In this study, we systemically deciphered the impact of the viral μ2 protein from MRV on transcripts encoding the U5 snRNP proteins EFTUD2, PRPF8, and SNRNP200, in an effort to understand how μ2 triggers a reduction in the level of their corresponding proteins during viral infection [16]. The gene discussed is EFTUD2; the disease is viral infectious disease.
