Outline of Final Research Achievements |
C/EBPα plays a role in granulopoiesis and is critical for acute myeloid leukemia. C/EBPα functionally and physically interacts with GABP to activate the human myeloid IgA Fc receptor (FCAR) promoter. To understand role of this interaction in myeloid transcription and differentiation, we identified the C/EBPα C-terminus as the GABP-interacting region. Deletion analysis revealed that the C-terminus is essential for granulopoiesis of K562 cells, and can be subdivided for the ability to induce granulocyte markers. In addition, yeast two-hybrid screening using this region as bait identified several interactors, which include a polycomb component, suggesting its involvement in epigenetic regulation.
