RESEARCH: MYOSINS
FOLDING PROJECT #18310 PROFILE

This project studies different types of myosin proteins found in the body. Myosins are responsible for muscle contractions and movement inside cells. The project focuses on how fast and strong each myosin type is, which could help us understand diseases like heart conditions caused by faulty myosins. This research can also lead to new treatments that specifically target these diseases.

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.

Myosin

A family of motor proteins responsible for force generation.

Myosins are essential proteins that power many cellular functions. They work like tiny motors, using energy to move along cellular structures. This movement is crucial for muscle contraction, cell division, and transporting materials within cells. Defects in myosin can lead to various diseases, including muscular dystrophies and heart conditions.

Muscle

A tissue composed of cells that can contract to produce movement.

Muscles are tissues specialized for contraction, allowing us to move. There are three types: skeletal (for voluntary movements), smooth (for involuntary movements in organs), and cardiac (found only in the heart). Muscle contractions involve complex interactions between proteins like actin and myosin.

Protein

A large biomolecule composed of chains of amino acids.

Proteins are the workhorses of cells, performing a vast array of functions. They act as enzymes (catalyzing reactions), structural components (providing shape and support), transporters (moving molecules across membranes), and signaling molecules (transmitting information).

---

Cell

The basic unit of life.

Cells are the fundamental building blocks of all living organisms. They carry out essential functions like metabolism (converting energy), growth, and reproduction. Different types of cells have specialized structures and functions, working together to form tissues and organs.

---

Disease

A condition that impairs normal bodily functions.

Diseases are disruptions in the body's normal processes, leading to symptoms and dysfunction. They can be caused by various factors like infections, genetic abnormalities, environmental exposures, or lifestyle choices.

---

Therapy

Treatment intended to alleviate or cure a disease.

Therapies are interventions designed to address and manage diseases. They can include medications, surgery, radiation therapy, lifestyle changes, or a combination of approaches.

---

Cardiac

Relating to the heart.

Cardiac refers to anything related to the heart and its function. Cardiology is the branch of medicine that specializes in diagnosing and treating heart conditions.

---

Usher syndrome

A rare genetic disorder that causes hearing loss and vision impairment.

Usher syndrome is a group of inherited disorders characterized by both vision and hearing problems. It affects various genes involved in the development of sensory organs.

PDB

Protein Data Bank.

The Protein Data Bank (PDB) is a global repository of 3D structural data for biological macromolecules. It provides researchers with valuable information about protein shapes and functions.
