Using technologies like electron microscopy (EM) it is possible to capture molecular mechanisms in great detail, but not when these mechanisms are currently moving. The field of cryomicroscopy ...

Understanding how microscopic interactions between proteins in cells produce large-scale organization and asymmetry is a fundamental question in cell biology.

The novel cardiac myosin inhibitor aficamten improved peak oxygen uptake in symptomatic obstructive hypertrophic cardiomyopathy (HCM), the pivotal SEQUOIA-HCM trial showed. At 24 weeks, the mean ...

The experimental image shows two proteins -- myosin (cyan) and actin (red) -- in a chick embryo during gastrulation, highlighting the main body axes and the dominant force-generating regions (cyan).

A human heart might contract some three billion times over a lifetime, and each one of those contractions is driven by a protein called myosin. One of three classes of so-called motor proteins in our ...

Hierarchical structure of muscle and activation of thin filaments. In both skeletal and cardiac muscles under a relaxed state, a low intracellular calcium ion concentration is maintained and the ...
