A protein in the Myosin family that is essential to intracellular motility (that is the movement of stuff within the cells). They move around vacuoles, and are often highly associated with the Golgi apparatus.

Mutation of Myosin 5 in yeast results in problems with protein secretion and is noticeable by the build up of vacuoles in the cytoplasm.
Myosin 5 is particularly concentrated in the brain and other nervous tissue where the transport of neurotransmitters down the length of neuron axons and its timely release into the synaptic clefts is essential.
