Schematic representation of MOZ, TIF2, and MOZ-TIF2 fusion proteins. Domains are indicated as follows: LAP, leukemia-associated protein²⁰; HAT, histone acetyltransferase; M-rich, methionine-rich; CID and RID, putative CBP and nuclear receptor interacting domains based on homology with SRC-1.29,30 The MOZ-TIF2 fusion retains the LAP finger and HAT homology domains of MOZ, along with the CID and HAT domains of TIF2.
