RESEARCH: CANCER
FOLDING PROJECT #16952 PROFILE

This project relates to understanding how proteins fold into specific shapes. By studying tiny changes in protein structure and adding special 'links', scientists hope to design better 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

A secondary structure in proteins characterized by a helix conformation.

Alpha-helical hairpins are a type of protein structure where a short segment of the protein chain forms a spiral shape called an alpha helix. These structures are often found in loops or bends within larger proteins and play important roles in protein folding and function.

disulfide cross-linkers

Covalent bonds between cysteine amino acids in proteins that stabilize protein structure.

Disulfide cross-linkers are chemical bonds formed between two sulfur atoms from cysteine amino acids within a protein. These bonds help to stabilize the three-dimensional shape of proteins, making them more resistant to unfolding and degradation.

---

sequence variants

Alterations in the DNA sequence that code for a protein, resulting in changes to its amino acid sequence.

Sequence variants are changes in the DNA code that can result in different versions of a protein. These variations can affect a protein's structure, function, and interactions with other molecules.

folding thermodynamics

The study of energy changes associated with protein folding.

Folding thermodynamics explores the energy factors that influence how proteins fold into their specific three-dimensional shapes. Understanding these principles is crucial for designing and engineering stable and functional proteins.

---

folding kinetics

The rate and mechanisms of protein folding.

Folding kinetics examines how quickly proteins fold into their final shapes and the steps involved in the process. This knowledge is essential for understanding protein function and developing strategies to control protein assembly.

protein binder scaffolds

Three-dimensional protein structures that can be designed to bind specifically to target molecules.

Protein binder scaffolds are like frameworks built from proteins that are designed to attach to specific molecules. These scaffolds are used in drug development to create targeted therapies that interact with disease-causing proteins.

affibody

Affibody (Antibody Fragment-Based Drug)

Affibody is a type of engineered protein that acts as a highly specific targeting molecule. These molecules are smaller than traditional antibodies and can be used to deliver drugs or other therapeutic agents to specific cells or tissues.

cancer therapeutics

Medical treatments designed to fight and treat cancer.

Cancer therapeutics are medications or therapies used to diagnose, treat, or prevent cancer. These treatments can work by destroying cancer cells, slowing their growth, or relieving symptoms associated with the disease.
