The capsid protein encoded by U(L)17 of herpes simplex virus 1 interacts with tegument protein VP13/14.

ABSTRACT: The U(L)17 protein (pU(L)17) of herpes simplex virus 1 (HSV-1) likely associates with the surfaces of DNA-containing capsids in a heterodimer with pU(L)25. pU(L)17 is also associated with viral light particles that lack capsid proteins, suggesting its presence in the tegument of the HSV-1 virion. To help determine how pU(L)17 becomes incorporated into virions and its functions therein, we identified pU(L)17-interacting proteins by immunoprecipitation with pU(L)17-specific IgY at 16 h postinfection, followed by mass spectrometry. Coimmunoprecipitated proteins included cellular histone proteins H2A, H3, and H4; the intermediate filament protein vimentin; the major HSV-1 capsid protein VP5; and the HSV tegument proteins VP11/12 (pU(L)46) and VP13/14 (pU(L)47).
