  1. KIF5A binds RNA to orchestrate synaptic mRNA localization and stress granules in ALS.

    bioRxiv : the preprint server for biology · 2025

    Neuronal health depends on the precise transport and local translation of mRNAs to maintain synaptic function across highly polarized cellular architecture. While kinesin motor proteins are known to mediate mRNA transport, the specificity and direct involvement of individual kinesins as …

  2. RNA triggers chronic stress during neuronal aging.

    bioRxiv : the preprint server for biology · 2025

    Neurodegenerative diseases are linked with dysregulation of the integrated stress response (ISR), which coordinates cellular homeostasis during and after stress events. Cellular stress can arise from several sources, but there is significant disagreement about which stress might contribute to aging …

    PMID 40799579 DOI ↗

  3. LARP4 is an RNA-binding protein that binds nuclear-encoded mitochondrial mRNAs to promote mitochondrial function.

    RNA (New York, N.Y.) · 2024 · 30(3): 223-239

    Mitochondria-associated RNA-binding proteins (RBPs) have emerged as key contributors to mitochondrial biogenesis and homeostasis. With few examples known, we set out to identify RBPs that regulate nuclear-encoded mitochondrial mRNAs (NEMmRNAs). Our systematic analysis of RNA targets of 150 RBPs identified …

  4. Remodeling oncogenic transcriptomes by small molecules targeting NONO.

    Nature chemical biology · 2023 · 19(7): 825-836

    Much of the human proteome is involved in mRNA homeostasis, but most RNA-binding proteins lack chemical probes. Here we identify electrophilic small molecules that rapidly and stereoselectively decrease the expression of transcripts encoding the androgen receptor and its splice variants …

    PMID 36864190 DOI ↗

  5. Splicing factor SRSF1 deficiency in the liver triggers NASH-like pathology and cell death.

    Nature communications · 2023 · 14(1): 551

    Regulation of RNA processing contributes profoundly to tissue development and physiology. Here, we report that serine-arginine-rich splicing factor 1 (SRSF1) is essential for hepatocyte function and survival. Although SRSF1 is mainly known for its many roles in mRNA metabolism, it …

    PMID 36759613 DOI ↗

  6. RNA binding protein DDX5 restricts RORγt<sup>+</sup> T<sub>reg</sub> suppressor function to promote intestine inflammation.

    Science advances · 2023 · 9(5): eadd6165

    Retinoid-related orphan receptor (RAR) gamma (RORγt)-expressing regulatory T cells (RORγt<sup>+</sup> T<sub>regs</sub>) play pivotal roles in preventing T cell hyperactivation and maintaining tissue homeostasis, in part by secreting the anti-inflammation cytokine interleukin-10 (IL-10). Here, we report that hypoxia-induced factor 1α (HIF1α) …

    PMID 36724232 DOI ↗

  7. Aging RNA granule dynamics in neurodegeneration.

    Frontiers in molecular biosciences · 2022 · 9: 991641

    Disordered RNA-binding proteins and repetitive RNA sequences are the main genetic causes of several neurodegenerative diseases, including amyotrophic lateral sclerosis and Huntington's disease. Importantly, these components also seed the formation of cytoplasmic liquid-like granules, like stress granules and P bodies. …

    PMID 36188213 DOI ↗

  8. VPS13A and VPS13C Influence Lipid Droplet Abundance.

    Contact (Thousand Oaks (Ventura County, Calif.)) · 2022 · 5: 25152564221125613

    Lipid transfer proteins mediate the exchange of lipids between closely apposed membranes at organelle contact sites and play key roles in lipid metabolism, membrane homeostasis, and cellular signaling. A recently discovered novel family of lipid transfer proteins, which includes the …

    PMID 36147729 DOI ↗

  9. Zmat3 Is a Key Splicing Regulator in the p53 Tumor Suppression Program.

    Molecular cell · 2020 · 80(3): 452-469.e9

    Although TP53 is the most commonly mutated gene in human cancers, the p53-dependent transcriptional programs mediating tumor suppression remain incompletely understood. Here, to uncover critical components downstream of p53 in tumor suppression, we perform unbiased RNAi and CRISPR-Cas9-based genetic screens …

    PMID 33157015 DOI ↗

  10. A role for alternative splicing in circadian control of exocytosis and glucose homeostasis.

    Genes & development · 2020 · 34(15-16): 1089-1105

    The circadian clock is encoded by a negative transcriptional feedback loop that coordinates physiology and behavior through molecular programs that remain incompletely understood. Here, we reveal rhythmic genome-wide alternative splicing (AS) of pre-mRNAs encoding regulators of peptidergic secretion within pancreatic …

    PMID 32616519 DOI ↗

  11. Disruption of RNA Metabolism in Neurological Diseases and Emerging Therapeutic Interventions.

    Neuron · 2019 · 102(2): 294-320

    RNA binding proteins are critical to the maintenance of the transcriptome via controlled regulation of RNA processing and transport. Alterations of these proteins impact multiple steps of the RNA life cycle resulting in various molecular phenotypes such as aberrant RNA …

  12. RNA-binding proteins in neurodegeneration: Seq and you shall receive.

    Trends in neurosciences · 2015 · 38(4): 226-36

    As critical players in gene regulation, RNA binding proteins (RBPs) are taking center stage in our understanding of cellular function and disease. In our era of bench-top sequencers and unprecedented computational power, biological questions can be addressed in a systematic, …
