Plasma Membrane Anchoring and Gag:Gag Multimerization on Viral RNA Are Critical Properties of HIV-1 Gag Required To Mediate Efficient Genome Packaging

mBio, 2021
Human immunodeficiency virus type 1 (HIV-1) Gag selects and packages the HIV RNA genome during virus assembly. However, HIV-1 RNA constitutes only a small fraction of the cellular RNA.

Host protein kinases required for SARS-CoV-2 nucleocapsid phosphorylation and viral replication

Science Signaling, 2022
Multiple coronaviruses have emerged independently in the past 20 years that cause lethal human diseases. Although vaccine development targeting these viruses has been accelerated substantially, there remain patients requiring treatment who cannot be ...

Adaptation of HIV-1/HIV-2 Chimeras with Defects in Genome Packaging and Viral Replication

mBio, 2022
Frequent recombination is a hallmark of retrovirus replication. In rare cases, recombination occurs between distantly related retroviruses, generating novel viruses that may significantly impact viral evolution and public health.

Transcription Start Site Heterogeneity and Preferential Packaging of Specific Full-Length RNA Species Are Conserved Features of Primate Lentiviruses

Microbiology Spectrum, 2022
HIV-1 must package its RNA genome to generate infectious viruses. Recent studies have revealed that during genome packaging, HIV-1 not only excludes cellular mRNAs, but also distinguishes among full-length viral RNAs. Using NL4-3 and MAL molecular clones,

SARS-CoV-2 hijacks folate and one-carbon metabolism for viral replication

Nature Communications, 2021
The recently identified Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the cause of the COVID-19 pandemic. How this novel beta-coronavirus virus, and coronaviruses more generally, alter cellular metabolism to support massive production ...

SARS-CoV-2 nucleocapsid protein impairs stress granule formation to promote viral replication

Cell Discovery, 2021
The newly emerging coronavirus SARS-CoV-2 causes severe lung disease and substantial mortality. How the virus evades host defense for efficient replication is not fully understood.

Endocytosis in Viral Replication [PDF]

Traffic, 2000
Although initially recognised as essential for the entry of certain viruses, endocytosis is now known to also play important roles in the replication of, and adaptation to, the host cell of a number of viruses. Here we consider several aspects of this association and recent results that have emerged to support this view.

Boceprevir, GC-376, and calpain inhibitors II, XII inhibit SARS-CoV-2 viral replication by targeting the viral main protease

Cell Research, 2020
A new coronavirus SARS-CoV-2, also called novel coronavirus 2019 (2019-nCoV), started to circulate among humans around December 2019, and it is now widespread as a global pandemic.

Cytoplasmic Viral Replication Complexes [PDF]

Cell Host & Microbe, 2010
Many viruses that replicate in the cytoplasm compartmentalize their genome replication and transcription in organelle-like structures that enhance replication efficiency and protection from host defenses. In particular, recent studies with diverse positive-strand RNA viruses have further elucidated the ultrastructure of membrane-bound RNA replication ...

Viral Macrodomains: Unique Mediators of Viral Replication and Pathogenesis [PDF]

Trends in Microbiology, 2017
Viruses from the Coronaviridae, Togaviridae, and Hepeviridae families ​all contain genes that encode a conserved protein domain, called a macrodomain; however, the role of this domain during infection has remained enigmatic. The recent discovery that mammalian macrodomain proteins enzymatically remove ADP-ribose, a common post-translation modification,
