Model of ELL protein-protein interactions with EAF1 and EAF2.
(A) EAF1 and EAF2 bind to the amino-terminus of the wild-type ELL protein, but only EAF1 binds to the carboxy-terminus of ELL. (B) The MLL-ELL fusion protein disrupts the amino-terminal protein-protein interaction domain of ELL but retains the carboxy-terminal EAF1 interaction domain.
