Outline of Project Research Subjects
and Participants
Publications

1. Goals

(1) To isolate useful genes such as those related to the biosynthesis of functional substances by utilizing comprehensive protein analysis, identify their functions.

(2) To elucidate the mechanism of protein structure formation and to establish a technology to control the structure

(3) To clarify the correlation between protein structure and its function and to establish a method to estimate the function

(4) To clarify the functions of unknown genes based on their protein structure.



2. Research plans

1) Comprehensive analysis of protein structure and its function, isolation of useful genes, and identification of their functions

To isolate and define the time-dependent and tissue-specific accumulation of proteins during development in rice
To analyze the partial amino acid sequences of such proteins or post-translational modifications and to compare the results with the information obtained from the base sequence of cDNA
To isolate the genes of functional proteins and clarify their functions by introducing them into plants or other methods

2) Elucidation of the correlation between protein structure and function

To explain the mechanisms of formation of steric structures, such as useful substance-producing enzymes and functional proteins within living organisms, and the correlation between steric structure and function
To establish a technology to control steric structures that will contribute to the production of proteins with new functions.

3) Development of method to estimate steric structure of proteins and their functions
To create a database of information on the conditions for protein expression and post-translational modifications, predict the functions using such database, and upgrade methods for estimating functional domains in the amino acid sequences and predicting the steric structures and functions

4) Identification of the functions of unknown genes based on the steric structure of proteins and correlation between proteins
To conduct the mass expression of gene products using a full-length rice cDNA library and identify their functions based on the analysis of the steric structure of the obtained proteins.
To identify the signal transduction network based on the analysis of interaction among proteins.
