Protein kinase and ATP-binding activity associated with the 72-kdalton single-stranded DNA-binding protein from early region 2A of human adenovirus type 5

We have developed monoclonal antibodies which react specifically with the human adenovirus type 5 early region 2A 72-kdalton phosphoprotein (72 kDa) and its 48-kdalton proteolytic cleavage product (48 kDa) and have used these antibodies to study a number of properties of these viral polyPeptides. Fluorescent antibody staining indicated that the 72 kDa was found almost entirely in the nucleus, generally in discreet patches. Preparations of the …
