RESEARCH: CANCER
FOLDING PROJECT #16951 PROFILE

This project relates to understanding how proteins fold. Scientists are using computer simulations to study how small changes in protein structure affect their ability to bind to other molecules. This could lead to the development of new cancer treatments called "affibody" therapeutics.

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 structural motif in proteins characterized by a helix shape.

Alpha-helical hairpins are a type of protein structure formed by a short segment of amino acids that coil into a helical shape. These structures are important for many biological functions and are often found in proteins involved in signal transduction, DNA binding, and cell adhesion.

disulfide cross-linkers

Covalent bonds between sulfur atoms in cysteine amino acids.

Disulfide cross-linkers are covalent bonds that form between two cysteine amino acids within a protein. These bonds help stabilize the protein structure and can influence its function. They are often found in proteins that need to be particularly stable, such as those exposed to harsh environments.

sequence variants

Variations in the DNA sequence of a gene.

Sequence variants are alterations in the DNA code that make up a gene. These variations can lead to changes in the protein produced by the gene, which can have a wide range of effects on an organism's traits and health.

molecular simulation methods

Computer-based techniques to model and simulate molecular interactions.

Molecular simulation methods use computer algorithms to mimic the behavior of molecules at an atomic level. These simulations can be used to study a wide range of phenomena, such as protein folding, drug binding, and chemical reactions.

protein binder scaffolds

Structural frameworks designed to bind specific proteins.

Protein binder scaffolds are three-dimensional structures that are engineered to specifically bind to target proteins. These scaffolds can be used as the basis for developing new drugs and therapies.

affibody

A type of engineered protein binding scaffold.

Affibody is a trademark name for a class of small proteins that bind to specific target molecules with high affinity and specificity. They are often used as therapeutic agents or diagnostic tools.

cancer therapeutics

Treatments designed to combat cancer.

Cancer therapeutics are a wide range of treatments aimed at preventing, diagnosing, and treating cancer. These treatments can include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapies.
