The protein nNOS-mu, which is just one form of the nNOS protein, is essential for skeletal muscle health, and signaling via nNOS-mu is commonly reduced in neuromuscular disease. Now, Justin Percival and colleagues, at the University of Washington, Seattle, have identified a crucial role for the nNOS-beta form of nNOS in mouse skeletal muscle, where it enables skeletal muscle to maintain force production during and after exercise.
