Peak Performance

the structural biology of athletics and well-being

Athletes require bodies that are the best that is possible, all the way from molecules to muscles. By understanding the structure and function of our molecules, athletes can ensure that they are performing at their peak. This knowledge also informs the ways that we all can live our best lives, at all stages of our lives.

	G Protein-Coupled Receptor (GPCR) Paper Model GPCRs are a large family of membrane-embedded receptors, with structural features that have been preserved through the course of evolution. This model represents the shared structural features of all GPCRs. With the extracellular N-terminus, the protein chain folds to form a bundle of seven transmembrane alpha helices connected by 3 intracellular and 3 extracellular loops with the C-terminus reaching inside the cell.
	Insulin and Diabetes Poster Structural biology has revealed the details of insulin signaling and how this knowledge is being used to create new and better treatments for diabetes.
	How Neurons Communicate Video The billions of neurons in our nervous system are constantly communicating. The signals they send to each other are responsible for our thoughts, sensations, and actions. Learn how ions, ion channels, receptors, and neurotransmitters work together to enable the neuronal signaling process.
	Calcium Pump Video The calcium pump moves ions across cell membranes allowing the synchronized contraction of muscle cells.
	Bound! Protein-drug matching game Other Resource Bound! is a card game for students 12 and up, where players compete to match the most drugs to their protein targets.
	Exploring the Structural Biology of Health and Nutrition Article By understanding the molecular needs of our cells, we can ensure that our bodies operate at peak performance.
