Muscles contract thanks to the work of a protein called myosin. Using energy from adenosine triphosphate, this molecular motor works with fibrils of the protein actin to drive muscle contraction.

From the first nerve signal to the final movement, your muscles rely on a complex chain of events involving nerves, proteins, and energy. Actin and myosin filaments slide past each other to create ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

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 ...

Research has uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the ...

Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response ...

Most of us will probably be able to recall at least vaguely that a molecule called ATP is essential for making our bodies move, but this molecule is only a small part of a much larger system. Although ...

The Moore lab investigates how proteins build contractile systems that power cells and whole organisms. Collaboratively, we connect molecular mechanisms to tissue-level performance using ...

Our skin and mucous membranes are protected by epithelial cells. This barrier tissue performs its function thanks to specialized structures called junctions. They ensure cell cohesion and regulate ...
