RESEARCH: CANCER
FOLDING PROJECT #17785 PROFILE

This project looks at how proteins use ion power to move molecules across cell membranes. These proteins are super important because they're found everywhere and help with things like fighting diseases. The simulations will help us understand how these proteins work no matter their shape or size.

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.

Transporters

Proteins that move molecules across cell membranes.

Transporters are essential proteins that facilitate the movement of various molecules across cell membranes. They play a crucial role in maintaining cellular homeostasis and transporting nutrients, ions, and waste products. Different types of transporters exist, including primary and secondary active transporters, as well as passive transporters.

Secondary Active Transporters

Membrane proteins that use an ion gradient to transport molecules across the membrane.

Secondary active transporters are a type of protein embedded in cell membranes. They leverage the energy stored in an ion gradient (a difference in concentration of charged particles) to move other molecules against their concentration gradient – essentially uphill. This process is crucial for nutrient uptake, waste removal, and maintaining cellular balance.

Ion Gradient

A difference in concentration of ions across a membrane.

An ion gradient is the uneven distribution of charged particles (ions) across a cell membrane. This imbalance creates an electrochemical potential that can be used to drive various cellular processes, such as the movement of molecules through secondary active transporters.

Membrane Proteins

Proteins embedded in cell membranes.

Membrane proteins are specialized proteins that reside within the lipid bilayer of cell membranes. They perform a wide range of functions, including transporting molecules, receiving signals from the environment, and anchoring the membrane to the cytoskeleton.
