RESEARCH: CANCER
FOLDING PROJECT #16954 PROFILE

This project relates to studying how tiny protein structures fold using computer simulations. By changing these structures slightly, we can see how they affect how well the proteins bind to other molecules. This knowledge could help us design new cancer treatments that latch onto specific 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 type of protein structure characterized by a helix shape.

Alpha-helical hairpins are a common structural motif found in proteins. They consist of a segment of the polypeptide chain that forms a coiled helix shape. These structures are important for protein function and stability.

---

disulfide cross-linkers

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

Disulfide cross-linkers are covalent bonds that can form between sulfur atoms in cysteine amino acids within a protein. These bonds help to stabilize the protein's three-dimensional structure and influence its function.

---

sequence variants

Variations in the DNA sequence of a gene.

Sequence variants are changes in the order of nucleotides (DNA building blocks) within a gene. These variations can lead to differences in protein structure and function.

---

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. It helps us understand the stability and conformational changes of proteins.

---

folding kinetics

The rate and mechanism of protein folding.

Folding kinetics examines how quickly proteins fold into their functional shapes and the steps involved in this process. It's crucial for understanding protein function and disease.

---

protein binder scaffolds

Structural frameworks designed to bind to specific target proteins.

Protein binder scaffolds are engineered structures that can selectively bind to target proteins. They serve as the basis for developing therapeutic drugs and diagnostic tools.

---

affibody

A recombinant protein-binding domain.

Affibody is a type of engineered protein that can bind to specific target molecules with high affinity. They are used in various applications, including diagnostics and therapeutics.

cancer therapeutics

Medicinal treatments for cancer.

Cancer therapeutics encompass a wide range of medical interventions aimed at treating and managing various types of cancer. These therapies include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy.
