Membrane deformation and scission by the HSV-1 nuclear egress complex. [PDF]
The nuclear egress complex (NEC) of herpesviruses such as HSV-1 is essential for the exit of nascent capsids from the cell nucleus. The NEC drives nuclear envelope vesiculation in cells, but the precise budding mechanism and the potential involvement of cellular proteins are unclear.

The Great (Nuclear) Escape: New Insights into the Role of the Nuclear Egress Complex of Herpesviruses. [PDF]
ABSTRACT Herpesviruses are unusual among enveloped viruses because they bud twice yet acquire a single envelope. They are also the only known viruses that bud into the nuclear envelope. We discovered that the herpesvirus nuclear egress complex could bud membranes without the help of other proteins by forming a coat-like hexagonal scaffold ...

Abstract Herpesvirus capsids must exit the nucleus to undergo additional maturation steps in the cytoplasm, such as secondary envelopment. This process is orchestrated by the nuclear egress complex (NEC), a conserved heterodimer that deforms the inner nuclear membrane and facilitates capsid egress.

Structural Basis for Capsid Recruitment and Coat Formation during HSV-1 Nuclear Egress
During herpesvirus infection, nascent viral capsids egress the nucleus into the cytoplasm by an unusual mechanism whereby capsids bud at the inner nuclear membrane.

Herpesviral nuclear egress is a fine-tuned regulatory process that defines the nucleocytoplasmic release of viral capsids. Nuclear capsids are unable to traverse via nuclear pores due to the fact of their large size; therefore, herpesviruses evolved to ...

Nuclear envelope budding and its cellular functions
The nuclear pore complex (NPC) has long been assumed to be the sole route across the nuclear envelope, and under normal homeostatic conditions it is indeed the main mechanism of nucleo-cytoplasmic transport.

The Herpes Simplex Virus Protein pUL31 Escorts Nucleocapsids to Sites of Nuclear Egress, a Process Coordinated by Its N-Terminal Domain. [PDF]
Progeny capsids of herpesviruses leave the nucleus by budding through the nuclear envelope. Two viral proteins, the membrane protein pUL34 and the nucleo-phosphoprotein pUL31 form the nuclear egress complex that is required for capsid egress out of the ...
