    Structural characterization of NrnC identifies unifying features of dinucleases

    Justin D Lormand, Soo-Kyoung Kim ... Holger Sondermann
    Dinucleases, specialized enzymes that catalyze the final step in RNA degradation, have evolved independently and repeatedly to fulfill essential roles in cell growth.

    zGrad is a nanobody-based degron system that inactivates proteins in zebrafish

    Naoya Yamaguchi, Tugba Colak-Champollion, Holger Knaut
    The F-box/anti-GFP nanobody fusion protein zGrad depletes GFP-tagged proteins with spatial and temporal control in zebrafish.

    Heparin-binding motif mutations of human diamine oxidase allow the development of a first-in-class histamine-degrading biopharmaceutical

    Elisabeth Gludovacz, Kornelia Schuetzenberger ... Thomas Boehm
    Because heparin-binding motif mutations of human diamine oxidase (hDAO) block cellular uptake and strongly decrease clearance in vivo, modified recombinant hDAO might be a good candidate for the treatment of symptoms induced by excessive endogenous histamine release.

    Human DNA2 possesses a cryptic DNA unwinding activity that functionally integrates with BLM or WRN helicases

    Cosimo Pinto, Kristina Kasaciunaite ... Petr Cejka
    The nuclease of hDNA2 limits its processive DNA unwinding capacity; the helicase function becomes stimulatory when hDNA2 is in complex with BLM or WRN helicase to degrade dsDNA.

    Stem cell-derived cranial and spinal motor neurons reveal proteostatic differences between ALS resistant and sensitive motor neurons

    Disi An, Ryosuke Fujiki ... Esteban Orlando Mazzoni
    Stem cell-derived motor neurons with differential ALS vulnerability identified proteasome activity as a possible mechanism that explains their differential sensitivity.

    KHNYN is essential for the zinc finger antiviral protein (ZAP) to restrict HIV-1 containing clustered CpG dinucleotides

    Mattia Ficarelli, Harry Wilson ... Chad M Swanson
    KHNYN, a putative endoribonuclease, interacts with the zinc-finger antiviral protein (ZAP) and is required for the inhibition of HIV replication and RNA abundance by CpG dinucleotides.

    Comprehensive re-analysis of hairpin small RNAs in fungi reveals loci with conserved links

    Nathan R Johnson, Luis F Larrondo ... Elena A Vidal
    A critical assessment of published microRNA/microRNA-like provides clues on features and conservation of these hairpin RNAs in fungi in addition to a centralized loci annotation resource for the community.

    Host-microbiome metabolism of a plant toxin in bees

    Erick VS Motta, Alejandra Gage ... Nancy Moran
    The bee gut microbiota contributes to the metabolism of the cyanogenic glycoside amygdalin.

    Recurrent circuitry is required to stabilize piriform cortex odor representations across brain states

    Kevin A Bolding, Shivathmihai Nagappan ... Kevin M Franks
    Intracortical circuits in mouse olfactory cortex stabilize odor-evoked activity patterns when upstream inputs, from olfactory bulb, become degraded under anesthesia.
