RESEARCH: CANCER
FOLDING PROJECT #16992 PROFILE

This project relates to understanding how tiny proteins fold into shapes and how we can change those shapes with special chemical links. By learning this, scientists hope to design better cancer treatments.

These simulations are designed to test our understanding the folding mechanism of alpha-helical hairpins.

We are trying to study how disulfide cross-linkers and sequence variants affect the folding thermodynamics and kinetics of these proteins, to learn how we might better use molecular simulation methods to design effective protein binder scaffolds, for use as "affibody" cancer therapeutics, for example.

alpha-helical hairpins

A type of protein secondary structure characterized by a helical shape.

Alpha-helical hairpins are small, structured sections of proteins that form a helix shape. They are important for how proteins fold and interact with other molecules. Understanding these structures can help in designing new drugs and therapies.

disulfide cross-linkers

Covalent bonds between sulfur atoms in cysteine amino acids.

Disulfide cross-linkers are strong chemical bonds that can form within proteins. They help stabilize protein structures and are often used to modify proteins for specific purposes, such as creating more stable drugs.

sequence variants

Variations in the DNA sequence of a gene.

Sequence variants are changes in the DNA code that can affect how a protein is made. These variations can be harmless, beneficial, or harmful and play a role in diseases.

folding thermodynamics

The study of the energy changes associated with protein folding.

Folding thermodynamics describes how proteins change shape and how much energy is involved. Understanding these principles is crucial for designing new drugs and therapies.

folding kinetics

The rate at which proteins fold.

Folding kinetics describes how quickly proteins change shape. This is important for understanding how cells function and how diseases develop.

protein binder scaffolds

Structural frameworks used to create drugs that bind to specific targets.

Protein binder scaffolds are the basic building blocks for many new drugs. They are designed to attach to specific proteins in the body and block their function.

affibody

An engineered protein based on the Z domain of staphylococcal protein A.

Affibody is a type of protein drug that can bind to specific targets in the body. They are small and stable, making them useful for treating cancer and other diseases.

cancer therapeutics

Drugs used to treat cancer.

Cancer therapeutics are medications designed to kill or slow the growth of cancer cells. They work in various ways and are essential for treating many types of cancer.
