Myosin-XVIIIb is a protein that in humans is encoded by the MYO18Bgene.[5][6][7]
The protein encoded by this gene may regulate muscle-specific genes when in the nucleus and may influence intracellular trafficking when in the cytoplasm. The encoded protein functions as a homodimer and may interact with F actin. Mutations in this gene are associated with lung cancer.[7]
