RESEARCH: MEMBRANE TRANSPORT
FOLDING PROJECT #17939 PROFILE

Secondary active transporters are proteins that use ions to move molecules across cell membranes. These transporters are found everywhere and work the same way, even though they look different. The project relates to understanding how these transporters work across many types of proteins because they're important for treating diseases like cancer and diabetes.

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.

Transporters

Proteins that move molecules across cell membranes.

Transporters are essential proteins found in cell membranes that facilitate the movement of various substances into and out of cells. They play crucial roles in numerous physiological processes, including nutrient uptake, waste removal, and signaling.

Secondary Active Transporters

Proteins that use an ion gradient to power the transport of other molecules across a membrane.

Secondary active transporters are a type of membrane protein that utilize an existing concentration gradient of ions to drive the movement of other molecules. They couple the downhill flow of ions with the uphill transport of substrates, allowing for efficient transfer against concentration gradients.

Ion Gradient

A difference in concentration of ions across a membrane.

An ion gradient refers to the unequal distribution of charged particles (ions) across a cell membrane. This concentration difference is essential for various cellular processes, including nerve impulse transmission and nutrient uptake.

Drug Targets

Molecules or pathways that are essential for disease progression and can be targeted by drugs.

Drug targets are specific molecules or cellular processes involved in the development or progression of diseases. Identifying these targets allows researchers to develop medications that can effectively inhibit or modulate their activity, leading to therapeutic benefits.

Simulations

Computer-based models used to study biological systems.

Simulations are computer programs that mimic the behavior of complex biological systems. They allow researchers to explore various scenarios and test hypotheses without conducting real-world experiments.
