Predicted to enable actin filament binding activity and microfilament motor activity. Involved in regulation of protein localization. Located in several cellular components, including brush border; growth cone; and membrane raft. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 48 and sensorineural hearing loss. Orthologous to human MYO1A (myosin IA).
