Cytosolic 2-Cys peroxiredoxins can enable, rather than compete with, rapid thiol oxidation by relaying H2O2-derived oxidizing equivalents to other proteins, suggesting a broadened role for peroxiredoxins as sensors and transmitters of H2O2 signals.
A selective small-molecule degrader of CDK9 was generated by conjugating an imide to SNS-032, a promiscuous ATP-site-directed CDK binder. The pharmacological consequences of CDK9 degradation versus inhibition were compared.
A modular protein expression system enables the structural and functional characterization of human glycosyltransferases, glycoside hydrolases and other carbohydrate-modifying enzymes.
Glycosylation of Notch receptors regulates ligand-induced Notch signaling, which is essential for normal development in animals. Fucose analogs targeting Notch glycosylation serve as ligand-specific Notch inhibitors and facilitate the understanding of how O-glycan regulates Notch–ligand interactions.
Modification of folded proteins at will, within any sequence context, remains an elusive goal. A proteome-wide screening approach has now identified a set of protein ligases that enables conjugation of peptides to almost any protein N terminus, overcoming longstanding limitations in protein engineering.
A potent inhibitor of the conditionally essential mitochondrial phosphate carrier protein Mir1 in the fungi Candida albicans diminishes mitochondrial oxygen consumption and causes dramatic changes in concentrations of citrate and succinate.
D2 dopamine receptor ligands biased for b-arrestin recruitment were developed based on a receptor homology model that identified conserved ligand contacts within the TM5 and EL2 regions as important for biased signaling.
Two complementary coiled-coil peptides and a bacterial microcompartment shell protein are combined to construct cytoscaffolds within Escherichia coli cells. Targeting enzymes to the cytoplasmic scaffold results in colocalization and improved metabolic flux.
A selective inhibitor of the deubiquitinase USP7 binds an allosteric site to inhibit its MDM2-stabilizing activity, resulting in stabilization of p53 and p21, which confers hypersensitivity to cancer cells for killing by the compound.
Selections with a phage-displayed antibody library against an existing protein–small-molecule complex enabled the generation of antibody-based chemically induced dimerizers (AbCIDs) with the properties necessary for use in regulating cell therapies.
Protein O-fucosyltransferase 1 (Pofut1) regulates Notch activity by adding O-fucose residues to its extracellular domain. Fucose analogs were identified that inhibited Delta-mediated Notch binding and activation but spared Jagged1-mediated signaling.
Direct conversion of 5-fdC into dC by C–C bond breakage is revealed by metabolic tracing studies through incorporation of synthetic stable isotope- and (R)-2′-fluorine-labeled dC and fdC derivatives into the genome of cultured mammalian cells.
