While their functions are diverse, myosins are similar in structure. NMII is so much like cardiac myosin, which keeps the ...

The human body contains three kinds of muscle tissue: skeletal, smooth, and cardiac. Only cardiac muscle tissue, comprising cells called myocytes, is present in the heart.

In healthy muscle, small threadlike components called actin and myosin neatly line up next to each other. With DOMs, “all of the actin and myosin are jumbled together,” Dr. Reiner says.

This article describes the structure of the actin motor protein, myosin, and its utilization in normal cellular processes.

The cells produce specific proteins—actin and myosin—that cause muscles to contract and relax like rubber bands at different speeds.

Myosin light chain (MLC) phosphorylation is the essential determinant of smooth muscle contraction because it increases cross-bridge cycling. MLC phosphorylation state is the result of a ...

An effective myosin purification approach was originally developed for chicken gizzard smooth muscle myosin. More recently, we successfully adapted the procedure to bovine tracheal smooth muscle. This ...

Does protein build muscle? The answer to this question is a resounding, ‘yes’. Muscle tissue is composed of a repeating structure of two protein filaments: myosin and actin. Myosin and actin ...

To understand what causes muscle fatigue, it’s worth looking at what exactly muscle fatigue is. If you exercise regularly, you may be familiar with the sensation of a dull ache in your muscles ...
