Low-resolution skeletal channel structure extends excitation-contraction models; leaves open cardiac isoform relevance or therapeutic translation.
The study provides a 30-A resolution 3D structure of the skeletal muscle voltage-gated L-type Ca2+ channel, offering insights into its physical coupling with the ryanodine receptor during excitation-contraction coupling.
Serysheva et al. (2002) studied this question. Electron cryomicroscopy revealed the 30-Å resolution 3D structure of the skeletal muscle voltage-gated L-type Ca2+ channel, showing an asymmetrical heart- and handle-shaped architecture.
