FOXR2 Interacts with MYC to Promote Its Transcriptional Activities and Tumorigenesis

By combining the results of a large-scale proteomic analysis of the human transcription factor interaction network with knowledge databases, we identified FOXR2 as one of the top-ranked candidate proto-oncogenes. Here, we show that FOXR2 forms a stable complex with MYC and MAX and subsequently regulates cell proliferation by promoting MYC’s transcriptional activities. We demonstrate that FOXR2 is highly expressed in several breast, lung, and...
