WebMay 15, 1996 · and myosin (Fig. 2) poses several major questions and points to significant differences between these motors. It is obvious that the myosin head is considerably larger than the motor domain of kinesin and yet kinesin has a step size of ~80 Å [5] which is similar to that of myosin [9,10] (the step size for myosin is still the subject of con- WebIn humans, the 39 myosin genes are categorized into 13 classes, as shown in Figure 1. Per definition, class-2 myosins which encompass the myosins involved in muscle contraction are referred to as ‘conventional,’ all other myosins as ‘unconventional.’
