Why Protein Structure Matters
Structure Meets Function
Proteins are the workhorses of life, carrying out a vast array of functions in every living organism. A protein's structure dictates how it interacts with other molecules, influencing its ability to bind to targets, catalyze reactions, and participate in signaling pathways. Even minor alterations in structure can significantly impact a protein's activity and behavior.
Utilizing accurate recombinant proteins is paramount to effective biopharmaceutical development.

3D Protein Structure FAQs
The Structure Lab specializes in creating 3D models of protein structures. It supports research and drug discovery by providing accurate visualizations of protein folding, binding sites, and molecular architecture relevant to biological function.
A protein’s structure determines how it interacts with other molecules. Structural insights help researchers predict binding affinities, assess conformational stability, and design targeted therapeutics with improved specificity and efficacy.
Protein structures are analyzed using a combination of computational modeling, structural databases, and experimental data from sources like X-ray crystallography or cryo-electron microscopy.
Digital models are generated using structural informatics and bioinformatics tools. These are then converted into tangible 3D-printed representations to visualize folds, domains, and active sites.
3D-printed models offer a physical, tactile perspective of protein architecture, allowing researchers to better understand spatial relationships and surface features that influence biological activity.
Examples include MHC Class I, CCR8, and the TCR-CD3 complex. Each model corresponds to a recombinant protein offered in the catalog and illustrates relevant functional domains.
Structural accuracy ensures that recombinant proteins mimic their native conformation, which is essential for proper folding, target binding, and functional assays in biopharmaceutical development.
The lab aims to bridge digital structure prediction with hands-on scientific insight. Its mission is to deepen understanding of protein behavior and accelerate translational research in the life sciences.
