Another possibility is that the differences in function of myosin IIA and myosin IIB reflect differences in their basic motor properties. Although myosin IIA and myosin IIB share many biochemical ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

At the molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. New electron cryomicroscopy images with unprecedented resolution taken by researchers at Osaka ...

Researchers at the University of Cincinnati say a regulatory protein found in skeletal muscle fiber may play an important role in the body's fight or flight response when encountering stressful ...

A visualization made from nearly 100,000 electron microscope images has revealed the ingenious way a protein involved in muscle activity shuts itself down to conserve energy. The protein is called ...

In its early stages, Alzheimer disease is increasingly recognized as a disease of synapses, those key mediators of memory storage in the brain. Enhancing synaptic function, therefore, might be a ...

Biomolecular condensates are distinct molecular communities made of DNA, RNA and proteins that “condense” molecules to key locations inside cells. Intense efforts have focused on uncovering the ...

"This process appears to be regulated by myosin-binding protein-C (cMyBP-C), which is a heart muscle protein," study author Kerry McDonald said. "Our study investigated its role in cardiac muscle ...
