RESEARCH: CANCER
FOLDING PROJECT #16933 PROFILE

This project relates to studying how tiny proteins fold and how changes to their structure affect their ability to bind to other molecules. Understanding this could help us design better cancer treatments.

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

A structural motif in proteins characterized by a helical shape.

Alpha-helical hairpins are common structures found in proteins. They consist of a section of the protein chain that forms an alpha helix, followed by another short stretch of chain that folds back on itself to form a hairpin shape. These structures play important roles in protein function and stability.

disulfide cross-linkers

Covalent bonds between sulfur atoms in cysteine amino acids.

Disulfide cross-linkers are strong chemical bonds that can form between two sulfur atoms within proteins. They play a crucial role in stabilizing protein structure and influencing its function. These bonds contribute to the overall shape and stability of proteins, particularly in their extracellular environment.

sequence variants

Variations in the DNA sequence of a gene.

Sequence variants are changes in the order of DNA building blocks (nucleotides) within a gene. These variations can lead to alterations in protein structure and function. Understanding sequence variants is crucial for studying genetic diseases and developing personalized medicine approaches.

folding thermodynamics

The study of energy changes associated with protein folding.

Folding thermodynamics explores the energy factors driving the process of proteins adopting their three-dimensional shapes. This field investigates how various interactions between amino acids influence protein stability and the likelihood of a protein folding correctly.

protein binder scaffolds

Framework structures designed to bind specifically to target proteins.

Protein binder scaffolds are foundational elements in the design of new drugs. These engineered structures possess a specific shape that allows them to tightly attach to particular target proteins within the body. This binding can inhibit or activate protein function, leading to therapeutic effects.

affibody

A small protein scaffold with high affinity binding to specific targets.

Affibody is a proprietary technology that utilizes genetically engineered proteins known as affibodies. These tiny proteins are designed to bind tightly and specifically to target molecules, making them valuable tools for drug development.

cancer therapeutics

Medicines used to treat cancer.

Cancer therapeutics encompass a broad range of treatments aimed at combating various types of cancers. These include chemotherapy drugs, targeted therapies, immunotherapy agents, and radiation therapy.
