| Research Abstract |
Transcription factor, AML1/Runx1, plays a pivotal role in hematopoietic development, and its dysfunction is closely related to leukemogenesis. In this study, the influence of leukemia-associated genomic alterations and post-translational modifications of this molecule were evaluated by use of biochemical analysis and experiments using mouse embryonic stem cells. In contrast to most cases of the leukemia-associated mutations that resulted in functional disruption, some mutants for modification residues of this molecule retained its biological activity. Mutant mouse lines for those mutations were currently being generated, and will be analyzed. A search for interacting molecules of AML1 was also performed as a supporting approach.
