Oncoproteins of the MYC family are major drivers of human tumorigenesis. Since a large body of evidence indicates that MYC proteins are transcription factors, studying their function has focused on the biology of the downstream target genes. Detailed studies of MYC-dependent changes in RNA levels have provided contrasting models of the oncogenic activity of MYC through either enhancing or repressing the expression of specific target genes, or as a global amplifier of transcription. In this review, we first overview the biochemistry of MYC proteins and summarize what is known (and unclear) about MYC target genes. We then discuss recent progress in defining the MYC and MYCN interactomes and how this information affects central concepts of MYC biology, focusing on mechanisms by which MYC proteins modulate transcription. MYC proteins promote transcription termination upon stalling of RNA Polymerase II and we propose that this mechanism enhances the stress resilience of basal transcription. Furthermore, MYC proteins co-ordinate transcription elongation with DNA replication and cell cycle progression. Finally, we argue that the mechanism by which MYC proteins regulate the transcription machinery is likely to promote tumorigenesis independently of global or relative changes in the expression of their target genes.
