Research Description

Dr. Sweeney's research interests include the molecular motors of the myosin superfamily. Notable among his accomplishments on molecular motors was the first visualization of structural rearrangement of the myosin lever arm, a detailed analysis of how processive myosins are engineered, a demonstration of the structural changes induced by actin-binding and nucleotide release, and the discovery and molecular dissection of the only known reverse-direction myosin. He is currently working to understand the fundamental motor mechanism resulting from myosin’s interaction with actin. He also is seeking to understand design specializations of a number of unconventional myosins, with a primary focus on myosin VI.

Much of Dr. Sweeney’s research program is translational in focus, and has produced highly cited research on inherited forms cardiovascular disease and on the skeletal and cardiac aspects of muscular dystrophy. Dr. Sweeney has been Director of a Paul Wellstone Muscular Dystrophy Cooperative Center since 2005. Dr. Sweeney is actively developing therapeutics for rare diseases with a focus on the muscular dystrophies. While he is primarily working with small molecules and biologicals, he also is evaluating gene therapy approaches.
