What the literature leaves open

    SMARTFlexDB: a paired apo–holo RNA structure database and analysis platform for RNA conformational flexibility and small-molecule recognition · 2026 · DOI

  • Existing structural resources provide only static RNA-ligand snapshots without connecting ligand-bound to ligand-free conformations. The lack of paired structural information hinders the understanding of RNA-ligand recognition.

  • Existing classification methods often rely on secondary or tertiary RNA structures, which are computationally expensive to predict and prone to errors. The limitations of existing classification methods lead to a need for a more efficient and accurate approach. The diverse nature of non-coding RNAs makes their classification a challenging task.

    NCC—An Efficient Deep Learning Architecture for Non-Coding RNA Classification · 2025 · DOI

  • Yet how it acts at the level of individual mRNAs remains unclear, with competing models arguing that Nsp1 blocks translation initiation, stalls ribosome elongation, cleaves mRNA, or does all three.

    Live-cell, single-molecule imaging resolves the dual nature of mRNA silencing by SARS-CoV-2 Nsp1 · 2026 · DOI

  • Backbone-first approaches generate geometry before sequence assignment, yet how to transfer relational information to sequence design remains unclear.

    RiboCouple links RNA backbone generation to sequence design through a learned interaction topology · 2026 · DOI

  • Slowly translated codons are overrepresented among the first approximately 30 codons of natural genes across all domains of life, yet the functional basis for this conserved feature remains incompletely understood.

  • These findings are insufficient to overturn the core principle of the Central Dogma, but they provide a new perspective on information flow from proteins to nucleic acids, and offer novel insights into intracellular information transmission and the potential mechanisms underlying disease development.

    A New Perspective on Information Transfer from Proteins to Nucleic Acids · 2026 · DOI

  • Yet, the role of these RP defects in dysregulation of the ribosomal translation function remains poorly understood.

    Expanding the human proteome with microproteins and peptideins · 2026 · DOI

  • The mechanism by which ppGpp adjusts RNAP elongation rates remains poorly understood. Prior work has not fully elucidated the effects of ppGpp on RNA polymerase pausing and nucleotide addition.

    ppGpp regulates transcription elongation via direct and indirect inputs to RNA polymerase pausing and nucleotide addition · 2026 · DOI

    Pan-Viral Conformational Landscapes of Frameshifting Elements Reveal Length-Dependent Plasticity and Antisense-Driven Structural Reprogramming · 2026 · DOI

  • Fewer ARS-protein interactions are known in archaea and bacteria. The interactions in these domains are mostly focused on connections that occur during translation.

    The Aminoacyl-tRNA Synthetases and Their Protein–Protein Interactions · 2026 · DOI

  • Although they all bind to the E site of the ribosome, some bacterial ABC-Fs confer resistance to ribosome-targeting antibiotics, while housekeeping members have poorly defined roles.

    The ABC-F protein Uup, Rescues Stalled Ribosomal Termination Complexes to Modulate DNA Maintenance · 2026 · DOI

  • The detection of the ppGpp effect on TL folding relies on distributions of ePEC conformations that include TL-folded states and not direct detection of ppGpp action on the NAC. Computational sorting of particles to distinct conformational states during cryo-EM data processing is inherently limited by the signal-to-noise ratio of the underlying individual particle images.

    ppGpp regulates transcription elongation via direct and indirect inputs to RNA polymerase pausing and nucleotide addition · 2026 · DOI
