| Outline of Final Research Achievements |
RUNX1 gene is frequently point mutated or chromosomal translocated in acute leukemia and myelodisplasia. RUNX1 is essential for definitive hematopoiesis in fatal liver and plays a role in hematopoietic development in adult. RUNX1 acts as a transcription factor and regulates gene expression related to hematopoiesis, however regulation of RUNX1 itself has not been elucidated fully. Thus, we identified CRP1, a novel binding factor of RUNX1 and found that it repressed transcriptional regulation by RUNX1. In this research project, we analyzed the mechanism in which CRP1 affected to RUNX1 function and the effect of CRP1 on hematopoiesis regulated by RUNX1 in gene-modified mice. In addition we performed an establishment of a screening system to search compounds which can block the interaction between RUNX1 and CRP1.

| Academic Significance and Societal Importance of the Research Achievements |
RUNX1は白血病発症や造血分化異常と関連する因子であるが、RUNX1の機能を調節する効果的な手法は今まで報告されていなかった。本研究では、新たなRUNX1結合因子を発見し、そしてその因子がRUNX1機能に及ぼす影響を解析した。この因子とRUNX1との相互作用を標的とすることによって、RUNX1の機能不全を回復することができ、将来的には白血病や造血異常の改善に結び付くことが示唆された。したがって、本研究成果は十分な学術的意義および社会的意義を有していると考えられた。
