  1. The IFIT2-IFIT3 antiviral complex targets short 5' untranslated regions on viral mRNAs for translation inhibition.

    Nature microbiology · 2025 · 10(11): 2934-2948

    Recognition of foreign RNA is critical for the innate immune response to viruses. Interferon (IFN)-induced proteins with tetratricopeptide repeats (IFIT) 2 and 3 are highly upregulated following viral infection, but mechanistic insight into their antiviral role is lacking. Here we …

  2. Short 5' UTRs serve as a marker for viral mRNA translation inhibition by the IFIT2-IFIT3 antiviral complex.

    bioRxiv : the preprint server for biology · 2025

    Recognition of "non-self" nucleic acids, including cytoplasmic dsDNA, dsRNA, or mRNAs lacking proper 5' cap structures, is critical for the innate immune response to viruses. Here, we demonstrate that short 5' untranslated regions (UTRs), a characteristic of many viral mRNAs, …

  3. A phage nucleus-associated RNA-binding protein is required for jumbo phage infection.

    Nucleic acids research · 2024 · 52(8): 4440-4455

    Large-genome bacteriophages (jumbo phages) of the proposed family Chimalliviridae assemble a nucleus-like compartment bounded by a protein shell that protects the replicating phage genome from host-encoded restriction enzymes and DNA-targeting CRISPR-Cas nucleases. While the nuclear shell provides broad protection against …

  4. Transcriptome regulation by PARP13 in basal and antiviral states in human cells.

    iScience · 2024 · 27(4): 109251

    The RNA-binding protein PARP13 is a primary factor in the innate antiviral response, which suppresses translation and drives decay of bound viral and host RNA. PARP13 interacts with many proteins encoded by interferon-stimulated genes (ISG) to activate antiviral pathways including …
