  1. ESCAPE: assigning site-specific activity to covalent ligands in cells by prime editing.

    bioRxiv : the preprint server for biology · 2026

    Chemical proteomics has identified covalent ligands targeting cysteine residues across many hundreds of human proteins. The functional effects of these liganding events, however, remain challenging to assign at scale. Here we describe ESCAPE (Endogenous Site-specific Competition Assays using Prime Editors), …

  2. Structural and mechanistic analysis of covalent ligands targeting the RNA-binding protein NONO.

    Cell chemical biology · 2026 · 33(2): 256-267.e11

    RNA-binding proteins (RBPs) play important roles in mRNA transcription, processing, and translation. Chemical tools are lacking for RBPs, which has hindered efforts to perturb and understand RBP function in cells. We previously described a chloroacetamide compound (R)-SKBG-1 that covalently binds …

  3. Structural and mechanistic analysis of covalent ligands targeting the RNA-binding protein NONO.

    bioRxiv : the preprint server for biology · 2025

    RNA-binding proteins (RBPs) play important roles in mRNA transcription, processing, and translation. Chemical tools are lacking for RBPs, which has hindered efforts to perturb and understand RBP function in cells. We recently reported a chloroacetamide compound ( <i>R</i> )-SKBG-1 that …

  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. Proteomic discovery of chemical probes that perturb protein complexes in human cells.

    Molecular cell · 2023 · 83(10): 1725-1742.e12

    Most human proteins lack chemical probes, and several large-scale and generalizable small-molecule binding assays have been introduced to address this problem. How compounds discovered in such "binding-first" assays affect protein function, nonetheless, often remains unclear. Here, we describe a "function-first" …
