RESEARCH: CANCER
FOLDING PROJECT #17769 PROFILE

This project explores how special proteins move molecules across cell walls using the power of ion gradients. These proteins are found everywhere and play a big role in treating diseases like cancer and diabetes. Studying them helps us understand how they work across different types of organisms.

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 ions to transport molecules across cell membranes.

Secondary active transporters are essential proteins found in all living organisms. They utilize an existing ion gradient to power the movement of various molecules across cell membranes. This process is crucial for many cellular functions, including nutrient uptake, waste removal, and signal transduction. Due to their importance in various physiological processes, secondary active transporters are also attractive drug targets for treating a wide range of diseases.

Proteins

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

Proteins are the workhorses of cells, responsible for carrying out countless tasks essential for life. They can act as enzymes to speed up chemical reactions, provide structural support, transport molecules, and participate in signaling pathways. The diversity of protein functions is immense, reflecting their crucial role in all aspects of biology.

Cell membranes

Thin barriers that surround cells, regulating the passage of molecules in and out.

Cell membranes are essential for compartmentalizing cellular processes and maintaining cell integrity. They act as selective barriers, allowing certain molecules to pass through while restricting others. This control over molecular movement is crucial for maintaining cellular homeostasis and enabling communication with the external environment.

Ion gradient

A difference in concentration of charged ions across a membrane.

An ion gradient is a fundamental concept in cellular energy and transport. It refers to an uneven distribution of charged particles (ions) across a membrane. This difference in concentration creates an electrochemical potential that can be harnessed by cells to power various processes, such as the movement of molecules across membranes.

Drug targets

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

Drug targets are key components of pharmaceutical research and development. By identifying molecules or cellular pathways that contribute to disease progression, scientists can design drugs that specifically interfere with these targets, aiming to alleviate or cure the disease. Understanding drug targets is crucial for developing effective and safe medications.

Simulations

Computer models used to represent and study biological systems.

Simulations are powerful tools in bioinformatics, allowing researchers to explore complex biological processes without conducting physical experiments. By creating mathematical models that mimic real-world interactions, scientists can gain insights into how cells function, predict the effects of genetic mutations, and design new therapies.
