Kif7 (PDB: 4A14) is a member of the Kinesin 4 superfamily. There are currently many speculations of it being involved in several different diseases. It is a plus-end-directed motor protein and putative ciliary motor that also interacts with Gli proteins. One other interesting thing about this figure is all the visible tails throughout the molecule. Most likely these are actually loops that are just hard to capture in the visualization (due to their constant movement about the structure).
