step-by-step procedures, we developed an Automated Cell Culturing System (ACCIS) in order to screen for cellular functions by genetic perturbation (e.g. Loss-of-function or gain-of-function).
