RESEARCH: CANCER
FOLDING PROJECT #17765 PROFILE

This project studies how proteins use ion power to move molecules across cell membranes. These proteins are super important because they're involved in many diseases and some even make good drug targets. By studying them, we can learn how different types of these proteins work together.

Projects 17745-17750 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 crucial proteins found in all living organisms. They work by using the energy from an existing ion gradient to move other molecules across cell membranes. This process is essential for various biological functions, including nutrient uptake, waste removal, and signal transduction. Many secondary active transporters are targets for drugs used to treat diseases such as cancer, diabetes, and neurological disorders.

Ion gradient

A difference in ion concentration across a membrane.

An ion gradient is the unequal distribution of ions on either side of a cell membrane. This difference in concentration creates an electrical potential, which can be used by cells to power various processes, such as nerve impulse transmission and muscle contraction. Secondary active transporters utilize these ion gradients to drive the transport of other molecules across the membrane.

Drug targets

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

Drug targets are specific molecules or proteins involved in disease pathways. By targeting these molecules, drugs can interfere with the disease process and alleviate symptoms. Secondary active transporters are often drug targets because they play crucial roles in various physiological processes, including nutrient uptake and signal transduction.

Simulations

Computer-based models that mimic real-world processes.

Simulations are powerful tools used in various scientific fields to study complex systems. In biotechnology, simulations can be used to model biological processes, such as protein folding and drug interactions. These simulations can provide valuable insights into the mechanisms underlying disease and guide the development of new treatments.

Proteins

Large biomolecules essential for various cellular functions.

Proteins are complex molecules composed of amino acids. They play a wide range of roles in living organisms, including catalyzing biochemical reactions, transporting molecules, providing structural support, and regulating cellular processes. Understanding the structure and function of proteins is crucial for advancements in biotechnology and medicine.
