| Outline of Final Research Achievements |
Peptide microarray that can profile an intracellular kinome has been established. At first we successfully developed some new substrate peptides for various protein kinases which are important to evaluate effects of anti-cancer drugd. Then, by using these substrates, we prepared an peptide amicroarray and succeeded to get correct kinome profile against stimulation of drugs in living cells. Finally, kinomes of some different anti-cancer drugs, which have different specificity to EGFR and HER2, could be evaluated by the microarray.
For the analysis of tyrosine kinase activities, it was difficult to make specific substrates. Thus, we developed ligand peptides which are specfically bind to target tyrisine kinases. Using the ligand peptiddes, we successfully realize specific and sensitive monitoring of tyrosine kinase profiling.
