RESEARCH: MYOSINS
FOLDING PROJECT #17443 PROFILE

This project looks at myosins, the proteins that power most body movements. Scientists want to understand how drugs could fix problems with myosins that cause heart diseases like cardiomyopathies and heart failure. Myosins are super important for everything from muscle contractions to moving stuff around inside our cells!

This project simulates several myosins found in the human body.

Myosins are the proteins responsible for most of the force generated by the body, from the contraction of muscles to the movement of materials around the cell.

We are interested in understanding the mechanistic basis of drugs that might be used to treat defects in myosin, including hypertrophic and dilated cardiomyopathies as well as heart failure.

Myosin was featured as the PDB Molecule of the Month in June 2001.

myosin

A motor protein that converts chemical energy into mechanical work.

Myosins are a family of proteins crucial for muscle contraction and cellular movement. They function by binding to actin filaments and using ATP as fuel to generate force. Defects in myosin can lead to various diseases, including cardiomyopathies and heart failure. Understanding the mechanics of myosin is essential for developing targeted therapies.

proteins

Large biomolecules composed of amino acids.

Proteins are the building blocks of life, responsible for a wide range of functions within cells and organisms. They play essential roles in metabolism, structure, signaling, and defense. Understanding protein structure and function is crucial for advancements in medicine, agriculture, and biotechnology.

muscle contraction

The process by which muscle fibers shorten and generate force.

Muscle contraction is a complex physiological process involving the interaction of proteins like actin and myosin. It allows for movement, posture maintenance, and other essential bodily functions. Understanding muscle contraction mechanisms is crucial for treating muscle disorders and developing new therapies.

cardiomyopathy

A disease of the heart muscle that impairs its ability to pump blood effectively.

Cardiomyopathy refers to a group of diseases affecting the heart muscle. It can cause various symptoms like fatigue, shortness of breath, and irregular heartbeat. Different types of cardiomyopathy exist, each with unique causes and treatments. Research focuses on understanding the underlying mechanisms and developing effective therapies.

heart failure

A chronic condition where the heart cannot pump blood effectively enough to meet the body's needs.

Heart failure occurs when the heart muscle weakens or becomes stiff, leading to an inability to pump adequate blood. This can result in fluid buildup in the lungs and other organs, causing symptoms like fatigue, shortness of breath, and swelling. Treatment options include medications, lifestyle changes, and sometimes surgery.
