    Structure and dynamics of the chromatin remodeler ALC1 bound to a PARylated nucleosome

    Luka Bacic et al.
    Analysis of conformational heterogeneity in cryo-EM data by a recently developed deep learning method reveals the structure and dynamics of the oncogenic chromatin remodeler ALC1 bound to a poly-ADP-ribosylated nucleosome.

    Maturation of Purkinje cell firing properties relies on neurogenesis of excitatory neurons

    Meike E van der Heijden et al.
    Intersectional genetics show that excitatory neurons are essential for the functional and anatomical maturation of cerebellar circuits in mice.

    SUV39 SET domains mediate crosstalk of heterochromatic histone marks

    Alessandro Stirpe et al.
    Clr4, a highly conserved SUV39 histone methyltransferase, requires its SET domain to sense histone H3K14 ubiquitination in order to maintain heterochromatin and H3K9 methylation.

    Regulation of human mTOR complexes by DEPTOR

    Matthias Wälchli et al.
    Structural and functional analysis reveals the mechanistic basis for mammalian target of rapamycin (mTOR)-dependent roles of DEP domain-containing mTOR interacting protein (DEPTOR) in cancer and metabolic regulation.

    Bipartite binding and partial inhibition links DEPTOR and mTOR in a mutually antagonistic embrace

    Maren Heimhalt et al.
    The inhibitory protein DEPTOR make two widely separated interactions with mTOR that are both necessary for its unique partial mTOR inhibition, and DEPTOR is a more potent inhibitor of mutation- or RHEB-activated mTORC1 than basal mTORC1.

    Hsp40s play complementary roles in the prevention of tau amyloid formation

    Rose Irwin et al.
    Chaperones from different families and classes synergistically target different stages of tau aggregation, thus preventing pathological amyloid formation.

    The structure of photosystem I from a high-light-tolerant cyanobacteria

    Zachary Dobson et al.
    The necessity of studying extremophile organisms is exemplified by the structure of photosystem I from a high-light tolerant cyanobacteria, demonstrating the relationship between the structure and function in photosystem I.

    Linker histone H1.8 inhibits chromatin binding of condensins and DNA topoisomerase II to tune chromosome length and individualization

    Pavan Choppakatla et al.
    Linker histone H1.8 shapes mitotic chromosomes by tuning the number and size of condensin-dependent DNA loops and suppressing condensin and DNA topoisomerase II-dependent individualization.

    Naa12 compensates for Naa10 in mice in the amino-terminal acetylation pathway

    Hyae Yon Kweon et al.
    Mice doubly deficient for Naa10 and Naa12 display embryonic lethality, with both enzymes compensating for each other with amino-terminal acetylation of proteins in mouse development.

    Selective dephosphorylation by PP2A-B55 directs the meiosis I-meiosis II transition in oocytes

    S Zachary Swartz et al.
    Time-course phosphoproteomics reveals that selective dephosphorylation is critical for directing the MI/MII transition and that, through its inherent phospho-threonine preference, PP2A-B55 imposes specific phosphoregulated behaviors that distinguish the two meiotic divisions.
