Predicted to enable several functions, including ADP binding activity; calmodulin binding activity; and plus-end directed microfilament motor activity. Predicted to be involved in auditory receptor cell stereocilium organization and cochlea morphogenesis. Predicted to act upstream of or within several processes, including positive regulation of filopodium assembly; protein phosphorylation; and sensory perception of sound. Predicted to be located in several cellular components, including filopodium tip; photoreceptor inner segment; and stereocilium tip. Predicted to be part of filamentous actin. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 30. Orthologous to human MYO3A (myosin IIIA). [provided by Alliance of Genome Resources, Apr 2022]
