Myo3b - myosin IIIB

Enables microfilament motor activity and protein serine/threonine kinase activity. Involved in auditory receptor cell stereocilium organization; cochlea morphogenesis; and sensory perception of sound. Acts upstream of or within positive regulation of filopodium assembly; protein phosphorylation; and regulation of actin filament length. Located in filopodium tip; photoreceptor inner segment; and photoreceptor outer segment. Is active in stereocilium tip. Is expressed in several structures, including genitourinary system; nervous system; and submandibular gland. Orthologous to human MYO3B (myosin IIIB).
