Electronic Thesis and Dissertation Repository
Human Adenovirus (HAdV) E1A is the first protein expressed during viral infection. The primary function of E1A is to reprogram the cell for viral replication, but it is additionally capable of transforming primary rodent cells in co-operation with other oncogenes such as HAdV E1B. Despite extensive study, little is known about the function and cellular targets of the C-terminal region of E1A. Importantly, this region is required for the transforming ability of E1A with E1B, but can also suppress transformation with Ras. Previous studies showed that interaction with the C-terminal Binding Protein (CtBP) plays a role in both functions described …

One of the critical functions of human adenovirus (hAd) early region 1A (E1A) protein is to activate transcription of the early viral genes. The largest isoform of E1A contains a unique region termed conserved region 3 (CR3), which includes a Cysteine-4 (C4) zinc finger domain. This region activates viral gene expression by interacting with and recruiting cellular transcription machinery to the regulatory regions of early viral genes. Although this process has been studied at length with hAd type 5 E1A, far less is known about how the E1A proteins from other hAd types activate transcription. There are dramatic differences in …
