RESEARCH: SIGNALING PROTEIN
FOLDING PROJECT #19232 PROFILE

The project relates to how tiny changes in signaling proteins (like a letter swap in their code) can cause BIG problems with cell communication. These errors are linked to diseases like diabetes and cancer, and understanding them helps us develop new medicines.

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

The impact of point-mutations on signaling proteins Mutations in proteins are often found to have dramatic functional consequences through changes in conformational dynamics, ligand binding, and association with signaling partners.

These changes sometimes lead to pathological outcomes as signal transduction problems are involved in diabetes, heart disease, and many cancers.

Additionally, proteins involved in cell signaling are the target of over half of approved drugs.

This project aims to understand how a small number of point-mutants in signaling proteins can cause a dramatic change in how they modulate cell signaling pathways.

Point-mutations

Permanent alterations in a DNA sequence at a single nucleotide.

Point-mutations are small changes to the DNA sequence that make up genes. These changes can affect how a gene is read and translated into a protein, sometimes leading to altered protein function.

---

Signaling proteins

Proteins that transmit signals within and between cells.

Signaling proteins are crucial for communication within and between cells. They receive, process, and transmit information in the form of chemical signals, regulating various cellular processes like growth, differentiation, and response to stimuli.

---

Conformational dynamics

The changes in shape of a molecule over time.

Conformational dynamics refer to the constant movement and flexibility of molecules like proteins. These changes in shape are essential for their function, allowing them to bind to other molecules and carry out their roles.

---

Ligand binding

The process of a molecule (ligand) attaching to a specific receptor site on another molecule.

Ligand binding is the key to many biological processes. It involves a specific molecule, called a ligand, attaching to a target molecule, often a protein, at a designated site. This interaction can trigger various cellular responses.

---

Signal transduction

The process of transmitting signals within and between cells.

Signal transduction is the intricate communication network within living organisms. It involves a series of steps where signals are received, processed, and relayed through different molecules, ultimately leading to specific cellular responses.

---

Diabetes

A metabolic disorder characterized by high blood sugar levels.

Diabetes is a chronic condition where the body struggles to regulate blood sugar levels. This can lead to various complications affecting different organs and systems.

---

Heart disease

A broad term encompassing various conditions affecting the heart.

Heart disease refers to a range of conditions impacting the structure and function of the heart. This can include coronary artery disease, heart failure, and arrhythmias.

---

Cancers

Uncontrolled growth and spread of abnormal cells.

Cancers are a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. This can lead to tumor formation and damage to surrounding tissues and organs.

---

Drugs

Substances used to treat, prevent, or diagnose diseases.

Drugs are chemical compounds designed to interact with biological systems to produce specific effects. They can be used to treat a wide range of conditions, from infections to chronic diseases.
