  • Organelle membrane-specific chemical labeling and dynamic imaging in living cells
    Nat. Chem. Biol. (IF 12.587) Pub Date : 2020-09-21
    Tomonori Tamura; Alma Fujisawa; Masaki Tsuchiya; Yuying Shen; Kohjiro Nagao; Shin Kawano; Yasushi Tamura; Toshiya Endo; Masato Umeda; Itaru Hamachi

    Lipids play crucial roles as structural elements, signaling molecules and material transporters in cells. However, the functions and dynamics of lipids within cells remain unclear because of a lack of methods to selectively label lipids in specific organelles and trace their movement by live-cell imaging. We describe here a technology for the selective labeling and fluorescence imaging (microscopic

    The immunomodulatory drug (IMiD) thalidomide and its derivatives lenalidomide and pomalidomide are therapeutic agents used in the treatment of multiple myeloma. Although pomalidomide offers considerable clinical benefits to patients with lenalidomide-resistant multiple myeloma, the molecular mechanisms underlying its superior efficacy remain unclear. Here we show that ARID2, a component of the polybromo-associated

    Many bacterial pathogens secrete virulence factors, also known as effector proteins, directly into host cells. These effectors suppress pro-inflammatory host signaling while promoting bacterial infection. A particularly interesting subset of effectors post-translationally modify host proteins using novel chemistry that is not otherwise found in the mammalian proteome, which we refer to as ‘orthogonal

    Many intracellular proteins are modified by N-acetylglucosamine, a post-translational modification termed O-GlcNAc. This modification is found on serine and threonine side chains and has the potential to regulate signaling pathways through interplay with phosphorylation. Here, we discover and characterize one such example. We find that O-GlcNAc levels control the sensitivity of fibroblasts to actin

  • Sterols in an intramolecular channel of Smoothened mediate Hedgehog signaling

    Xiaofeng Qi; Lucas Friedberg; Ryan De Bose-Boyd; Tao Long; Xiaochun Li

    Smoothened (SMO), a class Frizzled G protein-coupled receptor (class F GPCR), transduces the Hedgehog signal across the cell membrane. Sterols can bind to its extracellular cysteine-rich domain (CRD) and to several sites in the seven transmembrane helices (7-TMs) of SMO. However, the mechanism by which sterols regulate SMO via multiple sites is unknown. Here we determined the structures of SMO–Gi complexes

    Compared with green fluorescent protein-based biosensors, red fluorescent protein (RFP)-based biosensors are inherently advantageous because of reduced phototoxicity, decreased autofluorescence and enhanced tissue penetration. However, existing RFP-based biosensors often suffer from small dynamic ranges, mislocalization and undesired photoconversion. In addition, the choice of available RFP-based biosensors

    The direct C–H carboxylation of aromatic compounds is an attractive route to the corresponding carboxylic acids, but remains challenging under mild conditions. It has been proposed that the first step in anaerobic microbial degradation of recalcitrant aromatic compounds is a UbiD-mediated carboxylation. In this study, we use the UbiD enzyme ferulic acid decarboxylase (Fdc) in combination with a carboxylic

  • NADP modulates RNA m6A methylation and adipogenesis via enhancing FTO activity.

    Metabolism is often regulated by the transcription and translation of RNA. In turn, it is likely that some metabolites regulate enzymes controlling reversible RNA modification, such as N6-methyladenosine (m6A), to modulate RNA. This hypothesis is at least partially supported by the findings that multiple metabolic diseases are highly associated with fat mass and obesity-associated protein (FTO), an

    Thermodynamic principles are used to map the phase behavior of a tunable protein-binding system under crowded cellular conditions. This study marks a substantial step forward in relating molecular interactions to material properties and cellular processes involving protein self-assembly.

    Rho family GTPases regulate cell behaviors through complex signaling networks that act on rapid timescales in subcellular spatial domains. New live-cell biosensors and analytical methods now provide critical tools to dissect Rho GTPase regulation and to better understand cellular information processing.

  • Chemical strategies to overcome resistance against targeted anticancer therapeutics.
    Nat. Chem. Biol. (IF 12.587) Pub Date : 2020-07-21
    Rudolf Pisa,Tarun M Kapoor

    Emergence of resistance is a major factor limiting the efficacy of molecularly targeted anticancer drugs. Understanding the specific mutations, or other genetic or cellular changes, that confer drug resistance can help in the development of therapeutic strategies with improved efficacies. Here, we outline recent progress in understanding chemotype-specific mechanisms of resistance and present chemical

    Mass spectrometry-based discovery proteomics is an essential tool for the proximal readout of cellular drug action. Here, we apply a robust proteomic workflow to rapidly profile the proteomes of five lung cancer cell lines in response to more than 50 drugs. Integration of millions of quantitative protein–drug associations substantially improved the mechanism of action (MoA) deconvolution of single

  • Pharmacologic IRE1/XBP1s activation confers targeted ER proteostasis reprogramming.

    Activation of the IRE1/XBP1s signaling arm of the unfolded protein response (UPR) is a promising strategy to correct defects in endoplasmic reticulum (ER) proteostasis implicated in diverse diseases. However, no pharmacologic activators of this pathway identified to date are suitable for ER proteostasis remodeling through selective activation of IRE1/XBP1s signaling. Here, we use high-throughput screening

    The NUDIX hydrolase NUDT15 was originally implicated in sanitizing oxidized nucleotides, but was later shown to hydrolyze the active thiopurine metabolites, 6-thio-(d)GTP, thereby dictating the clinical response of this standard-of-care treatment for leukemia and inflammatory diseases. Nonetheless, its physiological roles remain elusive. Here, we sought to develop small-molecule NUDT15 inhibitors to

    Drugs that promote the association of protein complexes are an emerging therapeutic strategy. We report discovery of a G protein-coupled receptor (GPCR) ligand that stabilizes an active state conformation by cooperatively binding both the receptor and orthosteric ligand, thereby acting as a ‘molecular glue’. LSN3160440 is a positive allosteric modulator of the GLP-1R optimized to increase the affinity

    Stunning advances in the structural biology of multicomponent biomolecular complexes (MBCs) have ushered in an era of intense, structure-guided mechanistic and functional studies of these complexes. Nonetheless, existing methods to site-specifically conjugate MBCs with biochemical and biophysical labels are notoriously impracticable and/or significantly perturb MBC assembly and function.
