Three-dimensional structure of the basketweave Z-band in midshipman fish sonic muscle.
(NATL ACAD SCIENCES, 2019-07-30)
Striated muscle enables movement in all animals by the contraction of myriads of sarcomeres joined end to end by the Z-bands. The contraction is due to tension generated in each sarcomere between overlapping arrays of actin ...
The Interacting Head Motif Structure Does Not Explain the X-Ray Diffraction Patterns in Relaxed Vertebrate (Bony Fish) Skeletal Muscle and Insect (Lethocerus) Flight Muscle.
(MDPI, 2019-09-14)
Unlike electron microscopy, which can achieve very high resolution but to date can only be used to study static structures, time-resolved X-ray diffraction from contracting muscles can, in principle, be used to follow the ...
Structural basis of Cullin 2 RING E3 ligase regulation by the COP9 signalosome.
(NATURE RESEARCH, 2019-08-23)
Cullin-Ring E3 Ligases (CRLs) regulate a multitude of cellular pathways through specific substrate receptors. The COP9 signalosome (CSN) deactivates CRLs by removing NEDD8 from activated Cullins. Here we present structures ...
