title: ETO interacting proteins.
abstract: The 8;21 translocation produces a fusion between the ETO gene and that encoding the myeloid transcription factor AML1. The AML1-ETO fusion substitutes the majority of the ETO protein for the coregulator recruitment domains of AML1. Biochemical analyses of ETO have led to the identification of numerous interacting proteins including many corepressors. Importantly, the proteins interacting with ETO are different from those of wild-type AML1, suggesting that altered coregulator recruitment underlies the oncogenic properties of AML1-ETO. The list of corepressors capable of binding ETO includes histone deacetylases (HDACs) and components of distinct HDAC core complexes. These investigations have provided mechanistic insight into corepressor recruitment by ETO and clues to the leukemogenic activity of AML1-ETO.
