Outline of Final Research Achievements

GATA1/GATA2 and PU.1 are known to function antagonistically during hematopoietic development. However, these factors are co-expressed in mast cells, and activate the expression of the Ms4a2 gene encoding the β chain of the high-affinity IgE receptor (FcεRI). The present study investigated the roles of GATA2 and PU.1 on Ms4a2 gene transcription. Gene ablation experiments revealed that GATA2 and PU.1 almost equally contributed to the Ms4a2 gene expression. A chromatin immunoprecipitation analysis showed that they shared DNA binding to the +10.4 kb region downstream of the Ms4a2 gene, whereas the proximal -0.06 kb region was exclusively bound by GATA2. Furthermore, we showed that the ablation of the +10.4 kb region by genome editing abolished the Ms4a2 gene expression. Collectively, these results suggest that PU.1 plays central roles in the formation of active chromatin structure, whereas GATA2 directly activates the Ms4a2 promoter.

Academic Significance and Societal Importance of the Research Achievements

GATA転写因子とPU.1がお互いの発現を抑制し拮抗的に作用することは、血球細胞の分化過程で重要な分子基盤として知られてきた。本研究では、Ms4a2遺伝子の発現制御機構をモデルとしてGATA2とPU.1の協調的作用を示し、マスト細胞には従来知られていた両者の拮抗的作用とは異なる転写因子ネットワークが存在することを示した。ヒトMs4a2遺伝子のコード領域のバリアントは気管支喘息等のリスクと関連する。今回明らかにした遺伝子発現制御の仕組みがヒトでも保存されていれば、同遺伝子の非コード領域においても、病的バリアントや構造多型がヒト疾患リスクに関与している可能性がある。
