RESEARCH: CANCER
FOLDING PROJECT #17749 PROFILE

This project looks at how proteins use ions to move molecules across cell membranes. These proteins are important for many things, like fighting diseases and regulating the body. By simulating these proteins, scientists hope to learn more about how they work and find new ways to treat diseases.

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

Projects 17745-17750 Molecular basis of secondary active transporters. Secondary active membrane transporters are proteins that utilize ions to transport an assortment of molecules across cell membranes.

These proteins are found in all domains in life and surprisingly, despite vastly different structures, operate under the same mechanism by using an ion gradient to assist in small molecule transport.

Furthermore, many of these secondary active transporters are drug targets to treat diseases like cancer, diabetes, and neurological disorders.

The simulations in this project will allow us to understand a universal role of ion-coupling across different families of proteins.

Secondary active transporters

Proteins that use ion gradients to transport molecules across cell membranes.

Secondary active transporters are a type of protein found in all living things. They help move molecules across cell membranes by using the energy from an ion gradient. This process is essential for many biological functions, including nutrient absorption, waste removal, and signal transduction. Because they play such important roles in health, secondary active transporters are often targeted by drugs to treat diseases like cancer, diabetes, and neurological disorders.

Ion gradient

A difference in concentration of ions across a cell membrane.

An ion gradient is a difference in the concentration of charged particles (ions) across a membrane. This difference in concentration creates an electrical potential that can be used to power cellular processes, such as transporting molecules across the membrane. Many biological processes rely on ion gradients, including nerve impulse transmission and muscle contraction.

Molecules

A group of atoms bonded together.

Molecules are the building blocks of matter. They are formed when two or more atoms bond together. Molecules can be very small, such as water (H2O), or very large, such as proteins. The properties of a molecule depend on the types of atoms it contains and how they are arranged.

Cell membranes

The outer boundary of a cell that regulates what enters and exits.

Cell membranes are the thin, flexible barriers that surround all cells. They play a vital role in protecting the cell from its environment and regulating the flow of substances in and out of the cell. Cell membranes are made up of a variety of lipids and proteins that work together to create a selectively permeable barrier.

Proteins

Large, complex molecules essential for many biological functions.

Proteins are large, complex molecules that play a wide variety of roles in living organisms. They are involved in almost every aspect of cellular function, including catalyzing reactions (enzymes), transporting molecules, providing structure, and regulating gene expression. Proteins are made up of chains of amino acids, which are linked together by peptide bonds.

Cancer

Uncontrolled growth and spread of abnormal cells.

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. These cells can invade surrounding tissues and organs, and they may also spread to other parts of the body (metastasis). Cancer is caused by a variety of factors, including genetic mutations, environmental exposures, and lifestyle choices.

Diabetes

A metabolic disorder characterized by high blood sugar levels.

Diabetes is a chronic disease that affects how the body regulates blood sugar (glucose). In people with diabetes, the body either doesn't produce enough insulin or can't use insulin effectively. Insulin is a hormone that helps cells absorb glucose from the bloodstream. Without enough insulin, glucose builds up in the blood, leading to a variety of health problems.

Neurological disorders

Conditions that affect the nervous system.

Neurological disorders are a broad category of conditions that affect the brain, spinal cord, and nerves. These disorders can cause a wide range of symptoms, including problems with movement, sensation, thinking, and emotions.
