Comparisons with the other members of the N-5 subgroup revealed greatest similarity within the motor domain (47-50% identity) (figure 5).

Among the class XI myosins the similarity ranges from 40-85% (full length) and 61-91% (motor domain).

The motor domain in all cases is in the amino-terminal region.

Their motor domains have 93% similarity.

Phylogenetic analysis is often based on the motor domain of the myosins.

Their motor domains are 91.6% identical.

It is specifically a kinesin-like protein with a motor domain situated in the middle portion of its heavy chain.

Members of the kinesin superfamily have a highly conserved motor domain.

In addition to the motor domain, most kinesins have a coiled-coil region.

The kinesin-13 family, unlike other kinesins, has an internally positioned motor domain.
