The recent discovery of a dysfunctional mutation of GPIHBP1 in a man with chylomicronemia implicates this protein in human physiology. GPIHBP1 can be placed in the larger context of other molecular participants in chylomicron docking and hydrolysis on microvascular endothelium, caloric delivery, and remnant lipoprotein generation. Critical questions include the regulation—and dysregulation—of these processes in states of overnutrition, underexertion, obesity, insulin resistance, and diabetes.
