RESEARCH: SIGNALING PROTEIN
FOLDING PROJECT #19233 PROFILE

The project relates to how tiny changes (point mutations) in proteins that send signals inside cells can have big effects on how our bodies work. These changes can cause diseases like diabetes and cancer, but also help make medicines that target these proteins.

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

Changes in a DNA sequence involving one or a few nucleotides.

Point-mutations are alterations in the DNA sequence at a single location. These changes can affect how genes are expressed and lead to variations in protein structure and function. Understanding point-mutations is crucial in fields like medicine and genetics, as they can contribute to diseases and influence drug development.

signaling proteins

Proteins that transmit signals within and between cells.

Signaling proteins play a vital role in cell communication. They receive signals from the environment or other cells and relay them through complex pathways, ultimately leading to changes in cellular behavior. These changes can range from growth and division to specialized functions like immune responses.

---

conformational dynamics

The changes in shape of a molecule over time.

Conformational dynamics describe how molecules, especially proteins, constantly shift and change their shape. These movements are crucial for many biological processes, including protein function, interactions with other molecules, and response to environmental cues.

---

ligand binding

The interaction between a molecule (ligand) and a receptor protein.

Ligand binding is a fundamental process in cell signaling. A ligand, often a small molecule or hormone, attaches to a specific receptor protein on the cell surface or inside the cell. This interaction triggers a cascade of events that ultimately leads to a cellular response.

---

signal transduction

The process of transmitting signals within and between cells.

Signal transduction is the intricate network of pathways that allows cells to receive, process, and respond to signals from their environment. This communication system is essential for coordinating cellular activities, regulating growth and development, and maintaining homeostasis.

---

diabetes

A metabolic disorder characterized by high blood sugar levels.

Diabetes is a chronic condition that affects how the body regulates blood sugar (glucose). The pancreas doesn't produce enough insulin or the body can't effectively use the insulin it produces. This leads to elevated blood sugar, which can damage various organs over time.

---

heart disease

A range of conditions affecting the heart.

Heart disease encompasses various disorders that impact the heart's structure and function. It includes conditions like coronary artery disease, heart failure, arrhythmias, and congenital heart defects. Heart disease is a leading cause of death worldwide.

---

cancers

Uncontrolled growth and spread of abnormal cells.

Cancers are a group of diseases characterized by the uncontrolled proliferation and spread of abnormal cells. They can arise in various tissues and organs, leading to tumors that can invade surrounding tissues and metastasize to distant sites.

---

drugs

Substances used to treat or prevent disease.

Drugs are chemical substances designed to exert specific effects on the body. They can be used to treat a wide range of conditions, from infections and inflammation to chronic diseases like diabetes and cancer. Drug development is a complex process involving extensive research and testing.
