A Point Mutation in the Regulatory Light Chain Reduces the Step Size of Skeletal Muscle Myosin by Sherwood, Jennifer J., Waller, Guillermina S., Warshaw, David M., Lowey, Susan, Spudich, James A.

“…Current evidence favors the theory that, when the globular motor domain of myosin attaches to actin, the light chain binding domain or "lever arm" rotates, and…”

Skeletal muscle myosin light chains are essential for physiological speeds of shortening by Lowey, Susan, Waller, Guillermina S, Trybus, Kathleen M

“…In muscle each myosin head contains a regulatory light chain (LC2) that is wrapped around the head/rod junction, and an alkali light chain that is distal to…”

Coupling of ATPase Activity and Motility in Smooth Muscle Myosin Is Mediated by the Regulatory Light Chain by Trybus, Kathleen M., Waller, Guillermina S., Chatman, Thereatha A.

“…Smooth muscle myosin acts as a molecular motor only if the regulatory light chain (RLC) is phosphorylated. This subunit can be removed from myosin by a novel…”
