Abstract
The AML1 and CBFβ subunits of core binding factor (CBF) are involved in several chromosomal abnormalities frequently associated with acute leukemias. As a result, the CBFβ-SMMHC, AML1-ETO and AML1-MDS1/EVI1 fusion proteins are expressed in subsets of acute myeloid leukemia, and TEL-AML1 is expressed in B-lineage acute lymphocytic leukemia. These CBF oncoproteins likely contribute to leukemogenesis in part by inhibiting endogenous CBF. As a result they are expected to inhibit differentiation and perhaps apoptosis. In addition, the domains unique to each fusion protein may also contribute to leukemogenesis via unique mechanisms.
