Unconventional myosin-VIIa (MYO7A)

Myosins are actin-based motor molecules with ATPase activity. Unconventional myosins serve in intracellular movements.

Their highly divergent tails bind to membranous compartments, which are then moved relative to actin filaments. In the retina, plays an important role in the renewal of the outer photoreceptor discs.
