This entry represents the lever arm from the unconventional myosin 6 proteins, the only class of myosin that has been shown to move toward the minus-end of actin filaments. This domain comprises an insert (Insert2) that binds the structural calmodulin (CaM) followed by the IQ motif and a proximal tail domain described as the lever arm extension [1-5]. The lever arm amplifies the conformational changes in the motor into a movement on the order of nanometers known as the powerstroke.	Domain
