Abstract

Myosin XVI (Myo16), a vertebrate-specific motor protein, is a recently discovered member of the myosin superfamily. The detailed functionality regarding myosin XVI requires elucidating or clarification; however, it appears to portray an important role in neural development and in the proper functioning of the nervous system. It is expressed in the largest amount in neural tissues in the late embryonic-early postnatal period, specifically the time in which neuronal cell migration and dendritic elaboration coincide. The impaired expression of myosin XVI has been found lurking in the background of several neuropsychiatric disorders including autism, schizophrenia and/or bipolar disorders. Two principal isoforms of class XVI myosins have been thus far described: Myo16a, the tailless cytoplasmic isoform and Myo16b, the full-length molecule featuring both cytoplasmic and nuclear localization. Both isoforms contain a class-specific N-terminal ankyrin repeat domain that binds to the protein phosphatase catalytic subunit. Myo16b, the predominant isoform, exhibits a diverse function. In the cytoplasm, it participates in the reorganization of the actin cytoskeleton through activation of the PI3K pathway and the WAVE-complex, while in the nucleus it may possess a role in cell cycle regulation. Based on the sequence, myosin XVI may have a compromised ATPase activity, implying a potential stationary role.
