RESEARCH: MEMBRANE TRANSPORT
FOLDING PROJECT #17930 PROFILE

This project looks at how sugar transporters work. These proteins move different types of sugars into and out of cells. The researchers want to understand how these transporters recognize and move such diverse molecules. This could help us design new drugs that specifically target certain transporters.

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

Membrane transporters are important for enabling molecules to go in and out of cells.

What is interesting is that while transporters typically have set functions, they can also transport molecules that do not necessarily relate to their function or cellular purpose.

For example, drugs often hijack transporters to enter cells without necessarily resembling the molecules or metabolites which that target transporter normally transports.

The goal of this project is to see how exactly a typical membrane transporter recognizes and transports molecules that look different from one another.

We choose a class of sugar transporters that transports a variety of different types of substrates to satisfy this goal.

Findings from this study can be generalized for the design of molecules (e.g., drugs) specific to a given transporter and its general mechanism.

Membrane transporters

Proteins embedded in cell membranes that facilitate the movement of molecules across.

Membrane transporters are essential proteins found in cell membranes. They act like gates, controlling the movement of various substances, such as nutrients and waste products, into and out of cells. This process is crucial for maintaining cellular function and homeostasis.

Drugs

Substances used to treat, cure, or prevent diseases.

Drugs are chemical substances designed to have a specific effect on the body. They can be used to treat a wide range of conditions, from infections to chronic diseases. Pharmacists and researchers work together to develop new drugs that are safe and effective.

Molecules

Smallest unit of a compound that retains its chemical properties.

Molecules are the building blocks of all matter. They are formed when two or more atoms bond together. Different types of molecules have different properties and functions. For example, water is a molecule made up of two hydrogen atoms and one oxygen atom.

Cellular purpose

The specific role or function that a cell performs within an organism.

Every cell in an organism has a specific job to do. This is known as its cellular purpose. For example, some cells are responsible for transporting nutrients, while others are involved in fighting infection.

Substrates

Substances that are acted upon by an enzyme.

Substrates are the molecules that enzymes work on. Enzymes are biological catalysts that speed up chemical reactions. The substrate binds to the active site of the enzyme, and the enzyme then catalyzes a reaction, transforming the substrate into a product.
