The AML1 gene (also known as CBFA2 and RUNX1) is required for differentiation of hematopoietic cells and can act as a gene activator or repressor dependent on the association with either the corepressor Groucho or the HAT complex CBP/p300.

- ETO/RUNX1 fusion gene in acute myeloid leukemia
- The relatively common t(8;21) translocation fuses the DNA-binding domain of AML1 to ETO (eight-twenty-one), which in turn associates with gene repressors such as HDACs and Sin3. The AML1-ETO fusion suppresses AML1 target genes, leading to a block in myeloid differentiation and cellular transformation.
