    Dynamics at the serine loop underlie differential affinity of cryptochromes for CLOCK:BMAL1 to control circadian timing

    Jennifer L Fribourgh, Ashutosh Srivastava ... Carrie L Partch
    The affinity of circadian repressors CRY1 and CRY2 for their cognate transcription factor CLOCK:BMAL1 is regulated by differential dynamics at the serine loop and interactions with the PER2 corepressor.

    Guanidine hydrochloride reactivates an ancient septin hetero-oligomer assembly pathway in budding yeast

    Courtney R Johnson, Marc G Steingesser ... Michael A McMurray
    A naturally-occurring small molecule acts as a chemical chaperone in vivo to alter the folding of a budding yeast septin and promote an oligomerization pathway that was lost during evolution.

    Distinct inactive conformations of the dopamine D2 and D3 receptors correspond to different extents of inverse agonism

    J Robert Lane, Ara M Abramyan ... Lei Shi
    The occupation of a sub-pocket near the Na+-binding site in D2R by the Na+-insensitive antagonists is the structural basis for their greater inverse agonism than that of the Na+-sensitive ligands.

    New approach for membrane protein reconstitution into peptidiscs and basis for their adaptability to different proteins

    Gabriella Angiulli, Harveer Singh Dhupar ... Thomas Walz
    Cryo-EM structures reveal how the peptidisc scaffold can adapt to different membrane proteins, establishing it as a universal membrane mimetic to stabilize membrane proteins in solution.

    Regulation of mRNA translation by a photoriboswitch

    Kelly A Rotstan, Michael M Abdelsayed ... Andrej Luptak
    A synthetic riboswitch binding one isoform of a photoreversible ligand provides a photoregulatory tool for bacterial translation initiation.

    A tryparedoxin-coupled biosensor reveals a mitochondrial trypanothione metabolism in trypanosomes

    Samantha Ebersoll, Marta Bogacz ... R Luise Krauth-Siegel
    African trypanosomes have a trypanothione-based mitochondrial thiol redox metabolism.

    Misfolded proteins bind and activate death receptor 5 to trigger apoptosis during unresolved endoplasmic reticulum stress

    Mable Lam, Scot A Marsters ... Peter Walter
    Death receptor 5 can directly sense misfolded proteins downstream of the endoplasmic reticulum to provide a quality control mechanism that executes apoptosis and prevents further production of misfolded proteins.

    A native prokaryotic voltage-dependent calcium channel with a novel selectivity filter sequence

    Takushi Shimomura, Yoshiki Yonekawa ... Katsumasa Irie
    The small glycine residue in the Cav selectivity filter is an overlooked feature that determines Ca2+ selectivity and provides new insight into the Ca2+ selectivity mechanism conserved from prokaryotes to eukaryotes.
