Unexpected features and mechanism of heterodimer formation of a herpesvirus nuclear egress complex. [PDF]
AbstractHerpesvirus nucleocapsids escape from the nucleus in a process orchestrated by a highly conserved, viral nuclear egress complex. In human cytomegalovirus, the complex consists of two proteins, UL50 and UL53. We solved structures of versions of UL53 and the complex by X‐ray crystallography.

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.

Host and Viral Factors Involved in Nuclear Egress of Herpes Simplex Virus 1
Herpes simplex virus 1 (HSV-1) replicates its genome and packages it into capsids within the nucleus. HSV-1 has evolved a complex mechanism of nuclear egress whereby nascent capsids bud on the inner nuclear membrane to form perinuclear virions that ...

The universal suppressor mutation restores membrane budding defects in the HSV-1 nuclear egress complex by stabilizing the oligomeric lattice. [PDF]
Nuclear egress is an essential process in herpesvirus replication whereby nascent capsids translocate from the nucleus to the cytoplasm. This initial step of nuclear egress-budding at the inner nuclear membrane-is coordinated by the nuclear egress ...

Herpesviruses uniquely express two essential nuclear egress-regulating proteins forming a heterodimeric nuclear egress complex (core NEC). These core NECs serve as hexameric lattice-structured platforms for capsid docking and recruit viral and cellular ...

The Herpesvirus Nuclear Egress Complex Component, UL31, Can Be Recruited to Sites of DNA Damage Through Poly-ADP Ribose Binding [PDF]
The herpes simplex virus (HSV) UL31 gene encodes a conserved member of the herpesvirus nuclear egress complex that not only functions in the egress of DNA containing capsids from the nucleus, but is also required for optimal replication of viral DNA and ...

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.
