Nuclear Egress Complexes of HCMV and Other Herpesviruses: Solving the Puzzle of Sequence Coevolution, Conserved Structures and Subfamily-Spanning Binding Properties

Viruses, 2020
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 ...

Phenotypical Characterization of the Nuclear Egress of Recombinant Cytomegaloviruses Reveals Defective Replication upon ORF-UL50 Deletion but Not pUL50 Phosphosite Mutation

Viruses, 2021
Nuclear egress is a common herpesviral process regulating nucleocytoplasmic capsid release. For human cytomegalovirus (HCMV), the nuclear egress complex (NEC) is determined by the pUL50-pUL53 core that regulates multicomponent assembly with NEC ...

Conquering the Nuclear Envelope Barriers by EBV Lytic Replication

Viruses, 2021
The nuclear envelope (NE) of eukaryotic cells has a highly structural architecture, comprising double lipid-bilayer membranes, nuclear pore complexes, and an underlying nuclear lamina network.

Vesicular Nucleo-Cytoplasmic Transport—Herpesviruses as Pioneers in Cell Biology

Viruses, 2016
Herpesviruses use a vesicle-mediated transfer of intranuclearly assembled nucleocapsids through the nuclear envelope (NE) for final maturation in the cytoplasm.

Venture from the Interior—Herpesvirus pUL31 Escorts Capsids from Nucleoplasmic Replication Compartments to Sites of Primary Envelopment at the Inner Nuclear Membrane

Cells, 2017
Herpesviral capsid assembly is initiated in the nucleoplasm of the infected cell. Size constraints require that newly formed viral nucleocapsids leave the nucleus by an evolutionarily conserved vescular transport mechanism called nuclear egress.

Herpesvirus Nuclear Egress across the Outer Nuclear Membrane

Viruses, 2021
Herpesvirus capsids are assembled in the nucleus and undergo a two-step process to cross the nuclear envelope. Capsids bud into the inner nuclear membrane (INM) aided by the nuclear egress complex (NEC) proteins UL31/34.

A physical link between the pseudorabies virus capsid and the nuclear egress complex. [PDF]

J Virol, 2011
ABSTRACT Following their assembly, herpesvirus capsids exit the nucleus by budding at the inner nuclear membrane. Two highly conserved viral proteins are required for this process, pUL31 and pUL34. In this report, we demonstrate that the pUL31 component of the pseudorabies virus nuclear egress complex is a conditional capsid-binding protein ...

Function of Torsin AAA+ ATPases in Pseudorabies Virus Nuclear Egress

Cells, 2020
Newly assembled herpesvirus nucleocapsids traverse the intact nuclear envelope by a vesicle-mediated nucleo-cytoplasmic transport for final virion maturation in the cytoplasm.

Cytomegaloviral proteins that associate with the nuclear lamina: components of a postulated nuclear egress complex

Journal of General Virology, 2009
The nuclear egress of cytomegaloviral capsids traversing the nuclear envelope is dependent on a locally restricted destabilization of the rigid nuclear lamina. It has been suggested that the multi-component nuclear egress complex (NEC) that is formed is comprised of both viral and cellular proteins which act to recruit lamin-phosphorylating protein ...
