The herpes simplex virus protein VP22 is a major phosphoprotein of
infected cells. In this study, we identify two serine phosphorylation sites within VP22 and show that the N-terminal site is a substrate for
casein kinase II, while the extreme C-terminal site is a substrate for
another, as yet unidentified, cellular kinase. Furthermore, we show
that a mutant of VP22 which has both sites altered is unable to
incorporate phosphate in vivo, confirming that there are no other
phosphorylation sites within VP22.
