The MOZ-TIF2 fusion is associated with acute myeloid leukemia (AML) with inv(8)(p11q13). MOZ is a MYST family histone acetyltransferase (HAT), whereas TIF2 is a nuclear receptor coactivator that associates with CREB binding protein (CBP). Here we demonstrate that MOZ-TIF2 has transforming properties in vitro and causes AML in a murine bone marrow transplant assay. The C2HC nucleosome recognition motif of MOZ is essential for transformation, whereas MOZ HAT activity is dispensable. However, MOZ-TIF2 interaction with CBP through the TIF2 CBP interaction domain (CID) is essential for transformation. These results indicate that nucleosomal targeting by MOZ and recruitment of CBP by TIF2 are critical requirements for MOZ-TIF2 transformation and indicate that MOZ gain of function contributes to leukemogenesis.
