RESEARCH: MEMBRANE TRANSPORT
FOLDING PROJECT #17940 PROFILE

Secondary active transporters are proteins that use ion power to move molecules across cell membranes. These transporters are found everywhere in nature and are important for health. The project relates to using computer simulations to understand how these transporters work, which could lead to new treatments for diseases.

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

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.

Molecular basis

The fundamental structure and function of molecules.

This refers to the underlying molecular mechanisms that drive the activity and behavior of secondary active transporters. It explores how these proteins are structured at a molecular level and how their components interact to facilitate transport.

Secondary active transporters

Membrane proteins that use an ion gradient to drive the transport of other molecules across a cell membrane.

These are specialized proteins embedded in cell membranes. They harness the energy stored in an electrochemical gradient of ions (like sodium or potassium) to move other molecules against their concentration gradient, from an area of low concentration to an area of high concentration. This is essential for various cellular processes.

Ion gradient

A difference in ion concentration across a membrane.

This refers to the unequal distribution of charged particles (ions) across a cell membrane. Typically, there is a higher concentration of specific ions outside the cell compared to inside, creating an electrochemical potential that can be harnessed for energy.

Cell membranes

Phospholipid bilayers that surround cells and control the movement of substances in and out.

These are thin, flexible barriers that enclose all living cells. They are made up of a double layer of phospholipids, with embedded proteins. Cell membranes regulate what enters and exits the cell, maintaining its internal environment.

Proteins

Large biomolecules made up of amino acids.

Proteins are the workhorses of the cell, responsible for a wide range of functions. They can act as enzymes, structural components, signaling molecules, and more. Their complex shapes and arrangements allow them to perform specific tasks essential for life.

---

Drug targets

Molecules or cellular pathways involved in disease processes that can be inhibited by drugs.

These are specific molecules or biological pathways that play a key role in the development or progression of diseases. By targeting these drug targets with medications, scientists aim to disrupt the underlying disease mechanisms and alleviate symptoms.

Cancer

Uncontrolled cell growth and spread.

Cancer is a broad term for a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. These cells can invade surrounding tissues and spread to other parts of the body.

---

Diabetes

Metabolic disorder characterized by high blood sugar levels.

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

Neurological disorders

Conditions that affect the nervous system.

Neurological disorders encompass a wide range of conditions that impact the brain, spinal cord, and nerves. These can include diseases like Alzheimer's, Parkinson's, multiple sclerosis, stroke, and epilepsy.
