RESEARCH: MYOSINS
FOLDING PROJECT #17441 PROFILE

This project studies myosin proteins, which are essential for muscle movement and many other bodily functions. By understanding how these proteins work, scientists hope to develop new treatments for heart diseases like cardiomyopathies and heart failure.

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 type of motor protein responsible for muscle contraction and other cellular movements.

Myosin is a crucial protein found in cells that powers movement. It's like a tiny engine within our bodies, enabling muscles to contract, allowing us to walk, run, and lift things. Myosin also plays a role in transporting materials inside cells and dividing them. Scientists are studying myosin because defects in this protein can lead to heart problems.

Proteins

Large, complex molecules made up of amino acids that are essential for the structure and function of all living things.

Proteins are the building blocks of life. They have many different jobs in our bodies, from transporting oxygen to fighting off infections. Made up of chains of smaller units called amino acids, proteins can fold into complex shapes that allow them to perform specific tasks. Scientists study proteins to understand how they work and how they can be used to treat diseases.

Cardiomyopathies

A group of diseases that affect the heart muscle.

Cardiomyopathies are a collection of conditions that weaken or stiffen the heart muscle, making it harder for the heart to pump blood. This can lead to symptoms like shortness of breath, fatigue, and irregular heartbeat. Cardiomyopathies can be caused by genetic factors, infections, or other health problems.

Heart Failure

A serious condition in which the heart cannot pump blood effectively.

Heart failure occurs when the heart muscle weakens and can't pump enough blood to meet the body's needs. This can lead to fluid buildup in the lungs, legs, and other parts of the body. Symptoms include shortness of breath, fatigue, and swelling. Heart failure is often caused by underlying conditions like coronary artery disease, high blood pressure, or diabetes.

PDB

Protein Data Bank

The Protein Data Bank (PDB) is a global repository of 3D structural data for proteins, nucleic acids, and complexes. Researchers use this information to understand how molecules work and develop new drugs.
