In modern biochemistry, structural determination is essential for understanding the function of biomolecules. Scientists in Glenn Millhauser's laboratory use peptide synthesis, nuclear magnetic resonance spectroscopy (NMR), and electron paramagnetic spin resonance spectroscopy (EPR) to examine the structure and analyze the function of proteins that have been implicated in several debilitating diseases. This includes the prion protein, which is responsible for mad cow disease and the related human affliction, Creutzfeldt-Jakob disease. They have also examined a novel signaling molecule, called AGRP, which is involved in energy balance and metabolic pathologies, such as diabetes and obesity.

Melanocortin MC₁ receptor in human genetics and model systems.
...Published in European Journal of Pharmacology
The melanocortin MC(1) receptor is a G-protein coupled receptor expressed in the melanocytes of the skin and hair and is known for its key role in the regulation of human pigmentation. Melanocortin MC(1) receptor activation after ultraviolet radiation exposure results in a switch from the red/yellow pheomelanin to the brown/black eumelanin pigment ...

Distance-dependent Fluorescence Quenching and Binding of CdSe Quantum Dots by Functionalized Nitroxide Radicals.
Published in The Journal of Physical Chemistry C
Quantum dot (QD) fluorescence is effectively quenched at low concentration by nitroxides bearing amine or carboxylic acid ligands. The association constants and fluorescence quenching of CdSe QDs with these derivatized nitroxides have been examined using electron paramagnetic resonance (EPR) and fluorescence spectroscopy. The EPR spectra in the non...
