RESEARCH: CANCER
FOLDING PROJECT #16950 PROFILE

This project relates to understanding how small proteins fold into specific shapes. Scientists are using computer simulations to see how tiny chemical bridges and slight changes in the protein's code affect its folding. The goal is to learn how to design better, more effective proteins that can be used as cancer treatments.

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

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

A type of protein structure characterized by a spiral shape.

Alpha-helices are common structural motifs in proteins. They consist of a polypeptide chain that coils into a right-handed helix stabilized by hydrogen bonds between amino acids spaced four residues apart.

---

disulfide cross-linkers

Covalent bonds between cysteine amino acids in proteins.

Disulfide cross-linkers are covalent bonds formed between sulfur atoms of two cysteine amino acids within a protein. These bonds contribute to the stability and folding of proteins.

---

sequence variants

Variations in the DNA sequence of a gene.

Sequence variants are alterations in the order of nucleotides within a gene. These variations can lead to changes in protein structure and function.

---

folding thermodynamics

The study of energy changes associated with protein folding.

Folding thermodynamics investigates the energy changes that occur when a protein folds into its native conformation. This involves factors such as enthalpy and entropy.

---

molecular simulation

Computer-based modeling of biological systems.

Molecular simulations use computational algorithms to model the behavior of atoms and molecules. These simulations can be used to study protein folding, drug binding, and other biomolecular processes.

---

protein binder scaffolds

Structural frameworks for binding to target molecules.

Protein binder scaffolds are designed to specifically bind to target proteins or other biomolecules. These scaffolds can be used as the basis for therapeutic antibodies and other drug candidates.

---

affibody

A type of small protein scaffold that binds to specific targets.

Affibody is a registered trademark for a class of engineered proteins that bind tightly and specifically to their target molecules. They are used as imaging agents, therapeutic antibodies, and diagnostic tools.

cancer therapeutics

Drugs used to treat cancer.

Cancer therapeutics are medications designed to kill or inhibit the growth of cancerous cells. They can work by targeting specific molecules involved in cancer cell growth and survival.
