Roles for herpes simplex virus type 1 UL34 and US3 proteins in disrupting the nuclear lamina during herpes simplex virus type 1 egress

Virology. 2006 Apr 10;347(2):261-76. doi: 10.1016/j.virol.2005.11.053. Epub 2006 Jan 19.


Cells infected with wild type HSV-1 showed significant lamin A/C and lamin B rearrangement, while UL34-null virus-infected cells exhibited few changes in lamin localization, indicating that UL34 is necessary for lamin disruption. During HSV infection, US3 limited the development of disruptions in the lamina, since cells infected with a US3-null virus developed large perforations in the lamin layer. US3 regulation of lamin disruption does not correlate with the induction of apoptosis. Expression of either UL34 or US3 proteins alone disrupted lamin A/C and lamin B localization. Expression of UL34 and US3 together had little effect on lamin A/C localization, suggesting a regulatory interaction between the two proteins. The data presented in this paper argue for crucial roles for both UL34 and US3 in regulating the state of the nuclear lamina during viral infection.
