RESEARCH: CANCER
FOLDING PROJECT #17761 PROFILE

This project explores how proteins use ion power to move molecules across cell membranes. These 'secondary active transporters' are found everywhere and are important for things like fighting diseases. By studying them, we can learn about a universal rule of how these proteins work.

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 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 various molecules across cell membranes. These transporters play a crucial role in many biological processes, including nutrient uptake, waste removal, and signal transduction. Their importance makes them attractive targets for drug development to treat diseases like cancer, diabetes, and neurological disorders.

Ion gradient

A difference in ion concentration across a cell membrane.

An ion gradient is a key concept in understanding how cells maintain their internal environment and carry out essential functions. It refers to the unequal distribution of charged particles (ions) across a cell membrane. This difference in concentration creates an electrochemical potential that can be harnessed by proteins like secondary active transporters to move molecules against their concentration gradient.

Cell membrane

A thin layer that surrounds every cell.

The cell membrane is a vital structure that separates the inside of a cell from its external environment. It acts as a selective barrier, controlling the passage of molecules in and out of the cell. This regulation is essential for maintaining cellular homeostasis and allowing cells to interact with their surroundings.

Proteins

Large, complex molecules that perform a variety of functions in living organisms.

Proteins are the workhorses of cells, carrying out a vast array of tasks essential for life. They act as enzymes, catalyzing biochemical reactions; provide structural support; transport molecules; and regulate cellular processes. Their diverse functions make them crucial targets for drug development.

Drug targets

Molecules or biological pathways that are the focus of drug development.

Drug targets are specific molecules or pathways within cells that are implicated in disease processes. Identifying and targeting these pathways with drugs can help to treat or manage a variety of conditions. Drug target discovery is a crucial step in the pharmaceutical research process.

Simulations

Computer models used to mimic biological processes.

Simulations are powerful tools in biotechnology, allowing researchers to study complex biological systems in a virtual environment. They can be used to predict protein interactions, drug binding affinities, and the behavior of cells under different conditions. Simulations provide valuable insights that complement experimental research.
