A new method to understand protein dynamics and the regulation of cellular processes
1dCellular processes are regulated through the balance between protein shapes that confer active or inactive functions. In the complexity of cellular regulations, the preferred shape (or conformation) of a protein often depends on the binding of another molecule (called effector), thus implying that the same protein can exert distinct functions depending on the effector it binds to. At the molecular

Odlad svamp blir kugge i cirkulär matproduktion
1dStädernas matavfall kan bli odlingsbäddar för ostronskivling. Den köttiga koralltickan trivs på sågspån från svensk skog. Odlad svamp kan bli en nyckelspelare i så kallad cirkulär matproduktion, menar forskare vid SLU. Cirkulär livsmedelsproduktion handlar om att skapa ett system där avfall inte uppstår och resurser behålls i ett kretslopp. Och som dessutom kan ge vinster både för miljön och ekon

Variant PCGF1-PRC1 links PRC2 recruitment with differentiation-associated transcriptional inactivation at target genes
1dNature Communications, Published online: 09 September 2021; doi:10.1038/s41467-021-24894-z Polycomb repressive complexes (PRC1 and PRC2) repress genes that are crucial for development via epigenetic modifications; however, their role in differentiation is not well known. Here the authors reveal that a PCGF1-containing PRC1 variant facilitates exit from pluripotency by downregulating target genes
Climate warming promotes pesticide resistance through expanding overwintering range of a global pest
1dNature Communications, Published online: 09 September 2021; doi:10.1038/s41467-021-25505-7 Climate-driven range shifts may affect pesticide resistance. Here, the authors analyse experimentally parameterised and field-tested models to show that a cosmopolitan insect pest, the diamondback moth, is acquiring resistance against local pesticides through expanding overwintering range.
Locus specific epigenetic modalities of random allelic expression imbalance
1dNature Communications, Published online: 09 September 2021; doi:10.1038/s41467-021-25630-3 Some autosomal genes are expressed in a random monoallelic manner, but its extent and mechanisms have remained unclear. Here the authors show robust monoallelic expression in cell lines and mice, where the silent allele can be reexpressed using epidrugs. Further, they find these genes display various modali
Structural basis for the tryptophan sensitivity of TnaC-mediated ribosome stalling
1dNature Communications, Published online: 09 September 2021; doi:10.1038/s41467-021-25663-8 Bacteria adjust the expression of some of their metabolic enzymes through metabolite-sensing ribosome nascent chain complexes. Here the authors present a cryo-EM structure of an E. coli ribosome stalled during translation of the TnaC leader peptide and propose a model for L-Trp dependent ribosome stalling w
A barbed end interference mechanism reveals how capping protein promotes nucleation in branched actin networks
1dNature Communications, Published online: 09 September 2021; doi:10.1038/s41467-021-25682-5 The assembly of branched actin networks depends on the heterodimeric capping protein CP/CapZ. Combining cryoEM, in vitro reconstitution and cell biological assays, the authors show that CP not only prevents actin filament elongation but also selectively masks actin filament ends to promote nucleation.
DnaJC7 binds natively folded structural elements in tau to inhibit amyloid formation
1dNature Communications, Published online: 09 September 2021; doi:10.1038/s41467-021-25635-y Protein binding by the Hsp70/J-domain protein (JDP) chaperones prevents aggregation of the client protein. Here, the authors show that DnaJC7 binds preferentially to natively folded wild-type tau, via a β-turn element in tau that contains the known amyloid motif, while aggregation-prone tau mutants are reco
Spatial localisation meets biomolecular networks
1dNature Communications, Published online: 09 September 2021; doi:10.1038/s41467-021-24760-y Complex biomolecular networks are fundamental to the functioning of living systems, both at the cellular level and beyond. In this paper, the authors develop a systems framework to elucidate the interplay of networks and the spatial localisation of network components.

Måttligt med fruktklämmisar ger ingen övervikt
1dSå kallade fruktklämmisar någon gång i veckan har inget samband med övervikt hos barn. Övervikt vid 18 månaders ålder hänger i stället främst ihop med mammans BMI, visar en studie från Umeå universitet. Studien visar också att amning ger ett visst skydd mot övervikt. – Det finns ingen anledning till överdriven oro över att 1,5-åringar i Västerbotten äter fruktklämmisar så ofta att de blir övervik
