RESEARCH: MYOSINS
FOLDING PROJECT #17409 PROFILE

This project looks at myosin proteins, which power most body movements like muscle contractions and cell processes. Understanding how drugs affect myosin could help treat heart problems like cardiomyopathies and heart failure. Myosin is so important it was even named Molecule of the Month by experts!

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.

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.

myosins

Proteins responsible for force generation in the body.

Myosins are a family of motor proteins essential for various cellular processes. They convert chemical energy into mechanical work, enabling muscle contraction, intracellular transport, and cell division. Defects in myosin function can lead to several diseases, including cardiomyopathies and heart failure.

proteins

Large biomolecules essential for structure and function in living organisms.

Proteins are complex molecules made up of amino acids. They perform a wide range of functions in cells, including catalyzing reactions, transporting molecules, providing structural support, and regulating cellular processes. Proteins are crucial for all aspects of life.

muscle

Tissue responsible for movement and force generation.

Muscle tissue is specialized for contraction, allowing for movement, posture maintenance, and heat generation. There are three types of muscle: skeletal (voluntary), smooth (involuntary), and cardiac (heart). Muscle contractions are powered by the interaction between proteins called actin and myosin.

cell

Fundamental unit of life.

Cells are the basic building blocks of all living organisms. They are enclosed by a membrane and contain genetic material (DNA), ribosomes for protein synthesis, and various organelles that carry out specific functions. Cells can replicate independently and perform essential tasks like metabolism, growth, and response to stimuli.

drug

A substance used to treat or prevent disease.

Drugs are chemical compounds that interact with biological systems to produce a desired effect. They can be used to treat a wide range of conditions, from infections to chronic diseases. Drugs are developed and tested through rigorous clinical trials to ensure their safety and efficacy.

cardiomyopathy

Disease of the heart muscle.

Cardiomyopathy is a group of diseases that affect the heart muscle, making it harder for the heart to pump blood effectively. This can lead to symptoms such as shortness of breath, fatigue, and swelling in the legs and ankles. Cardiomyopathies can have various causes, including genetics, infections, and lifestyle factors.

---

heart failure

Inability of the heart to pump blood effectively.

Heart failure occurs when the heart muscle weakens and cannot pump enough blood to meet the body's needs. This can lead to a buildup of fluid in the lungs and other parts of the body, causing symptoms such as shortness of breath, fatigue, and swelling. Heart failure is a serious condition that often requires medical treatment.
