Primary envelopment of Kaposi’s sarcoma-associated herpesvirus at the nucleoplasmic reticulum [PDF]
Herpesvirus egress begins with primary envelopment of newly assembled capsids at the inner nuclear membrane (INM). Primary envelopment has been observed at the peripheral INM as well as nuclear infoldings. Nuclear infoldings from invaginations of the INM

Autographa californica multiple nucleopolyhedrovirus Ac51 interacts with Ac66 and facilitates its nuclear localization to promote the nuclear egress of nucleocapsids [PDF]
Autographa californica multiple nucleopolyhedrovirus is a large DNA virus that replicates within host nuclei. The mechanism underlying the nuclear egress of viral nucleocapsids is not fully understood.

Herpesviruses replicate their genomes and assemble their capsids in the host cell nucleus. To progress towards morphogenesis in the cytoplasm, herpesviruses evolved the strategy of nuclear egress as a highly regulated process of nucleo-cytoplasmic capsid

Mutational Functional Analysis of the Pseudorabies Virus Nuclear Egress Complex-Nucleocapsid Interaction. [PDF]
Herpesviruses encode an exceptional vesicle formation and scission machinery, which operates at the inner nuclear membrane, translocating the viral nucleocapsid from the nucleus into the perinuclear space. The conserved herpesviral nuclear egress complex (NEC) orchestrates this process.

NECing goes: flexibility of the herpesvirus nuclear egress complex
AbstractThe nuclear egress complex (NEC) allows herpesvirus capsids to escape from the nucleus without breaking the nuclear envelope barrier. It assembles into a lattice on the inner nuclear membrane enveloping newly assembled nucleocapsids, which bud into the perinuclear space.

Human cytomegalovirus UL97 phosphorylates the viral nuclear egress complex. [PDF]
ABSTRACT Herpesvirus nucleocapsids exit the host cell nucleus in an unusual process known as nuclear egress. The human cytomegalovirus (HCMV) UL97 protein kinase is required for efficient nuclear egress, which can be explained by its phosphorylation of the nuclear lamina component lamin A/C, which disrupts the nuclear lamina.

Functional Identification and Characterization of the Nuclear Egress Complex of a Gammaherpesvirus. [PDF]
Increasing amounts of knowledge indicate that the nuclear egress complex (NEC) is critical for the nuclear egress of herpesvirus capsids, which can be viewed as a vesicle-mediated transport pathway through the nuclear membrane. In this study, we identified open reading frame 67 (ORF67) and ORF69 as components of the NEC in murine gammaherpesvirus 68 ...

Proteomic analysis of the multimeric nuclear egress complex of human cytomegalovirus. [PDF]
Herpesviral capsids are assembled in the host cell nucleus before being translocated into the cytoplasm for further maturation. The crossing of the nuclear envelope represents a major event that requires the formation of the nuclear egress complex (NEC).

The crystal structure of the varicella-zoster Orf24-Orf27 nuclear egress complex spotlights multiple determinants of herpesvirus subfamily specificity. [PDF]
ABSTRACTVaricella zoster virus (VZV) is a human pathogen from the α-subfamily of herpesviruses. Here, the crystal structure of the VZV Orf24-Orf27 complex is described, representing the essential viral core nuclear egress complex (NEC) that orchestrates the egress of the preassembled capsids from the nucleus.
