RESEARCH: CANCER
FOLDING PROJECT #17736 PROFILE

This project looks at how proteins use ions to move molecules across cell membranes. These proteins are important for many bodily functions and are also drug targets for diseases like cancer and diabetes. By studying them, we can learn more about how cells work.

Note: This TLDR is a simplication and may not be 100% accurate.

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 transporters

Proteins that use ions to transport molecules across cell membranes.

Secondary active transporters are a crucial type of protein found in all living organisms. They utilize the energy stored in ion gradients to move various molecules across cell membranes. This process is essential for many cellular functions, including nutrient uptake, waste removal, and signal transduction. Due to their importance in various biological processes, secondary active transporters have become attractive targets for drug development to treat diseases like cancer, diabetes, and neurological disorders.

Membrane transporters

Proteins that move molecules across cell membranes.

Membrane transporters are essential proteins embedded within the cell membrane. They facilitate the movement of various substances, such as nutrients, ions, and waste products, across the membrane barrier. This selective transport is crucial for maintaining cellular homeostasis, regulating signaling pathways, and enabling cells to interact with their environment.

Ion gradient

A difference in ion concentration across a membrane.

An ion gradient refers to the unequal distribution of ions (charged atoms) across a cell membrane. This concentration difference creates an electrochemical potential that drives various cellular processes. Ion gradients are essential for nerve impulse transmission, muscle contraction, and nutrient uptake.

Drug targets

Molecules or pathways that are altered to treat diseases.

Drug targets are specific biological molecules or cellular processes that are involved in the development or progression of a disease. By targeting these specific pathways, pharmaceutical drugs can aim to modulate their activity and alleviate disease symptoms. Identifying effective drug targets is a crucial step in the drug discovery process.

Cancer

A disease characterized by uncontrolled cell growth.

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. This uncontrolled proliferation arises from genetic mutations that disrupt normal cellular processes, leading to tumor formation and potentially life-threatening complications.

---

Diabetes

A metabolic disorder characterized by high blood sugar levels.

Diabetes is a chronic condition affecting how the body regulates blood sugar. It occurs when the pancreas does not produce enough insulin or when the body becomes resistant to insulin's effects. This leads to elevated glucose levels in the bloodstream, potentially damaging organs and tissues over time.

Neurological disorders

Conditions affecting the nervous system.

Neurological disorders encompass a wide range of conditions that affect the brain, spinal cord, and peripheral nerves. These disorders can manifest in various ways, including cognitive impairment, movement problems, sensory disturbances, and emotional changes. Examples include Alzheimer's disease, Parkinson's disease, and multiple sclerosis.
