FOLDING PROJECT #17725 PROFILE

This project looks at how proteins use ion gradients to move molecules across cell membranes. These proteins are found in all living things and are important for treating diseases like cancer, diabetes, and neurological disorders. By studying these proteins, we can learn more about how they work and develop new treatments.

Projects 17711-17724 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 disease like cancer, diabetes, and neurological disorders.

These simulations will allow us to understand a universal role of ion-coupling across different families of proteins.

transporters

Proteins that move molecules across cell membranes.

Transporters are essential proteins found in all living organisms. They facilitate the movement of various substances, such as nutrients, ions, and drugs, across cell membranes. This process is crucial for numerous biological functions, including nutrient uptake, waste removal, and signal transduction. Many diseases are caused by defects in transporter function.

secondary active transporters

Transporters that use an ion gradient to move molecules across cell membranes.

Secondary active transporters are a class of membrane proteins that utilize the energy stored in an electrochemical gradient of ions to drive the transport of other molecules. They play a vital role in maintaining cellular homeostasis, nutrient uptake, and drug efflux. These transporters are often targeted by pharmaceuticals to treat various diseases.

membrane

A thin layer that surrounds cells and organelles.

The membrane is a fundamental component of all living cells. It serves as a barrier that separates the internal environment of the cell from its surroundings. The membrane is composed of lipids and proteins, which allow for selective transport of molecules in and out of the cell. It also plays a crucial role in cell signaling and communication.

proteins

Large biomolecules that perform various functions in cells.

Proteins are essential macromolecules found in all living organisms. They play a diverse range of roles, including catalyzing biochemical reactions, transporting molecules, providing structural support, and regulating cellular processes. Proteins are made up of amino acids, which are linked together in specific sequences to form polypeptide chains.

ions

Atoms or molecules that have an electrical charge.

Ions are atoms or molecules that have gained or lost electrons, resulting in a net electric charge. They play a crucial role in various cellular processes, such as nerve impulse transmission, muscle contraction, and enzyme activity. The movement of ions across cell membranes is essential for maintaining electrochemical gradients and regulating cellular function.

simulations

Computer models used to mimic real-world processes.

Simulations are computer programs that create virtual representations of real-world systems. They are widely used in various fields, including biotechnology, to study complex biological processes, design new drugs, and predict the behavior of molecules.
