RESEARCH: CANCER
FOLDING PROJECT #17728 PROFILE

This project looks at how special proteins use energy from ions to move molecules across cell membranes. These proteins are found everywhere and are important for things like fighting cancer, diabetes, and brain disorders. By studying them, we can learn more about how cells work and how to develop new medicines.

Projects 17711-17724 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 disease like cancer, diabetes, and neurological disorders.

These simulations will allow us to understand a universal role of ion-coupling across different families of proteins.

secondary active transporter

A protein that uses an ion gradient to transport molecules across cell membranes.

Secondary active transporters are crucial proteins found in all living organisms. They utilize the energy stored in an ion gradient to move various molecules across cell membranes. This process is essential for numerous cellular functions, including nutrient uptake, waste removal, and signal transduction. These transporters are often targets for drugs used to treat diseases like cancer, diabetes, and neurological disorders.

ion gradient

A difference in concentration of ions across a membrane.

An ion gradient is the uneven distribution of charged particles (ions) across a cell membrane. This difference in concentration creates an electrochemical potential that can be harnessed by cells to perform various functions. For example, secondary active transporters utilize ion gradients to move molecules against their concentration gradient.

proteins

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

Proteins are the workhorses of the cell, carrying out essential tasks such as catalyzing reactions, transporting molecules, providing structural support, and regulating cellular processes. They are made up of chains of amino acids, folded into complex three-dimensional structures that determine their specific function.

cell membranes

Thin, flexible barriers that surround cells and regulate the passage of substances in and out.

Cell membranes are composed of a lipid bilayer with embedded proteins. They act as selective barriers, controlling the movement of molecules across them. This regulation is essential for maintaining cellular homeostasis and carrying out vital functions.

simulations

Computer models used to study and predict the behavior of complex systems.

Simulations are powerful tools used in various fields, including biotechnology, to understand complex phenomena. By creating computer models that mimic real-world processes, researchers can explore different scenarios and gain insights into how systems behave.
