RESEARCH: CANCER
FOLDING PROJECT #16965 PROFILE

This project relates to understanding how tiny protein structures called hairpins fold. By studying the effects of chemical links and slight changes in their code, researchers hope to design better proteins that can be used as cancer drugs.

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 secondary protein structure characterized by a coiled shape.

Alpha-helices are common structural elements in proteins. They form a spiral shape due to hydrogen bonding between amino acids in the polypeptide chain. This shape is important for protein stability and function.

disulfide cross-linkers

Covalent bonds formed between two cysteine amino acids in a protein.

Disulfide cross-links are strong covalent bonds that can stabilize protein structure. They form between sulfur atoms in cysteine residues and are important for the proper folding and function of many proteins.

sequence variants

Variations in the order of amino acids within a protein sequence.

Sequence variants can alter a protein's structure, function, and stability. They are often studied to understand how genetic changes affect protein properties and disease susceptibility.

thermodynamics

The study of energy changes in chemical and physical processes.

Thermodynamics describes the heat flow and energy changes associated with biological processes. In protein folding, thermodynamics determines the stability and equilibrium of different protein conformations.

kinetics

The study of the rates of chemical reactions.

Kinetics focuses on how fast reactions occur and the factors that influence reaction speed. In protein folding, kinetics describes the time required for a protein to adopt its stable conformation.

molecular simulation

Computational methods used to model and predict the behavior of molecules.

Molecular simulations are widely used in drug discovery and materials science to understand how molecules interact and function. They can help design new drugs, optimize existing therapies, and develop novel materials.

protein binder scaffolds

Structural frameworks used to design proteins that bind specifically to target molecules.

Protein binder scaffolds are versatile tools in drug discovery. They can be engineered to recognize specific disease-related targets and deliver therapeutic payloads.

affibody

A type of engineered protein scaffold with high affinity for specific targets.

Affibody molecules are small and stable proteins that can bind to various targets with high specificity. They have potential applications in diagnostics, imaging, and therapeutic drug delivery.

cancer therapeutics

Medicinal treatments used to prevent, diagnose, and treat cancer.

Cancer therapeutics encompass a wide range of approaches, including surgery, chemotherapy, radiation therapy, and targeted therapies. They aim to control or eliminate cancerous cells while minimizing damage to healthy tissues.
