RESEARCH: CANCER
FOLDING PROJECT #16931 PROFILE

This project relates to understanding how small proteins fold into specific shapes. By changing the protein's building blocks and connections, scientists can see how this affects its stability and folding speed. The goal is to learn how to design these proteins as 'affibody' cancer drugs that bind specifically to tumors.

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 helix shape.

Alpha-helices are common secondary structures in proteins. They form when a polypeptide chain coils into a spiral shape held together by hydrogen bonds between amino acids.

---

hairpins

A type of protein structure characterized by a loop followed by a turn back on itself.

Hairpins are small, folded regions within proteins. They are formed when a polypeptide chain folds back upon itself, creating a hairpin-like shape.

---

disulfide cross-linkers

Covalent bonds between cysteine amino acids in proteins.

Disulfide cross-linkers are strong covalent bonds that form between two cysteine amino acids within a protein. They contribute to protein stability and folding.

---

sequence variants

Variations in the DNA sequence of a gene.

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

---

molecular simulation

A computer-based method for modeling and simulating biological processes.

Molecular simulations use mathematical models to simulate the behavior of molecules and atoms. This allows scientists to study complex biological systems in a virtual environment.

---

protein binder scaffolds

Three-dimensional structures that can bind to specific target proteins.

Protein binder scaffolds are designed to bind to specific target proteins, such as those involved in disease pathways. They serve as a basis for developing therapeutic drugs.

---

affibody

A small engineered protein with high affinity for a target antigen.

Affibody is a trademarked term for a type of engineered protein that binds to specific targets. They are used in various applications, including diagnostics and drug delivery.

cancer therapeutics

Medicinal treatments for cancer.

Cancer therapeutics encompass a wide range of treatments aimed at preventing, diagnosing, and treating various types of cancer.
