Muscle atrophy is a debilitating and life threatening disorder. It is associated with a number of diseases including cancer, diabetes, chronic obstructive pulmonary disease and AIDS and is a natural consequence of inactivity and aging. MuRF1 is an E3 ubiquitin ligase which has been implicated as a component of atrophy-associated proteolysis. It contains an amino terminal RING finger that mediates ubiquitin transfer along with a zinc finger and two coiled-coil domains in its central region. It is up-regulated in a number of different models of atrophy and interacts with numerous myofibrillar proteins as well as Cardiac Troponin I and Creatine Kinase. Deletion of MuRF1 in mice has been shown to inhibit skeletal muscle atrophy suggesting that it may be an important drug target for the prevention of muscle wasting.
