Extra actin filaments at the periphery of skeletal muscle myofibrils
Abstract
Myofibrils isolated from a variety of vertebrate muscle fibers have a set of peripheral filaments associated with the periphery of the Z line free to move away from the surface of the myofibril. Decoration with myosin subfragment 1 shows that these are actin filaments.
