Phosphorylation of neurotropic alphaherpesvirus envelope glycoproteins: herpes simplex virus type 2 gE2 and pseudorabies virus gI.

I have examined the state of phosphorylation of the envelope glycoproteins of two neurotropic herpesviruses, HSV-2 and PRV. HSV-2 gE2 and PRV gI, which are the homologues to HSV-1 gE, were found to be phosphorylated and phosphoaminoacid analysis revealed that both contained phosphoserine. These findings are consistent with a conserved phosphorylation of the glycoprotein homologues to HSV gE among the neurotropic alphaherpesviruses.
