EBNA-3A supports maintenance of Rb hyperphosphorylation and stabilization in Wp-R latency.

<p>Immunoblots of transfected Sal cells harvested at (A) 4 days or (B) 8 days post-transfection were probed with a pan Rb antibody (Rb), a phospho-specific (pRb) antibody that recognizes the phosphorylated residues Ser807/811, and antibodies to detect p53 and Lamin B (loading control). Light and dark refer to film exposure time.
