Dr. Daleke's interests lie in the generation and maintenance of transmembrane phospholipid asymmetry which are essential for the function of biological membranes, yet the mechanism underlying these fundamental processes remains unclear. Our research effort is designed to understand how phospholipids are assembled in biological membranes and how the resulting phospholipid asymmetry is maintained. Phospholipid transporters, or "flippases," such as the recently discovered aminophospholipid translocator, represent an interesting new class of proteins that may play a key role in the assembly and organization of phospholipids in biological membranes. These enzymes require energy in the form of ATP, have strict phospholipid structural requirements, and are unique in their ability to transport lipids across membranes. Our goal is to elucidate the structure, function, and biological significance of these proteins.
