    Cell-density independent increased lymphocyte production and loss rates post-autologous HSCT

    Mariona Baliu-Piqué, Vera van Hoeven ... Kiki Tesselaar
    Altered lymphocyte dynamics after hematopoietic stem cell transplantation cannot solely be explained by low lymphocyte numbers.

    Flux analysis of cholesterol biosynthesis in vivo reveals multiple tissue and cell-type specific pathways

    Matthew A Mitsche, Jeffrey G McDonald ... Jonathan C Cohen
    Cells use two interdigitated biosynthetic pathways that can be regulated independently to produce diverse bioactive sterols.

    Heterogeneity of proteome dynamics between connective tissue phases of adult tendon

    Howard Choi, Deborah Simpson ... Chavaunne T Thorpe
    Metabolic labelling reveals complex proteome dynamics in tendon, with faster turnover of proteins in the glycoprotein-rich interfascicular matrix compared to the collagen-rich fascicular matrix.

    Differential impact of BTK active site inhibitors on the conformational state of full-length BTK

    Raji E Joseph, Neha Amatya ... Amy Andreotti
    The first-in-class kinase inhibitor, Ibrutinib, destabilizes its autoinhibited Bruton’s tyrosine kinase (BTK) target, and a remote resistance mutation causes global structural changes that activate BTK catalytic activity.

    Tracing a protein’s folding pathway over evolutionary time using ancestral sequence reconstruction and hydrogen exchange

    Shion An Lim, Eric Richard Bolin, Susan Marqusee
    Pulsed-labeling hydrogen exchange on the ribonuclease H family show that the major folding intermediate is conserved over three billion years of evolution, but the path leading to this intermediate varies.

    Age-dependent changes in protein incorporation into collagen-rich tissues of mice by in vivo pulsed SILAC labelling

    Yoanna Ariosa-Morejon, Alberto Santos ... Tonia L Vincent
    Protein dynamics signatures in ageing collagen-rich tissues that are central to frequent age-related diseases such as osteoporosis and osteoarthritis.

    SARS-CoV-2 S protein:ACE2 interaction reveals novel allosteric targets

    Palur V Raghuvamsi, Nikhil K Tulsian ... Ganesh S Anand
    SARS-CoV-2 spike protein binding to receptor angiotensin-converting enzyme 2 allosterically enhances furin proteolysis at distal S1/S2 cleavage sites.

    Nucleotide binding to the ATP-cone in anaerobic ribonucleotide reductases allosterically regulates activity by modulating substrate binding

    Ornella Bimai, Ipsita Banerjee ... Derek T Logan
    The first structural and biochemical study of the role of the ATP-cone in anaerobic ribonucleotide reductases shows that dATP allosterically prevents transfer of a glycyl radical to the substrate.

    Decoupling of the onset of anharmonicity between a protein and its surface water around 200 K

    Lirong Zheng, Bingxin Zhou ... Liang Hong
    The dynamical transition between a protein and its surface water is decoupled.

    Disease-related mutations in PI3Kγ disrupt regulatory C-terminal dynamics and reveal a path to selective inhibitors

    Manoj K Rathinaswamy, Zied Gaieb ... John E Burke
    The c-terminus of PI3K plays a key role in regulating kinase activity, with c-terminal disease-linked mutations leading to either activation or inhibition, which reveal a path to specific inhibitors.
