Many functions are attributed to VP22, including nuclear localization, chromatin binding, microtubule binding, induction ofmicrotubule reorganization, intercellular transport, interaction with cellular proteins, such as template activating VP16, pU factor I （TAF-I） and nonmuscle myosin II A （NMIIA）, and viral proteins including pUS9 and pUL46, glycoprotein E （gE） and gD. Recently, many novel functions perform tegument protein ed by the HSV-1 VP22 protein have been shown, including promotion of protein synthesis at late times in infection, accumulation of a subset of viral mRNAs at early times in infection and possible transcriptional regulation function .展开更多
