title: Alteration of ribosomal protein maps in herpes simplex virus type 1 infection.
abstract: At present, the effect of herpes simplex virus infection on the entire proteomes of infected cells is very poorly documented. Following several studies performed over the past few years, the modifications of a sub-cellular fraction induced by herpes simplex virus type 1 can be documented. These studies were performed in order to characterize the virally-induced modifications of a major component of the translational apparatus, the ribosomes. The very basic nature of most of the ribosomal proteins renders them very difficult to separate using isoelectric focusing (IEF). Therefore these studies were achieved using several different but related two-dimensional electrophoretic systems which allowed several two-dimensional ribosomal protein maps to be built. Comparison of the ribosomal protein maps built from non-infected cells with those built from infected cells demonstrated that infection by herpes simplex virus type 1 (HSV-1) induces important modifications of ribosomes: (i) non-reversible phosphorylation of ribosomal protein S6; (ii) unusual phosphorylation of several proteins of the small and the large subunits; and (iii) association of viral and cellular proteins to the ribosomal fraction. An overview of these published studies is presented in this review.
