Highly Expressed Soluble Recombinant Anti-GFP VHHs in Escherichia coli via Optimized Signal Peptides, Strains, and Inducers

open access: yesFrontiers in Molecular Biosciences, 2022
Antigen-binding variable domains of the H chain of heavy-chain antibodies (VHHs), also known as nanobodies (Nbs), are of great interest in imaging technique, disease prevention, diagnosis, and therapy.

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

open access: yesmBio, 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.

Coding and noncoding transcriptomes of NODULIN HOMEOBOX (NDX)-deficient Arabidopsis inflorescence

open access: yesScientific Data, 2023
Arabidopsis NODULIN HOMEOBOX (NDX) is a plant-specific transcriptional regulator whose role in small RNA biogenesis and heterochromatin homeostasis has recently been described. Here we extend our previous transcriptomic analysis to the flowering stage of

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

open access: yesmBio, 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.

Development of a Cell-Based Luciferase Complementation Assay for Identification of SARS-CoV-2 3CLpro Inhibitors

open access: yesViruses, 2021
The 3C-like protease (3CLpro) of SARS-CoV-2 is considered an excellent target for COVID-19 antiviral drug development because it is essential for viral replication and has a cleavage specificity distinct from human proteases.

NODULIN HOMEOBOX is required for heterochromatin homeostasis in Arabidopsis

open access: yesNature Communications, 2022
Arabidopsis NDX was previously reported as a regulator of euchromatic gene expression. Here the authors show that NDX functions at pericentromeric regions and regulates heterochromatin homeostasis by controlling siRNA production and non-CG methylation.

Evolution of the recombination regulator PRDM9 in minke whales

open access: yesBMC Genomics, 2022
Background PRDM9 is a key regulator of meiotic recombination in most metazoans, responsible for reshuffling parental genomes. During meiosis, the PRDM9 protein recognizes and binds specific target motifs via its array of C2H2 zinc-fingers encoded by a ...

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

open access: yesMicrobiology 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,

Personalized genome structure via single gamete sequencing

open access: yesGenome Biology, 2021
Genetic maps have been fundamental to building our understanding of disease genetics and evolutionary processes. The gametes of an individual contain all of the information required to perform a de novo chromosome-scale assembly of an individual’s genome,

Impact of Nuclear Export Pathway on Cytoplasmic HIV-1 RNA Transport Mechanism and Distribution

open access: yesmBio, 2020
HIV-1 full-length RNA (referred to as HIV-1 RNA here) serves as the viral genome in virions and as a template for Gag/Gag-Pol translation. We previously showed that HIV-1 RNA, which is exported via the CRM1 pathway, travels in the cytoplasm mainly ...
