Open reading frame 11 (ORF11) is a conserved gammaherpesvirus gene that remains undefined. We identified the product of murine gammaherpesvirus 68 (MHV-68) ORF11, p43, as a virion component with a predominantly perinuclear distribution in infected cells. MHV-68 lacking p43 grew normally in vitro but showed reduced lytic replication in vivo and a delay in seeding to the spleen. Subsequent latency amplification was normal. Thus, MHV-68 ORF11 encoded a virion component that was important for in vivo lytic replication but dispensable for the establishment of latency.
开放阅读框11(ORF11)是一种保守的γ疱疹病毒基因,其功能尚不清楚。我们鉴定出鼠γ疱疹病毒68(MHV-68)的ORF11产物p43是一种病毒体成分,在感染细胞中主要分布于核周。缺乏p43的MHV-68在体外生长正常,但在体内的裂解复制减少,且在播种到脾脏时出现延迟。随后的潜伏扩增正常。因此,MHV-68的ORF11编码一种病毒体成分,该成分对体内裂解复制很重要,但对潜伏的建立并非必需。
