Mechanism of Viral Glycoprotein Targeting by Membrane-Associated RING-CH Proteins

mBio, 2021
Viral envelope glycoproteins are an important structural component on the surfaces of enveloped viruses that direct virus binding and entry and also serve as targets for the host adaptive immune response.

Mechanistic Analysis of the Broad Antiretroviral Resistance Conferred by HIV-1 Envelope Glycoprotein Mutations

mBio, 2021
Although combination antiretroviral (ARV) therapy is highly effective in controlling the progression of HIV disease, drug resistance can be a major obstacle. Recent findings suggest that resistance can develop without ARV target gene mutations.

Does the Cytoplasmic Tail Matter? Mechanism of Viral Envelope Glycoprotein Targeting by Membrane-Associated-RING-CH (MARCH) Proteins

Proceedings, 2020
The MARCH family of RING-finger E3 ubiquitin ligases comprise 11 members that have been reported to play a variety of roles in the downregulation of cell-surface proteins involved in adaptive immunity.

Generation and validation of a highly sensitive bioluminescent HIV-1 reporter vector that simplifies measurement of virus release

Retrovirology, 2020
Background The continued persistence of HIV-1 as a public health concern due to the lack of a cure calls for the development of new tools for studying replication of the virus.

SARS-CoV-2: from its discovery to genome structure, transcription, and replication

Cell & Bioscience, 2021
SARS-CoV-2 is an extremely contagious respiratory virus causing adult atypical pneumonia COVID-19 with severe acute respiratory syndrome (SARS). SARS-CoV-2 has a single-stranded, positive-sense RNA (+RNA) genome of ~ 29.9 kb and exhibits significant ...

Human Papillomavirus Type 16 Circular RNA Is Barely Detectable for the Claimed Biological Activity

mBio, 2022
Human papillomavirus type 16 (HPV16) E7 oncoprotein plays an essential role in cervical carcinogenesis and is encoded predominantly by an E6*I mRNA through alternative RNA splicing of a P97 promoter-transcribed bicistronic E6E7 pre-mRNA.

Revisiting and corrections to the annotated SRSF3 (SRp20) gene structure and RefSeq sequences from the human and mouse genomes

Cell Insight, 2023
SRSF3 (SRp20) is the smallest member of the serine/arginine (SR)-rich protein family. We found the annotated human SRSF3 and mouse Srsf3 RefSeq sequences are much larger than the detected SRSF3/Srsf3 RNA size by Northern blot.

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,

HIV-1 Natural Antisense Transcription and Its Role in Viral Persistence

Viruses, 2021
Natural antisense transcripts (NATs) represent a class of RNA molecules that are transcribed from the opposite strand of a protein-coding gene, and that have the ability to regulate the expression of their cognate protein-coding gene via multiple ...

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.
