Upon viral infection of a host cell, each virus starts a program to generate many progeny viruses. Although viruses interact with the host cell in numerous ways, one critical step of the virus life cycle is the expression of viral proteins, which are synthesized by the host ribosomes in conjunction with host translation factors. Here we review different mechanisms viruses have evolved to effectively seize host cell ribosomes, the roles of specific ribosomal proteins and their posttranslational modifications on viral RNA translation or the cellular response to infection. We will further highlight ribosomal proteins with extraribosomal function during viral infection and put the knowledge of ribosomal proteins during viral infection into the larger context of ribosome-related diseases, known as ribosomopathies. All viruses require host cell ribosomes for expression of viral proteins, starting a battle between the host cell and the virus for ribosomes. Viruses usurp specific ribosomal proteins to facilitate viral protein biosynthesis. Viruses directly or indirectly induce posttranslational modifications, or utilize extraribosomal functions in other steps of the virus life cycle. In contrast, cells try to control and limit viruses’ ribosome access, either by altering posttranslational modifications of ribosomes, by blocking viral replication, or by blocking other steps of the virus life cycle where ribosomal proteins function outside of the ribosome.
