EVI1 oncoprotein interacts with a large and complex network of proteins and integrates signals through protein phosphorylation.

ABSTRACT: Ecotropic viral integration site-1 (EVI1) is an oncogenic zinc finger transcription factor whose expression is frequently up-regulated in myeloid leukemia and epithelial cancers. To better understand the mechanisms underlying EVI1-associated disease, we sought to define the EVI1 interactome in cancer cells. By using stable isotope labeling by amino acids in cell culture (SILAC)-based quantitative proteomics, we could confidently assign 78 proteins as EVI1-interacting partners for FLAG-tagged EVI1. Subsequently, we showed that 22 of 27 tested interacting proteins could coimmunoprecipitate with endogenous EVI1 protein, which represented an 81.5% validation rate. Additionally, by comparing the stable isotope labeling by amino acids in cell culture (SILAC) data with high-throughput yeast two h
