RESEARCH: CANCER
FOLDING PROJECT #16946 PROFILE

This project relates to understanding how small proteins fold into specific shapes using computer simulations. By studying how chemical bonds and slight changes in the protein's code affect its folding, researchers hope to design better 'affibody' drugs that can target cancer cells.

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 hairpins

Structural motif in proteins consisting of alpha helices.

Alpha-helical hairpins are a common structural element found in proteins. They consist of two alpha helices connected by a short loop region. These structures are important for protein stability and function.

---

disulfide cross-linkers

Covalent bonds between cysteine amino acids in proteins.

Disulfide cross-linkers are covalent bonds formed between two sulfur atoms from cysteine amino acids within a protein. These bonds contribute to protein stability and can influence folding patterns.

---

sequence variants

Alterations in the amino acid sequence of a protein.

Sequence variants are changes in the order of amino acids within a protein. These variations can arise naturally or be introduced through genetic engineering and can affect protein function.

---

folding thermodynamics

The study of energy changes during protein folding.

Folding thermodynamics examines the energy factors that drive protein folding. This includes the forces that stabilize folded structures and the energy required to unfold proteins.

---

folding kinetics

The rate at which proteins fold.

Folding kinetics describes the speed at which proteins transition from a unfolded state to a folded, functional state. Factors influencing folding kinetics include temperature and protein sequence.

---

protein binder scaffolds

Structural frameworks for binding to specific target molecules.

Protein binder scaffolds are designed protein structures that can bind to specific targets like proteins or small molecules. They serve as the basis for developing drugs and therapeutic agents.

---

affibody

A specific type of engineered protein binder scaffold.

Affibody is a trademark for a class of engineered proteins that bind to specific targets with high affinity. These small proteins are used in research and therapeutic applications.

cancer therapeutics

Medicinal agents designed to treat cancer.

Cancer therapeutics encompass a range of treatments aimed at combating the growth and spread of cancerous cells. This includes chemotherapy, targeted therapies, immunotherapy, and radiation therapy.
