Adenovirus Protein ORF3 (image) Salk Institute Share Print E-Mail Caption The tiny adenovirus protein known as ORF3 (shown in green) clears the way for adenovirus replication by creating "zip files" of genes that help the cell defend itself against the virus. O'Shea hopes to exploit this finding to create adenoviruses that selectively destroy cancer cells.
