Transactivation By Human Adenovirus Early Region 1a-Conserved Region Three, Jailal Ng Ablack

Electronic Thesis and Dissertation Repository

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 …
