We also hypothesize that BPR1P0034 is a general (nonspecific) inhibitor that inhibits viral infection not only in the early stages but also in the late stages (5-12 h p.i.)of infection, in processes such as RNP export from the nucleus, the glycosylation and transport of viral proteins, NA maturation, and viral packaging. The gene discussed is XK; the disease is viral infectious disease.
