UniProtKB description:  Inhibits the integrated stress response (ISR) in the infected cell by preventing the sequestration of eIF2B by phosphorylated EIF2S1/eIF-2alpha (PubMed:32690955). Stress granule formation in response to EIF2S1/eIF-2alpha phosphorylation is thus inhibited, which allows protein synthesis and viral replication (PubMed:32690955). Does not have any proteolytic activity (PubMed:14512530). Required for viral RNA replication and viral RNA encapsidation (PubMed:14512530).
