    A divergent cyclin/cyclin-dependent kinase complex controls the atypical replication of a malaria parasite during gametogony and transmission

    Aurélia C Balestra, Mohammad Zeeshan ... Mathieu Brochet
    Multiple steps of the atypical cell cycles underlying Plasmodium gametogony are controlled by a divergent cyclin/cyclin-dependent complex.

    Cyclin D activates the Rb tumor suppressor by mono-phosphorylation

    Anil M Narasimha, Manuel Kaulich ... Steven F Dowdy
    The retinoblastoma tumor suppressor regulates cell cycle progression when it's in 14 mono-phosphorylated isoforms.

    Cyclin A/Cdk1 modulates Plk1 activity in prometaphase to regulate kinetochore-microtubule attachment stability

    Ana Maria G Dumitru, Scott F Rusin ... Duane A Compton
    Quantitative phosphoproteomics defines the substrates for Cyclin A/Cdk1 kinase during early mitosis and follow up studies validate that one identified substrate, MYPT1, influences the stability of k-MT attachments by regulating Plk1.

    Ordered dephosphorylation initiated by the selective proteolysis of cyclin B drives mitotic exit

    James Holder, Shabaz Mohammed, Francis A Barr
    Selective APC/C-mediated proteolysis of cyclin B drives progression through the metaphase-anaphase transition whilst wide-spread waves of dephosphorylation co-ordinate the subsequent events of mitotic exit.

    Cyclin F drives proliferation through SCF-dependent degradation of the retinoblastoma-like tumor suppressor p130/RBL2

    Taylor P Enrico, Wayne Stallaert ... Michael J Emanuele
    The SCF-family of ubiquitin ligases regulates the key cancer proliferation node by controlling the degradation of RB-like tumor suppressor RBL2/p130.

    Reprogramming of translation in yeast cells impaired for ribosome recycling favors short, efficiently translated mRNAs

    Swati Gaikwad, Fardin Ghobakhlou ... Alan G Hinnebusch
    A mutant impaired for ribosome recycling exhibits translational reprogramming wherein strong mRNAs outcompete weak mRNAs, also observed when preinitiation complexes are diminished by eIF2α phosphorylation or 40S ribosomal subunit depletion.

    Discovery of a molecular glue promoting CDK12-DDB1 interaction to trigger cyclin K degradation

    Lu Lv, Peihao Chen ... Ting Han
    High-throughput phenotypic screening followed by unbiased target identification reveals a new molecular glue HQ461 that induces CDK12-DDB1 interaction to promote degradation of Cyclin K via the ubiquitin proteasome system.

    Flexible use of memory by food-caching birds

    Marissa C Applegate, Dmitriy Aronov
    A novel laboratory paradigm for studying food-caching behavior in black-capped chickadees and contributions of memory to this behavior.

    Cyclin-dependent kinase control of motile ciliogenesis

    Eszter K Vladar, Miranda B Stratton ... Jeffrey D Axelrod
    Cyclin-dependentkinase 2 (Cdk2), the master regulator of S phase events during the cell cycle, controls the earliest step in the motile ciliogenesis pathway in quiescent multiciliatedairway epithelial cells.

    The effect of variation of individual infectiousness on SARS-CoV-2 transmission in households

    Tim K Tsang, Xiaotong Huang ... Benjamin John Cowling
    Household transmission modeling qualified variation of individual infectiousness among infected persons, which could be caused by both biological factors and host behaviors.
