RESEARCH: CANCER
FOLDING PROJECT #16988 PROFILE

This project relates to understanding how small proteins fold into specific shapes. By changing the protein's building blocks and adding special links, scientists can see how these changes affect the folding process. The goal is to learn how to design proteins that bind to specific targets, like cancer cells, which could lead to new 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 secondary structure in proteins characterized by a helix shape.

Alpha-helical hairpins are small, stable protein structures that form when a polypeptide chain curls into a spiral shape. These structures are important for many biological processes, including protein folding and function.

disulfide cross-linkers

Covalent bonds formed between cysteine amino acids in proteins.

Disulfide cross-linkers are strong chemical bonds that can stabilize the structure of proteins. They are formed when two sulfur atoms from cysteine amino acids react with each other. These bonds are important for the function and stability of many proteins.

sequence variants

Variations in the DNA sequence of a gene.

Sequence variants are changes in the order of nucleotides in a DNA sequence. These variations can lead to differences in protein structure and function.

folding thermodynamics

The study of the energy changes involved in protein folding.

Folding thermodynamics explores the energy relationships that govern how proteins fold into their specific three-dimensional shapes. This field is crucial for understanding protein function and designing new drugs.

molecular simulation

Computer-based methods used to model and simulate biological processes.

Molecular simulations use mathematical models to mimic the behavior of atoms and molecules in a system. This allows researchers to study complex biological processes at the atomic level.

protein binder scaffolds

Structural frameworks used to design proteins that bind to specific targets.

Protein binder scaffolds are designed to provide a framework for developing proteins that can specifically bind to target molecules. This technology is crucial for designing new drugs and therapies.

affibody

A small, engineered protein domain that binds to specific targets with high affinity.

Affibody is a type of engineered protein that acts as a miniature antibody. It binds tightly to specific targets, making it useful for various applications, such as drug delivery and diagnostics.

cancer therapeutics

Medications used to treat cancer.

Cancer therapeutics encompass a wide range of medications designed to combat cancer cells. These treatments aim to kill cancer cells, slow their growth, or prevent them from spreading.
