FOLDING PROJECT #17788 PROFILE

Secondary active transporters are proteins that use ion gradients to move molecules across cell membranes. They're found everywhere and help transport many things, including drugs. The project uses simulations to understand how these transporters work in different types of proteins.

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.

secondary active transporters

Proteins that use ion gradients to move molecules across cell membranes.

Secondary active transporters are essential proteins found in all living organisms. They help move various molecules across cell membranes by utilizing the energy stored in an existing ion gradient. This process is crucial for many cellular functions, including nutrient uptake, waste removal, and signal transduction. Disruptions in these transporters can lead to various diseases, making them important drug targets.

membrane transporters

Proteins that facilitate the movement of substances across cell membranes.

Membrane transporters are specialized proteins embedded within cell membranes. They play a vital role in regulating the flow of molecules into and out of cells, ensuring proper cellular function. Different types of transporters move specific molecules, such as nutrients, ions, or waste products, through various mechanisms.

ion gradient

A difference in ion concentration across a membrane.

An ion gradient refers to an uneven distribution of charged ions (like sodium or potassium) across a cell membrane. This concentration difference creates a potential energy that can be harnessed for various cellular processes. For example, nerve cells utilize ion gradients to transmit electrical signals.

drug targets

Molecules or pathways that are targeted by drugs to treat diseases.

Drug targets are specific molecules or biological pathways involved in disease development. By targeting these molecules, drugs can either inhibit their function (for example, blocking a harmful enzyme) or enhance their activity (for example, stimulating a beneficial protein). Identifying effective drug targets is crucial for developing new therapies.

simulations

Computer models used to study biological systems.

Simulations are powerful tools used in computational biology to model and analyze complex biological processes. By creating virtual representations of cells, molecules, or entire organisms, researchers can investigate how these systems behave under different conditions. Simulations can help accelerate drug discovery by predicting the effects of potential drugs on target molecules.
