RESEARCH: MYOSINS
FOLDING PROJECT #18309 PROFILE

This project studies different types of myosins found in the human body. Myosins are proteins that power our movements, from muscle contractions to moving things inside cells. The project looks at how fast and strong each type is, which can help understand diseases like heart problems and Usher syndrome. By learning more about myosins, scientists hope to develop better treatments without harmful side effects.

Note: This TLDR is a simplication and may not be 100% accurate.

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.

Although structurally similar, myosins actually differ substantially in their properties and distribution in the body.

This project is studying those differences, especially the differences in speed and power.

We are interested in how this might help us understand diseases that result from defects in myosin, including Usher syndrome and, especially, hypertrophic and dilated cardiomyopathies.

We are using this information to understand and design specific theraputics that don't have off-target effects.

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

Myosins

Proteins responsible for force generation in the body.

Myosins are a family of proteins that play a crucial role in various cellular functions, particularly muscle contraction and intracellular transport. They convert chemical energy into mechanical work, enabling movement at both the cellular and organismal level. Defects in myosin function can lead to a range of diseases, including cardiomyopathies and Usher syndrome.

Hypertrophic Cardiomyopathy

A disease characterized by thickening of the heart muscle.

Hypertrophic cardiomyopathy is a genetic disorder that causes the heart muscle to become abnormally thick. This thickening can obstruct blood flow from the heart, leading to shortness of breath, chest pain, and an increased risk of sudden cardiac arrest.

---

Dilated Cardiomyopathy

A disease characterized by enlargement and weakening of the heart muscle.

Dilated cardiomyopathy is a condition where the heart chambers enlarge and become too weak to pump blood effectively. This can lead to fatigue, shortness of breath, fluid retention, and heart failure.

Usher Syndrome

A genetic disorder characterized by hearing loss and vision impairment.

Usher syndrome is a group of inherited disorders that cause both hearing loss and vision problems. It affects people of all ages and can range in severity from mild to profound.

Theraputics

Medications or treatments used to prevent or cure diseases.

Therapies encompass a wide range of interventions aimed at treating and managing diseases. These can include medications, surgery, physical therapy, radiation therapy, and lifestyle modifications.

PDB

Protein Data Bank

The Protein Data Bank (PDB) is a global repository of 3-dimensional structural data of biological macromolecules, primarily proteins and nucleic acids. This database is essential for understanding the structure and function of these molecules and for drug discovery.

Molecule of the Month

A monthly feature highlighting a specific protein structure.

The 'Molecule of the Month' is a recurring program by the Protein Data Bank that showcases a unique protein structure and its significance in biological research. It aims to raise awareness about the importance of structural biology and inspire further exploration.
