    Histones: A new route to the nucleus

    Hongyu Bao, Hongda Huang
    A newly discovered pathway suggests histone proteins H3 and H4 are imported into the nucleus as individual units rather than joined together as heterodimers as was previously thought.

    Ligand-induced shifts in conformational ensembles that describe transcriptional activation

    Sabab Hasan Khan, Sean M Braet ... C Denise Okafor
    Transcriptional activity is characterized for five steroid receptors complexed with multiple ligands and it is shown that the extent of transcriptional activation in complexes is accurately described by conformational shifts in computationally-generated ensembles.

    Kinesin-1, -2, and -3 motors use family-specific mechanochemical strategies to effectively compete with dynein during bidirectional transport

    Allison M Gicking, Tzu-Chen Ma ... William O Hancock
    The motility of three different kinesin-dynein pairs were analyzed and found to be strikingly similar, suggesting that bidirectional transport is not regulated by motor type, but rather by scaffold, adapter, and regulatory proteins.

    Group II truncated haemoglobin YjbI prevents reactive oxygen species-induced protein aggregation in Bacillus subtilis

    Takeshi Imai, Ryuta Tobe ... Hisaaki Mihara
    The repair of oxidatively damaged proteins by the newly discovered activity in YjbI is important for the adaptation of Bacillus subtilis to oxidative environments.

    Solute exchange through gap junctions lessens the adverse effects of inactivating mutations in metabolite-handling genes

    Stefania Monterisi, Johanna Michl ... Pawel Swietach
    Imaging studies of connexin-coupled networks of colorectal cancer cells reveal that cells carrying a genetic defect in an essential metabolic pathway can be rescued by diffusive exchange with neighboring wild-type cells via gap junctions, particularly Cx26, thereby evading negative selection.

    Pathogenic variants of sphingomyelin synthase SMS2 disrupt lipid landscapes in the secretory pathway

    Tolulope Sokoya, Jan Parolek ... Joost CM Holthuis
    Organellar lipidomics and lipid reporter studies in intact cells reveal how disease-relevant mutations in a sphingolipid biosynthetic enzyme cause a wide-ranging perturbation of lipid distributions and membrane properties along the secretory pathway.

    Comprehensive phylogenetic analysis of the ribonucleotide reductase family reveals an ancestral clade

    Andrew A Burnim, Matthew A Spence ... Nozomi Ando
    A large-scale phylogenetic inference of the ribonucleotide reductase family reveals a new distinct clade with implications on how nature adapted to environmental changes.

    Targeting A-kinase anchoring protein 12 phosphorylation in hepatic stellate cells regulates liver injury and fibrosis in mouse models

    Komal Ramani, Nirmala Mavila ... Eki Seki
    Site-specific phosphorylation of the A-kinase anchoring protein 12 (AKAP12) in hepatic stellate cells modulates its scaffolding function and promotes liver fibrosis.

    S6K1 phosphorylates Cdk1 and MSH6 to regulate DNA repair

    Adi Amar-Schwartz, Vered Ben Hur ... Rotem Karni
    Unbiased proteomics and molecular analysis revealed a new role for S6K1 in regulating DNA repair through the orchestrated phosphorylation of CDK1 and MSH6. The findings may explain why RPS6KB1 gene amplification contributed to breast cancer drug resistance.

    Distinct architectural requirements for the parS centromeric sequence of the pSM19035 plasmid partition machinery

    Andrea Volante, Juan Carlos Alonso, Kiyoshi Mizuuchi
    Unique sequence feature requirements for the plasmid centromere pSM19035-parS for ParApSM-ATPase activation byribbon-helix-helix-ParBpSM, a non-CTPase centromere-binding protein, evince complex interaction gymnastics among the three reaction components necessary for plasmid partition, which is distinct from ParABS-systems involving helix-turn-helix-ParB-CTPases.
