Mutations that affect phosphorylation of the adenovirus DNA-binding protein alter its ability to enhance its own synthesis.


The multifunctional adenovirus single-strand DNA-binding protein (DBP) is highly phosphorylated. Its phosphorylation sites are located in the amino-terminal domain of the protein, and its DNA- and RNA-binding activity resides in the carboxy-terminal half of the polypeptide. We have substituted cysteine or alanine for up to 10 of these potential… (More)
