Design of a heterotetrameric coiled coil [PDF]
Protein Science, 2009 AbstractWe have successfully designed a simple peptide sequence that forms highly stable coiled‐coil heterotetramers. Our model system is based on the GCN4‐pLI parallel coiled‐coil tetramer, first described by Kim and coworkers (Harbury et al., Science 1993;262:1401–1407). We introduced glutamates at all of the e and c heptad positions of one sequence (

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Structural specificity in coiled-coil interactions [PDF]
Current Opinion in Structural Biology, 2008 Coiled coils have a rich history in the field of protein design and engineering. Novel structures, such as the first seven-helix coiled coil, continue to provide surprises and insights. Large-scale datasets quantifying the influence of systematic mutations on coiled-coil stability are a valuable new asset to the area.

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Self-energized plasma compressor [PDF]
, 1974 The self-energized plasma compressor is described which compresses plasma discharged from a coaxial plasma generator. The device includes a helically shaped coil which is coaxially aligned with the center axis of the coaxial plasma generator.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Magnetomotive forming for precision sizing and joining of large-diameter tubes [PDF]
, 1969 Portable electromagnetic coil enables high precision expansion or constriction and joining of large diameter metal tubes. A nonconducting mandrel or forming die is used on the side of the tubes wall opposite the coil.
