ABSTRACT

In light of the scarcity of reports on the interaction between HSV-1 nucleocapsid protein UL25 and its host cell proteins,the purpose of this study is to use yeast two-hybrid screening to search for cellular proteins that can interact with the UL25 protein.C9orf69,a protein of unknown function was identified.The interaction between the two proteins under physiological conditions was also confirmed by biological experiments including co-localization by fluorescence and immunoprecipitation.A preliminary study of the function of C9orf69 showed that it promotes viral proliferation.Further studies showed that C9orf69 did not influence viral multiplication efficiency by transcriptional regulation of viral genes,but indirectly promoted proliferation via interaction with UL25.

ABSTRACT

An interaction between the HSV-1 UL25 capsid protein and cellular microtubule-associated protein was found using a yeast two-hybrid screen and β-D-galactosidase activity assays. Immunofluorescence microscopy of the UL25 protein demonstrated its co-localization with cellular microtubule-associated protein in the plasma membrane. Further investigations with deletion mutants suggest that UL25 is likely to have a function in the nucleus.
