RESEARCH: MEMBRANE TRANSPORT
FOLDING PROJECT #17931 PROFILE

Secondary active transporters are proteins that use ion gradients to move molecules across cell membranes. These proteins are found everywhere and are important for many bodily functions. This project uses simulations to understand how these transporters work, which could lead to new treatments for 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.

Secondary active transporters

Proteins that use ions to transport molecules across cell membranes.

Secondary active transporters are essential proteins found in all living organisms. They utilize the energy stored in an ion gradient to move other molecules across cell membranes. This process is vital for various cellular functions, including nutrient uptake, waste removal, and signal transduction. Many of these transporters are drug targets for treating diseases like cancer, diabetes, and neurological disorders.

Ion gradient

A difference in ion concentration across a cell membrane.

An ion gradient is a fundamental concept in cellular biology. It refers to the unequal distribution of ions, such as sodium (Na+) and potassium (K+), across a cell membrane. This difference in concentration creates an electrochemical potential that drives various cellular processes, including nerve impulse transmission, muscle contraction, and nutrient uptake.

Simulations

Computer models used to study biological systems.

Simulations are powerful tools used in computational biology to understand complex biological processes. Researchers create computer models that mimic the behavior of cells, molecules, or entire organisms. These simulations allow scientists to explore different scenarios, test hypotheses, and gain insights into biological phenomena.

Drug targets

Molecules or pathways that are involved in disease and can be targeted by drugs.

Drug targets are essential components of the drug discovery process. They are specific molecules or cellular pathways that play a role in the development or progression of a disease. By targeting these drug targets, researchers aim to develop therapies that can effectively treat or prevent diseases.

Cancer

A group of diseases characterized by uncontrolled cell growth.

Cancer is a complex group of diseases that involves abnormal and uncontrolled cell growth. These cells can invade surrounding tissues and spread to other parts of the body. There are many different types of cancer, each with its own unique characteristics and treatments.
