  • Primary antibody notes
    Myosin VIIa is a member of the myosin superfamily of actin-based motor proteins. Defects in the myosin VIIa gene are responsible for hearing impairment in shaker-1 (sh1) mice and causes Usher syndrome IB in humans. Usher syndrome associates congenital deafness, vestibular dysfunction, and retinitis pigmentosa and is the most common form of combined deafness and blindness. Structural features of myosin VIIa protein include an ATP binding N-terminal motor domain, a central region which possess five light-chain binding (IQ) motifs, and a C-terminal domain with three myosin tail homology (MyTH4) and talin-like homology regions.

  • Relevance
    Myosins are actin-based motor molecules with ATPase activity. Unconventional myosins serve in intracellular movements. Their highly divergent tails are presumed to bind to membranous compartments, which would be moved relative to actin filaments. In retina, myosin VIIa may play a role in trafficking of ribbon-synaptic vesicle complexes and renewal of the outer photoreceptors disks. In inner ear, it may maintain the rigidity of stereocilia during the dynamic movements of the bundle.
