SIBYLS has installed new robotics that halve the time it takes to collect a full 96-well plate, from approximately 5 hours to 2.5 hours per plate (with the potential to collect a plate in 10 minutes over the coming year). We believe this will be a game changer for many reasons. We will be able…

In this paper, the authors show that CRY1, a protein coding gene that activates circadian gene expression and metabolic states and circadian oscillators, binds directly to the PAS domain core of CLOCK:BMAL1. Precise control of CLOCK:BMAL1 activity by coactivators and repressors establishes the ~24 hr periodicity of gene expression. Integrative modeling and solution X-ray scattering…

Apoptosis-inducing factor (AIF) is critical for mitochondrial respiratory complex biogenesis and for mediating necroptotic parthanatos; these functions are seemingly regulated by enigmatic allosteric switching driven by NADH charge-transfer complex (CTC) formation. In this paper the authors define molecular pathways linking AIF’s active site to allosteric switching regions by characterizing dimer-permissive mutants using small-angle X-ray scattering…

Tip link filaments convey force and gate inner-ear hair-cell transduction channels to mediate perception of sound and head movements. Cadherin-23 and protocadherin-15 form tip links through a calcium-dependent interaction of their extracellular domains made of multiple extracellular cadherin (EC) repeats. These repeats are structurally similar, but not identical in sequence, often featuring linkers with conserved…

The facilities and staff at the SYBILS beamline contributed to this breakthrough study exploring the extent to which naturally occurring proteins sample the space of folded structures accessible to the polypeptide chain. Naturally occurring proteins–chains of amino acids that fold into functional, three-dimensional shapes–are believed to represent just a small fraction of the universe of…
