Characterizing The Interaction Between Human Adenovirus E1a And The Transcriptional Repressor Bs69, Ali Zhang
Electronic Thesis and Dissertation Repository
Protein products of the Early Region 1A (E1A) gene in human adenovirus 5 (HAdV-5) are the first viral proteins expressed upon adenovirus infection. E1A disrupts many cellular physiological events by binding to and regulating an impressive number of host factors. Of particular interest is BS69, a repressor of E1A transactivation. Due to the strong interaction observed between E1A and BS69, I hypothesize that these two proteins function together to disrupt gene expression within an infected cell.
Using in silico modelling and a series of yeast two-hybrid assays, I determined that residues 112-119 of HAdV-5 E1A is the minimal interacting region …
