RESEARCH: MEMBRANE TRANSPORT
FOLDING PROJECT #17946 PROFILE

Secondary active transporters are proteins that use ion gradients to move molecules across cell membranes. They're found everywhere in life and work similarly despite different structures. This project uses simulations to understand how these transporters, important for treating diseases like cancer and diabetes, operate universally.

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 interactions of molecules that determine their function.

Molecular basis refers to the underlying structure and interactions of molecules, particularly at the atomic level. Understanding a molecule's molecular basis helps explain its properties and how it functions within biological systems.

Transporters

Membrane proteins that facilitate the movement of molecules across cell membranes.

Transporters are essential proteins embedded within cell membranes. They act like gateways, selectively allowing specific molecules to enter or exit the cell. This transport process is crucial for various cellular functions, including nutrient uptake, waste removal, and signal transduction.

Secondary active transporters

A type of membrane transporter that uses the energy stored in an ion gradient to drive the transport of another molecule against its concentration gradient.

Secondary active transporters are a specialized group of proteins involved in moving molecules across cell membranes. They leverage the electrochemical gradient created by ions (like sodium or potassium) to power the transport of other substances, often against their natural concentration gradient. This process is essential for maintaining cellular homeostasis and regulating various physiological functions.

Ion gradient

A difference in ion concentration across a cell membrane.

An ion gradient refers to the unequal distribution of electrically charged ions (like sodium, potassium, or calcium) on either side of a cell membrane. This gradient plays a crucial role in various cellular processes, including nerve impulse transmission, muscle contraction, and nutrient uptake. It is maintained by specialized transport proteins that actively move ions across the membrane.

Drug targets

Molecules or biological pathways that are potential targets for drug therapies.

Drug targets are specific molecules or cellular processes that are involved in the development or progression of diseases. By targeting these specific pathways with drugs, researchers aim to inhibit or modulate their activity and achieve therapeutic effects. Common drug targets include proteins, enzymes, receptors, and genes.
