Predicted to enable microfilament motor activity and protein serine/threonine kinase activity. Predicted to be involved in auditory receptor cell stereocilium organization; cochlea morphogenesis; and sensory perception of sound. Predicted to act upstream of or within positive regulation of filopodium assembly; protein phosphorylation; and regulation of actin filament length. Predicted to be located in filopodium tip; photoreceptor inner segment; and photoreceptor outer segment. Predicted to be part of myosin complex. Predicted to be active in stereocilium tip. Orthologous to human MYO3B (myosin IIIB). [provided by Alliance of Genome Resources, Apr 2022]
