Adenovirus E1A TRRAP-targeting domain-mediated enhancement of MYC association with the NuA4 complex activates a panel of MYC target genes enriched for gene expression and ribosome biogenesis
چکیده انگلیسی


- E1A N-terminal-MYC chimeric protein associates with the NuA4 complex efficiently.
- A panel of MYC-target genes is preferentially activated by E1A N-terminal-MYC fusion.
- This panel of genes may be activated by MYC association with NuA4 complex.
- This panel of genes may be involved in E1A and MYC-mediated transformation.

Cellular transformation by adenovirus E1A requires targeting TRRAP, a scaffold protein which helps assemble histone acetyltransferase complexes, including the NuA4 complex. We recently reported that E1A and E1A 1-80 (N-terminal 80 aa) promote association of the proto-oncogene product MYC with the NuA4 complex. The E1A N-terminal TRRAP-targeting (ET) domain is required for E1A 1-80 to interact with the NuA4 complex. We demonstrate that an ET-MYC fusion associates with the NuA4 complex more efficiently than does MYC alone. Because MYC regulates genes for multiple cellular pathways, we performed global RNA-sequence analysis of cells expressing MYC or ET-MYC, and identified a panel of genes (262) preferentially activated by ET-MYC and significantly enriched in genes involved in gene expression and ribosome biogenesis, suggesting that E1A enhances MYC association with the NuA4 complex to activate a set of MYC target genes likely involved in cellular proliferation and cellular transformation by E1A and by MYC.
