RESEARCH: CANCER
FOLDING PROJECT #17729 PROFILE

The project relates to studying how proteins move molecules across cell membranes using energy from ions. These proteins are important for many bodily functions and are targets for drugs treating diseases like cancer and diabetes. Simulations will help us understand how these proteins work across different types of cells.

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 essential proteins found in all living organisms. They use the energy from an ion gradient to move different molecules across cell membranes. This process is vital for many cellular functions, including nutrient uptake, waste removal, and signal transduction. Many secondary active transporters are targets for drugs used to treat diseases like cancer, diabetes, and neurological disorders.

Ion gradient

A difference in ion concentration across a cell membrane.

An ion gradient refers to an uneven distribution of charged ions (like sodium or potassium) across a cell membrane. This difference in concentration creates an electrical potential that can be used to power cellular processes, such as nerve impulse transmission and muscle contraction.

Cell membranes

The outer boundary of a cell that separates its internal environment from the outside.

Cell membranes are thin, flexible barriers that surround all living cells. They are composed primarily of lipids and proteins and play a crucial role in regulating what enters and exits the cell. This selective permeability is essential for maintaining cellular homeostasis and function.

Proteins

Large complex molecules essential for virtually all biological processes.

Proteins are the workhorses of cells, carrying out a wide range of functions including catalyzing biochemical reactions, transporting molecules, providing structural support, and regulating cellular processes. They are composed of chains of amino acids folded into specific three-dimensional shapes that determine their function.

Drug targets

Molecules or biological processes that are targeted by drugs to treat diseases.

Drug targets are specific molecules or pathways involved in disease processes. By inhibiting or activating these targets, drugs can modulate cellular functions and alleviate symptoms. Identifying effective drug targets is crucial for developing new therapies.

Cancer

Uncontrolled growth and spread of abnormal cells.

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. These cells can invade surrounding tissues and metastasize to distant organs, leading to various complications. Cancer treatment often involves surgery, chemotherapy, radiation therapy, or immunotherapy.

---

Diabetes

Metabolic disorder characterized by high blood sugar levels.

Diabetes is a chronic metabolic disorder characterized by elevated blood sugar levels. It occurs when the body either doesn't produce enough insulin or can't effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar levels. Diabetes can lead to various complications, including heart disease, stroke, blindness, and nerve damage.

Neurological disorders

Conditions affecting the nervous system.

Neurological disorders encompass a wide range of conditions affecting the brain, spinal cord, and peripheral nerves. They can manifest as cognitive impairments, movement disorders, sensory disturbances, or emotional changes. Examples include Alzheimer's disease, Parkinson's disease, multiple sclerosis, and epilepsy.
