RESEARCH: CANCER
FOLDING PROJECT #16986 PROFILE

This project relates to studying how tiny protein structures called alpha-helical hairpins fold and what makes them stable. By changing these structures, we hope to design better 'affibody' drugs that can target and fight cancer.

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 type of protein structure characterized by alpha-helices forming a hairpin shape.

Alpha-helical hairpins are a common structural motif in proteins. They consist of two alpha-helices connected by a loop region, creating a hairpin-like shape. This structure is important for various protein functions, including binding to other molecules and mediating interactions within cells.

disulfide cross-linkers

Covalent bonds formed between sulfur atoms in cysteine amino acids within a protein.

Disulfide cross-linkers are covalent bonds that form between two sulfur atoms in cysteine amino acids. These bonds play a crucial role in stabilizing the structure of proteins and influencing their function. They can be important for proper folding and maintaining the shape of proteins, especially in challenging environments.

sequence variants

Alterations in the DNA sequence of a gene that can result in changes to the protein it encodes.

Sequence variants are variations in the DNA code that can lead to differences in the amino acid sequence of proteins. These changes can have a range of effects, from subtle alterations in protein function to complete loss of function. Studying sequence variants is essential for understanding genetic diseases and developing new therapies.

molecular simulation methods

Computer-based techniques used to model and predict the behavior of molecules.

Molecular simulation methods use algorithms to simulate the movements and interactions of atoms and molecules. These simulations can be used to study a wide range of biological processes, such as protein folding, drug binding, and enzyme catalysis. They are valuable tools for understanding complex systems at the molecular level.

protein binder scaffolds

Structural frameworks designed to bind specifically to target proteins.

Protein binder scaffolds are engineered protein structures that serve as templates for binding to specific target proteins. These scaffolds can be used in the development of new drugs by targeting and inhibiting disease-causing proteins or delivering therapeutic molecules to specific cells.

affibody

A small protein domain that binds with high affinity and specificity to a target.

Affibody is a type of engineered protein that exhibits high binding affinity for specific targets. It is derived from the Z domain of Protein A and has been extensively studied for its potential in drug development. Affibody molecules can be used as therapeutic agents, diagnostic tools, and research reagents.

cancer therapeutics

Medical treatments designed to combat cancer.

Cancer therapeutics encompass a broad range of medical interventions aimed at treating and managing cancer. These include surgery, radiation therapy, chemotherapy, immunotherapy, and targeted therapies. The goal of cancer therapeutics is to eliminate or control cancer cells while minimizing harm to healthy tissues.
