    Observation of long-range tertiary interactions during ligand binding by the TPP riboswitch aptamer

    Van K Duesterberg et al.
    The combined use of optical trapping and single-molecule FRET permits the study of riboswitch structure formation and conformational dynamics at the same time.

    Retrograde ERK activation waves drive base-to-apex multicellular flow in murine cochlear duct morphogenesis

    Mamoru Ishii et al.
    Live-cell imaging and mathematical modeling reveal the physical basis of collective cell migration underlying spiral cochlear duct formation during murine inner ear development.

    XLF acts as a flexible connector during non-homologous end joining

    Sean M Carney et al.
    The disordered C-terminal tail allows XRCC4-like factor (XLF) to find and bind the XRCC4-Lig4 complex, enabling DNA end synapsis and subsequent ligation during non-homologous end joining.

    FRET kinase sensor development reveals SnRK2/OST1 activation by ABA but not by MeJA and high CO2 during stomatal closure

    Li Zhang et al.
    Development of a real-time SnRK2 kinase FRET reporter reveals rapid SnRK2 activation by ABA, but not by Methyl-Jasmonate or elevated CO2, while directly demonstrating basal SnRK2 activity in guard cells.

    Monitoring site-specific conformational changes in real-time reveals a misfolding mechanism of the prion protein

    Ishita Sengupta, Jayant Udgaonkar
    Multi-site FRET measurements of moPrP oligomerization at low pH indicate that major conformational changes take place as monomers reversibly transform into large oligomers, which subsequently disassemble reversibly into small oligomers.

    In vitro FRET analysis of IRE1 and BiP association and dissociation upon endoplasmic reticulum stress

    Megan C Kopp et al.
    Quantitative FRET UPR induction assay is used to measure IRE1 and BIP association and dissociation by a variety of ER misfolded proteins and by an important BiP substrate-binding domain mutant, significantly enhancing the evidence for the allosteric UPR induction model.

    A FRET-based study reveals site-specific regulation of spindle position checkpoint proteins at yeast centrosomes

    Yuliya Gryaznova et al.
    Daughter-cell-associated factors and centrosome-based regulation is important in mitotic exit and spindle position checkpoint control.

    Hexameric helicase G40P unwinds DNA in single base pair steps

    Michael Schlierf et al.
    Single-molecule FRET experiments reveal that G40P, a DnaB-like helicase, unwinds double-stranded DNA in single base pair steps and its processivity is enhanced by host primase DnaG.

    A Gs-coupled purinergic receptor boosts Ca2+ influx and vascular contractility during diabetic hyperglycemia

    Maria Paz Prada et al.
    A multi-pronged approach shows that a Gs-coupled purinergic receptor is a sensor for glucose-mediated, PKA-dependent potentiation of vascular L-type calcium channels and vasoconstriction.
